BACKGROUND OF THE INVENTION 0001 The history of zeolites began with the discovery of stilbite in 1756 by the Swedish mineralogist A. Cronsted. Zeolite means boiling stone and refers to the frothy mass which can result when a zeolite is fused in a blowpipe. Volatile zeolitic water forms bubbles within the melt. 0002 Zeolites are crystalline aluminosilicates having as a fundamental unit a tetrahedral complex consisting of Si4 and Al3 in tetrahedral coordination with four oxygens. Those tetrahedral units of SiO4 and AlO4 are linked to each other by shared oxygens and in this way they form three-dimensional networks. The building of such networks produces channels and cavities of molecular dimensions. Water molecules and charged compensating cations are found inside the channels and cavities of the zeolitic networks. 0003 Even though there was much knowledge about zeolites and its properties, it was until the middle of this century that commercial preparation and use of zeolites was possible. This advance allowed more research into the synthesis and modification of zeolitic materials. 0004 The modification of the physical-chemical properties of zeolitic molecular sieve by the incorporation of other elements different from silicon and aluminum can be achieved through one of the following ways: 0005 1. -Incorporation through ion exchange 0006 2. -Incorporation through impregnation 0007 3. -Incorporation into the synthesis gel. 0008 The most common and well known form of introducing different elements in the channels and cavities of zeolitic molecular sieves is through ion exchanging. In this way, the compensating cation balancing the negative charge of the framework (usually sodium) is replaced by a new cation after ion exchange is done. In this case, the new cation is located inside the channels and cavities of the zeolite but, it is not coordinated with the silicon atoms throughout the oxygen atoms. 0009 The incorporation of other chemical elements in the zeolitic molecular sieve through impregnation is another common way of modifying the properties of zeolitic materials. For this case, most of the element incorporated in the zeolite is found in the surface of the crystallites of the zeolitic material. 0010 The incorporation into the synthesis gel of other chemical elements to produce zeolitic molecular sieves allowed an important advance in this area of research. This variation not only has modified the physical-chemical properties of the zeolitic materials of known structures, but also has given rise to the production of new structures unknown in the aluminosilicate frameworks. 0011 Patent and open literature have shown two important groups of zeolitic molecular sieve which incorporate other elements besides silicon and aluminum. These two main groups are the metallosilicates and the metalloaluminosphosphates. The metallosilicates are molecular sieves in which the aluminum is replaced by another element like gallium, iron, boron, titanium, zinc, etc. The metalloaluminophosphates are molecular sieves in which the aluminophosphate framework is modified by the incorporation of another element like magnesium, iron, cobalt, zinc, etc. 0012 Because the present invention is more related to metallosilicates than to metalloaluminophosphates, the metallosilicates are discussed in more detail. To choose an element to be incorporated into the molecular sieve framework, researchers take into account the possibility that the chosen element can attain tetrahedral coordination as well as the ionic ratio radius of such element. Table 1 shows the elements that can attain a tetrahedral coordination as well as the ionic ratio radius of such elements. 0013 Some of the elements indicated in Table 1 have been claimed to be incorporated into molecular sieve structures of the metallosilicate type.

