Hydrocarbon/oxygenate conversion using crystalline (metallo) silicates and germinates SUZ-2

The present invention related to hydrocarbon or oxygenate conversion using novel crystalline silicates, germanates, metallosilicates and metallogermanates.
The present invention provides a crystalline material having, in the dehydrated form, the empirical formula:
m(M.sub.2/a O):X.sub.z O.sub.xz/2 :yYO.sub.2 (I)
in which m is 0.5 to 1.5; M is a cation of valency a; X is a metal of valency x, selected from aluminium, boron, gallium, zinc, iron and titanium; z is 2 when x is an odd number, and z is 1 when x is an even number; y is at least 5; and Y is silicon or germanium; and having, in the calcined hydrogen form, an X-ray diffraction pattern including significant peaks substantially as shown in Table I herein.
The material according to the invention is referred to herein as SUZ-2. The material can be regarded as a metallosilicate or metallogermanate, or as a silicate or germanate when y is very high.
Preferably X is gallium or, especially, aluminium. Preferably Y is silicon. The material may contain two or more different metals X, and/or both silicon and germanium. When X is aluminium and Y is silicon, the material is an aluminosilicate, or zeolite.
As is common in this field, it should be understood that in addition to the elements represented in the general formula I, the material may be hydrated by water in addition to any present when M is hydrogen. The material may also include occluded or adsorbed materials such as alcohols or nitrogenous materials originally present in the synthesis mixture or resulting from reaction of materials originally present. Further, the material may contain more cations M than necessary to balance the charge associated with metal X. This phenomenon is described, for example, in J. Chem. Soc. Chem. Commun. 1985, pp. 289-290. All such materials should be understood to be within the range of the invention.
The cation M may for example be selected from H.sup.+, ammonium, alkali metal cations, alkaline earth metal cations, organic nitrogen containing cations, aluminium cations, gallium cations and mixtures thereof. The cations M present in the material as initially prepared will of course depend on the substances present in the synthesis gel. Commonly, an alkali metal, especially sodium and/or potassium will be present, possibly along with cations of organic nitrogen-containing materials. Those cations initially present may if desired be replaced either wholly or partially by other cations e.g. hydrogen ions or metal cations using conventional ion exchange techniques. The hydrogen form (i.e. M=H.sup.+) may be produced by known methods such as acid exchange or ammonium exchange followed by a thermal treatment, or a combination of the two. For many applications, it may be useful to produce SUZ-2 in the calcined hydrogen form.
Occluded or adsorbed materials may if desired be removed by thermal and/or chemical techniques.
As stated above, material SUZ-2 may be prepared by reacting together under aqueous alkaline conditions the following materials: a source of oxide YO.sub.2 ; water, quinuclidine or its precursor or reaction product; and tetraethylammonium hydroxide or halide or its precursor or reaction product; plus if desired, a source of oxide X.sub.z O.sub.xz/2 and a source of M(OH).sub.a ; the reaction conditions being selected and maintained such as to produce crystals of SUZ-2. Preferably the reaction mixture has components in the following solar ratios: YO.sub.2 X.sub.z O.sub.xz/2 =at least 10, e.g. 10 to 80, especially 20 to 60, most preferably 25 to 45; quinuclidine or derivative/tetraethylammonium compound=0.1 to 3.0, especially 0.5 to 2.0, most preferably 0.6 to 1.5; H.sub.2 O/YO.sub.2 =4 to 500, especially 5 to 200, most preferably 7 to 50; OH.sup.- H.sub.2 O=less than 0.04, especially less than 0.02, most preferably 10.sup.-4 to 0.01; quinuclidine or derivative plus tetraethylammonium compound/YO.sub.2 =0.01 to 2.0, especially 0.01 to 1.0, most preferably 0.1 to 0.5. OH.sup.- should be understood to be defined as follows:
a[no. of moles of M(OH).sub.a)-(no. of moles of M(OH).sub.a associated with X.sub.z O.sub.xz/2)]
It should be understood that even if no source of oxide X.sub.z O.sub.xz/2 or source of M(OH).sub.a is deliberately added to the reaction mixture, the resulting material will inevitably contain small amounts of element X or metal cations M, particularly aluminium and sodium, present as impurities in the reactants or as contaminants of the equipment used.
Following synthesis, it is possible to adjust the value of y by conventional chemical techniques. For example, y may be increased by treatment with acid, silicon tetrachloride, ammonium hexafluorosilicate or a combination of steaming and ammonium ion exchange. All these treatments tend to remove element X from the framework. y may be reduced by treatment with, for example, sodium aluminate, gallate, zincate or titanate, or similar treatments which introduce X into the framework.