0015 The conventional preparation of metallosilicates succeeds only if organic structure guiding compounds (organic templates) are added to the synthesis mixture. In general, tetraalkylamonium compounds, tertiary and secondary amines, alcohols, ethers, and heterocyclic compounds are used as organic templates. 0016 All these known methods of producing metallosilicates have a series of serious disadvantages if it is desired to produce them in a commercial scale. For instance, those organic templates used are toxic and easily flammable so, since the synthesis must be carried out under hydrothermal conditions and a high pressure in autoclaves, an escape of these templates into the atmosphere can never be completely prevented. Also, the use of templates increases the cost of production of the material because the template is expensive and because the effluent from the production of the metallosilicate also contains toxic materials which require expensive and careful disposal in order to prevent contamination of the environment. 0017 Adding to this, the metallosilicate obtained has organic material inside the channels and cavities so, to be useful as a catalysts or adsorbent, this organic material must be removed from the lattice. The removal of the organic template is carried out by combustion at high temperatures. The removal of the template can cause damage to the lattice structure of the metallosilicate molecular sieve and thus diminish its catalytic and adsorption properties. 0018 The metalloaluminosilicate is another group of zeolitic molecular sieves that can be prepared, however, research in this area is not as popular as it is with the metalloaluminophosphates and metallosilicates. In spite of that, in the patent literature it is possible to find some examples of this type of materials. The preparation of iron- titano- and galloaluminosilicates can be found in U.S. Pat. Nos. 5,176,817; 5,098,687, 4,892,720; 5,233,097; 4,804,647; and 5,057,203. For those cases, the preparation of the material is by a post synthesis treatment. An aluminosilicate zeolite is put in contact with a slurry of a fluoro salt of titanium or/and iron or a gallium salt and then some of the aluminum is replaced by titanium, iron or gallium. This methodology has some disadvantages because of the extra steps required to produce the material. 0019 The ideal thing to do would be to add the desired element into the synthesis gel and then through a hydrothermal process get the metalloaluminosilicate material. In the patent literature is possible to find some examples of this type of procedure. U.S. Pat. No. 5,648,558 teaches the preparation and use of metalloaluminosilicates of the BEA topology with chromium, zinc, iron, cobalt, gallium, tin, nickel, lead, indium, copper and boron. U.S. Pat. No. 4,670,474 teaches the preparation of ferrimetallosilicates with aluminum, titanium, and manganese. U.S. Pat. No. 4,994,250 teaches the preparation of a galloaluminosilicate material having the OFF topology. U.S. Pat. Nos. 4,761,511; 5,456,822; 5,281,566; 5,336,393; 4,994,254 teach the preparation of galloaluminosilicates of the MFI topology. U.S. Pat. No. 5,354,719 teaches the preparation of metalloaluminosilicates of the MFI topology with gallium and chromium. These examples of metalloaluminosilicates require the use of organic templates or seeding procedures so, these methods of preparation of metalloaluminosilicates have similar problems to those described above for metallosilicate methods of preparation.

SUMMARY OF THE INVENTION 0020 The invention presents a new method for obtaining a new family of aluminosilicate and metalloaluminosilicate materials of MFI topology, and their use in the FCC area. 0021 The synthetic metalloaluminosilicates produced with this inventive method have physical and chemical characteristics which make them clearly distinguishable from other products. The methodology does not use organic templates or seeding procedures. The preparation method developed in the invention allows the incorporation in the synthesis gel of other elements of the periodic table and they are interacted with the source of silicon in an acid medium. In this way, the elements are incorporated in the material prepared and those elements are not ion-exchangeable when the final material is obtained. 0022 The elements that can be incorporated into the aluminosilicate framework of the present invention include those elements from the Groups IIA, IIIB, IVB, VB, VIB, VIIB, VIII, IB, IIB, IIIA, IVA, and VA (using the CAS version nomenclature) of the periodic table. Examples of these are shown in Table 1. The amount of such elements present in the aluminosilicate framework of the present invention may vary depending on the required amount of such element in said material. Also, it is possible to mix more than two elements in a given material of the present invention. However, for all compositions of the present invention, it is a characteristic that at least some of the incorporated elements are not ion-exchangeable by conventional techniques and are present in the aluminosilicate material. The new compositions exhibit X-ray diffraction diagrams which contains certain definable minimum lattice distances. Furthermore, the new metalloaluminosilicate materials show specific absorption bands in the infrared spectrum. Also, the new materials show specific bands in the NMR spectrum analysis. 0023 The method developed for preparing metalloaluminosilicate materials can also be used for preparing aluminosilicate material such as ST5 (U.S. Pat. No. 5,254,327) and other MFI type materials of higher Si/Al ratios given the right conditions. 0024 The materials of the present invention have a composition which may be expressed according to one of the formulas given below in terms of molar ratios of oxides: 21. a(M2/nO) :b(Al2O3) :c(E2O3) :d(SiO2) :e(H2O)2. a(M2/nO) :b(Al2O3) :c(FO2):d(SiO2) :e(H2O)3. a(M2/nO) :b(Al2O3) :c(GO):d(SiO2) :e(H2O)4. a(M2/nO) :b(Al2O3) :c(H2O5) :d(SiO2) :e(H2O)

0025 where M is at least one ion-exchangeable cation having a valence of n; E is an element with valence 3 which is not ion-exchangeable by conventional means; F is an element with valence 4 which is not ion-exchangeable by conventional means; G is an element with valence 2 which is not ion-exchangeable by conventional means; H is an element with valence 5 which is not ion-exchangeable by conventional means; a/b>0; c/b>0; d/b>0; d/c>0; e/b>0; a/(bc)>0; d/(bc)>0; a is from >0 to 6, b is equal to 1, c is from >0 to 10, d is from 10 to 80 and e is from 0 to 100. 0026 The invention is not limited to such wet materials or oxide forms, rather its composition may be present in terms of oxides and on a wet basis (as in the above formulas) in order to provide a means for identifying some of the novel compositions. Furthermore, compositions of the present invention may also incorporate more than one element which are not ion-exchangeable and have different valences (mixtures of E, F, G and H). Other formulas may be written by those skilled in the art to identify particular subsets or embodiments of the present invention which comprises porous crystalline metalloaluminosilicates. 0027 Metalloaluminosilicates of the present invention have useful properties including catalytic activity. These novel compositions may be advantageously employed in known processes which presently use aluminosilicate zeolites. Aluminosilicate compositions of the present invention may be advantageously incorporated with binders, clays, aluminas, silicas, or other materials which are well-known in the art. They also can be modify with one or more elements or compounds by deposition, occlusion, ion-exchange or other techniques known to those skilled in the art to enhance, supplement or alter the properties or usefulness of the aluminosilicate compositions of the present invention. The metalloaluminosilicates of the present invention can be used as additive in the FCC area. 0028 The metalloaluminosilicates of the present invention are prepared by hydrothermal methods and, therefore, the elements incorporated in the aluminosilicate compositions are not ion-exchangeable and form part of the structure of the crystalline aluminosilicate composition. 0029 According to the invention, a method is provided for preparing a metalloaluminosilicate which includes the steps of: providing a solution containing a silica source; providing a solution containing an alumina source; providing an aqueous acid solution containing a metal other than silicon or aluminum; mixing the silica source solution with the aqueous acid solution so as to form a silica source-metal containing mixture; mixing the silica source-metal containing mixture with the alumina source solution so as to provide a gel mixture; and hydrothermally crystallizing the gel mixture so as to provide a metalloaluminosilicate material having an aluminosilicate framework and having the metal incorporated into the aluminosilicate framework. 0030 In further accordance with the invention, a method is provided for preparing aluminosilicate comprising the steps of: providing a solution containing a silica source; providing a solution containing an alumina source; mixing the silica source solution with the aqueous acid solution so as to form a silica source-acid mixture; mixing the silica source-acid mixture with the alumina source solution so as to provide a gel mixture; and hydrothermally crystallizing the gel mixture so as to provide an aluminosilicate composition having an aluminosilicate framework, wherein the composition is formed without organic additives. 0031 A composition is also provided, which comprises a metalloaluminosilicate composition comprising an aluminosilicate composition having an aluminosilicate framework and containing at least one metal incorporated into the aluminosilicate framework.

DETAILED DESCRIPTION OF THE INVENTION 0061 The invention relates to a method for obtaining a new family of matalloaluminosilicate materials of MFI topology and their use in the FCC area. The materials are produced with a simple and advantageously inorganic aqueous alkaline reaction mixture under mild hydrothermal conditions. 0062 The invention further relates to an ST-5 type metalloaluminosilicate and a method for preparing same. In accordance with the invention, the metalloaluminosilicate is advantageously prepared without the need for templating agents and/or seeding procedures. In addition, the method of the present invention advantageously results in a desired metal being located in the crystalline structure or framework of the aluminosilicate material. 0063 The compositions are prepared from a synthesis gel which is provided in a sequential manner. 0064 The preparation of the synthesis gel is carried out by mixing three solutions: an acid solution of the salt of the element to be incorporated, a solution of a silica source and a solution of an alumina source. 0065 The salts of the elements to be incorporated are preferably nitrates, chlorides, sulfates, bromides, and the like. 0066 Acidification of the solution can be done with one or more of sulfuric acid, nitric acid, hydrochloric acid and the like. 0067 The preferred sources of silica are sodium silicate, sodium metalsilicate, coloidal silica and the like. 0068 The preferred sources of alumina are sodium aluminate, aluminum nitrate, aluminum sulfate, and so on. 0069 The solution of the element to be incorporated is preferably prepared by dissolving a weight of the salt in a volume of a diluted acid solution. 0070 The solution of the silica source is prepared by diluting or dissolving an amount of a soluble silica source in a volume of water. 0071 The solution of the alumina source is prepared by dissolving a weight of the aluminum salt in an amount of water. 0072 The metal to be incorporated into the metalloaluminosilicate according to the invention may suitably be one ore or metals from Groups IIA, IIIB, IVB, VB, VIB, VIIB, VIII, IB, IIB, IIIA, IIA, IVA, and VA (CAS), more preferably iron, zinc, zirconium, chromium, nickel, cobalt, magnesium, phosphorous, gallium and mixtures thereof. Particularly desirable metals are iron, zinc and mixtures thereof. 0073 According to the invention, mixing is carried out in a sequential way. The preferred sequence of mixing is, first, to slowly add silica solution under vigorous stirring over the acid solution of the element to be incorporated. After homogenization of the mixture formed, the solution of alumina is added under vigorous stirring. The final mixture is allowed to homogenize for a given period of time. 0074 The gel composition for preparing these metalloaluminosilicate materials is given in the form of molar ratios of elements as follow: 0075 SiO2/Al2O3 from 5 to 80, 0076 SiO2/DOx from 10 to 1500, 0077 SiO2/(Al2O3DOx) from 5 to 70, 0078 Na2O/SiO2 from 0.22 to 2.20, 0079 OH/SiO2 from 0.01 to 2.00, 0080 H2O/SiO2 from 14 to 40, 0081 where D is the element or elements incorporated into the gel. 0082 After homogenization is complete the gel is transferred to an autoclave where hydrothermal crystallization preferably is done. The temperature of the crystallization is preferably in the range of 150 C. to 220 C. with a more preferred range of 165 C. to 185 C. The agitation during crystallization is done with a speed preferably ranging between 40 RPM and 400 RPM, the preferred range is 80 RPM to 300 RPM. The crystallization time preferably ranges from 24 hours to 120 hours with a more preferred range between 36 hours and 76 hours. The crystallization is done at autogenous pressure. After the crystallization time is finished, the aluminosilicate composition is filtered, and washed with water preferably until reaching a pH close to 7. The filtered, washed material is then put to dry at a temperature preferably ranging from 80 C. to 140 C. for a period of about 12 hours. 0083 The metalloaluminosilicate materials obtained according to the invention preferably have a chemical composition which can be described in molar ratios using one of the following formulas: 31. a(M2/nO) :b(Al2O3) :c(E2O3) :d(SiO2) :e(H2O)2. a(M2/nO) :b(Al2O3) :c(FO2) :d(SiO2) :e(H2O)3. a(M2/nO) :b(Al2O3) :c(GO) :d(SiO2) :e(H2O)4. a(M2/nO) :b(Al2O3) :c(H2O3):d(SiO2) :e(H2O)

0084 where M is at least one ion-exchangeable cation having a valence of n, the preferred alkali cation is sodium, however, other alkali cations (lithium, potassium and the like) can be employed; E is an element with valence 3 which is not ion-exchangeable by conventional means, suitable examples include iron, gallium, chromium, boron, indium and the like; F is an element with valence 4 which is not ion-exchangeable by conventional means, suitable examples include titanium, zirconium, germanium, and the like; G is an element with valence 2 which is not ion-exchangeable by conventional means, suitable examples include nickel, zinc, cobalt, magnesium, beryllium and the like; H is an element with valence 5 which is not ion-exchangeable by conventional means, suitable examples include phosphorous, vanadium and the like; a is from >0 to 6; b is equal to 1, c is from >0 to 10; d is from 10 to 80; d/c is from 10 to 1500; e is from 0 to 100; a/(bc) is from >0 to 5; and d/(bc) is from 10 to 70. 0085 The invention is not limited to such wet materials or said oxide forms, rather its composition may be present in terms of oxides and on a wet basis (as in the above formulas) in order to provide a means for identifying some of the novel compositions. Furthermore, compositions of the present invention may also incorporate more than one element which are not ion-exchangeable and have different valences (mixtures of E, F, G and H). Other formulas may be written by those skilled in the art to identify particular subsets or embodiments of the present invention which comprises porous crystalline metalloaluminosilicates. 0086 The present invention advantageously provides a metalloaluminosilicate composition wherein the metal is incorporated into the aluminosilicate framework of the composition. As used herein, the term incorporated means the metal cannot be removed through ion exchange procedure. 0087 In conjunction with the above chemical composition, the metalloaluminosilicates produced with the methodology of the present invention show an X-ray diffraction diagram which contains at least the lattice distances that are listed in Table 2 below. 4TABLE 2Interplanar spacingRelative intensity11.2 0.4strong10.0 0.4strong6.01 0.2weak5.72 0.2weak5.58 0.2weak4.38 0.1weak3.86 0.1very strong3.73 0.1strong3.65 0.1strong3.49 0.1weak3.23 0.1weak3.06 0.06weak3.00 0.06weak2.00 0.04weak

0088 In addition to the above chemical composition and lattice distances listed in Table 2, the metalloaluminosilicates produced according to this invention have absorption bands in the infrared spectrum and NMR spectra which make them different from other materials. Other techniques can be used in some specific cases like Mossbauer spectroscopy for iron, XPS for magnesium, etc. 0089 Infrared spectroscopy is a simple but powerful technique that can yield information concerning structural details of zeolitic materials. The region from 400 to 1500 cm1 is important because in that region can be observed different sets of infrared vibrations related to zeolitic materials, for instance, the internal tetrahedral and external linkages. The infrared spectrum can be classified into two groups of vibrations: 1.internal vibrations of the framework TO4, which are insensitive to structural vibrations; and 2. vibrations related to the external linkage of the TO4 units in the structure. The latter are sensitive to structural variations. This technique has been employed to identify framework incorporation of other elements. Modifications and shift in the asymmetric and symmetric vibrations have been observed with successful incorporation of such new elements in the framework of the zeolitic material. For this reason this is an important characterization of the metalloaluminosilicate materials of the present invention. 0090 Another important characterization of the metalloaluminosilicates of the present invention is 29Si NMR spectroscopy. In silicate systems the Q-unit is used to indicate the different silicate atoms in a system. However, this notation is not sufficient to describe the basic building units in the zeolite or aluminosilicate frameworks. In the zeolite systems, the Q-units are always the Q4, where each silicate is surrounded by four silicate or aluminate units. Thus in zeolites, there are five possibilities, described by Q4 (nAl, (4 n)Si), where n0, 1, 2, 3, 4. 0091 Generally these are noted as Si(nAl) or Si((4n)Si), indicating that each silicon atom is linked via the oxygen, to n aluminum and 4n silicon neighbors. Thus the silicon with four aluminum neighbors would be indicated by Si(4Al). When one or more Si atoms at the Q4 unit position are replaced by Al atoms, a shift in the 29Si chemical shift occurs. 0092 In the case of the metalloaluminosilicate of the present invention, besides Al atoms there are other atoms incorporated into the structure of the material, so the shift in the chemical shifts are due to them, because for a material with a given silicon to aluminum molar ratio the shifts due to aluminum are fixed, so the modification in the 29Si NMR chemical shift is caused by the other element incorporated in the structure which is linked to the silicon through the oxygen atoms. 0093 Mossbauer spectroscopy was used to confirm the incorporation of iron into the aluminosilicate framework of the ferrimetalloaluminosilicate material of Example 3 below. The Mossbauer spectra of this material showed a broad singlet at room temperature indicative of iron in a tetrahedral coordination with oxygen. 0094 X-ray photoelectron spectroscopy is a technique that has been used in the characterization of the incorporation of magnesium into the framework of magnesoaluminophosphates (Zeolites 15: 583-590, 1995). When the magnesium is coordinated tetrahedrally with four oxygens as in the case of the magnesoaluminophosphate the value of the binding energy for the Mg2p signal is about 50.1 eV. For Example 20 below, this technique was used and the value of the binding energy of the signal Mg 2p was 49.8 which is close to the value found for magnesium in the magnesoaluminophosphate. 0095 The compositions of the present invention can be converted to protonic form, for example by ion exchange, with the help of a mineral acid, an ammonium compound, other proton suppliers, or with other cations. An important aspect of the invention is that the elements incorporated in the framework of the material are not ion-exchangeable, and therefore, they are not lost when ion exchange is done. The modified materials can be used in catalytic reactions as pure materials or in combination with other materials like clays, silicas, aluminas and other well known fillers. 0096 Metalloaluminosilicates of the present invention have useful properties including catalytic activity. These novel compositions may be advantageously employed in known processes which presently use aluminosilicate zeolites. Aluminosilicate compositions of the present invention may be advantageously incorporated with binders, clays, aluminas, silicas, or other materials which are well-known in the art. They also can be modified with one or more elements or compounds by deposition, occlusion, ion-exchange or other techniques known to those skilled in the art to enhance, supplement or alter the properties or usefulness of the aluminosilicate compositions of the present invention. The metalloaluminosilicates of the present invention can be used as additive in the FCC area. 0097 The metalloaluminosilicate compositions of the present invention are prepared by hydrothermal methods so, the elements incorporated in the aluminosilicate compositions are not ion-exchangeable and form part of the structure of the crystalline aluminosilicate compositions. 0098 In accordance with the present invention, a method is provided which is advantageous for preparing metalloaluminosilicate compositions, and which is also advantageous in preparing aluminosilicate compositions themselves. 0099 In preparation of aluminosilicate compositions, a composition such as that identified as ST5 aluminosilicate (U.S. Pat. No. 5,254,327) can be prepared through sequentially mixing three solutions as described above. 0100 In order to prepare an aluminosilicate composition, a first solution is prepared containing a silica source composition. A second solution is prepared containing an alumina source and a third aqueous acid solution is prepared. The silica source is then mixed with the aqueous acid solution so as to form a silica source-acid mixture, and the silica source-acid mixture is then preferably mixed with the alumina source solution so as to provide a gel mixture which can be hydrothermally crystallized so as to provide an aluminosilicate composition having an aluminosilicate framework. This composition is advantageously formed without the need for templating agents or seeding or other organic additives, and provides an aluminosilicate composition similar to ST5 which can advantageously be used for various catalystic applications. In this method, as with the method for preparing metalloaluminosilicates as discussed above, the sequence of first mixing silica source solution with acid or acid metal solution, followed by mixing with an alumina source solution to provide the desired gel mixture advantageously provides for formation of the desired aluminosilicate framework structure without the need for seeding or templating agents and, in the case of metalloaluminosilicates, advantageously incorporating the desired metal into the aluminosilicate framework. 0101 The new materials and their preparation methods will be better understood by reference to the following examples. 0102 The raw materials used in the examples are: commercial sodium silicate GLASSVEN (28.60 wt % SiO2, 10.76 wt % Na2O, 60.64 wt % H2O), commercial sodium silicate VENESIL (28.88 wt % SiO2, 8.85 wt % Na2O, 62.27 wt % H2O), Sulfuric acid from Fisher or Aldrich (98 wt %, d1.836), Phosphoric acid from Aldrich (85 wt %), sodium aluminate LaPINE (49.1 wt % Al203, 27.2 wt % Na2O, 23.7 wt % H2O), the salts of the different elements to be incorporated are A.C.S reagent grade or Analytical grade from Aldrich. 0103 The first two examples are to demonstrate the use of the method of the present invention for preparation of aluminosilicates of MFI topology without seeding or templates.