The source of oxide YO.sub.2 may for example be sodium silicate, silicic acid, precipitated silica, colloidal silica, or the germanium equivalent.
The source of oxide X.sub.z O.sub.xz/2, if used, may be an aluminium salt, aluminium hydroxide, aluminium oxide, or a metal aluminate; or the equivalent for other metals X. The use of a metal aluminate, especially sodium aluminate, is preferred.
The source of M(OH).sub.a may for example be an alkali or alkaline earth metal hydroxide, for example sodium, potassium, magnesium or calcium hydroxide. A mixture of different materials, for example sodium hydroxide plus potassium hydroxide, may be used.
The reaction mixture may also if desired contain an alcohol, for example methanol. If alcohol is present, then the molar ratio is preferably alcohol/YO.sub.2 =up to 200, especially up to 100, most preferably up to 50.
The reaction mixture is maintained under crystallization conditions until crystals of the desired product SUZ-2 are formed. In general a reaction temperature of from 100 to 250.degree. C. under autogenous pressure is suitable, and an optimum reaction time can be determined by monitoring the course of the reaction.
It has been found that the material SUZ-2 as prepared contains relatively large amounts of nitrogenous material, probably quinuclidine or a reaction product thereof, occluded within its pores. Other materials which may be present include tetraethylammonium hydroxide, or reaction products thereof.
As is common in zeolite synthesis, the precise way in which the reaction is carried out will affect the end product. Particular combinations of parameters may be used to optimize the yield of SUZ-2. Such optimization is a routine part of zeolite synthesis. The novel product SUZ-2 may under some circumstances be co-produced with other crystalline materials. It is for example often produced in admixture with mordenite. The alkalinity of the reaction mixture may be a particularly important parameter; for a mixture having a fixed Si/Al ratio, a higher alkalinity appears to lead to a product having a lower Si/Al ratio. The Si/Al ratio of the product will in any event be lower than or equal to the Si/Al ratio of the reaction mixture. Particular reaction conditions which lead to the product of SUZ-2 are given in the Examples herein.
Material SUZ-2 has a variety of potential applications particularly as a catalyst or adsorbent. As is common in the field of zeolites and zeolite-type materials, it may be used in a number of purifications or separations, and a number of catalytic conversions, for example the conversion of hydrocarbons and oxygenates into other products. In addition to its intrinsic activity conferred by its porous crystalline structure, it may also be subjected to exchange or impregnation with an element suitable for imparting a specific type of catalytic activity. Metal or non-metal compounds which may be used for ion-exchange and/or impregnation may for example be compounds of any one of the following elements, namely those belonging to Groups IB, IIA, IIB, IIIA, IIIB, IVA, IVB, VA, VIB, VIIB and VIII according to the Periodic T able due to Medeleef. Specifically, compounds of copper,. silver, zinc, aluminium, gallium, indium, thallium, lead, antimony, bismuth, chromium, molybdenum, tungsten, manganese, iron, cobalt, nickel, ruthenium, rhodium, palladium, iridium, platinum, rhenium and phosphorus are preferred.
Throughout this Specification, it should be understood that reference to an X-ray diffraction pattern indicates a powder diffraction pattern obtained on a conventional fixed-slit X-ray diffractometer using copper K-alpha radiation. Table I gives the positions of significant peaks present in the XRD of fully calcined SUZ-2 in the hydrogen form. It should be understood that the complete XRD's may contain peaks in addition to those listed in the Table. In addition, where peaks are close together, two or more peaks may, through lack of resolution, appear as a single peak. For example, the peaks at 7.1 and 7.0 in Table I may appear as a single peak. XRD's are of course obtained from experimental samples. Where a material is produced in admixture with another material, unknown peaks resulting from the first material may be hidden underneath peaks at the same position attributable to the second material. It will also be understood that the intensities of the peaks can vary widely depending on a number of factors, notably the presence of non-framework materials. The presence of water, alcohol or nitrogenous materials present in or resulting from the original synthesis gel, may alter the relative intensities of the peaks at different d-spacings. Other factors which can affect the details of the XRD include the molar ratio of X to Y and the particle size and morphology of the sample. It will be appreciated that the XRD patterns presented in the Examples hereinafter are those actually obtained from various samples of calcined and uncalcined SUZ-2. Data were collected on a Philips PW 1050 goniometer fitted with a fixed divergence slit (1/4 degree) in the incident beam and a graphite monochrometer in the diffracted beam. Theta is the Bragg angle; I is the intensity of a peak; and I.sub.o is the intensity of the strongest peak. Philips AFD 1700 processing software was used to determine d-spacings (in angstrom units) and relative intensities (100.times.I/I.sub.o) with copper radiation, copper K-alpha one wavelength=1.54056 Angstroms.

EXAMPLE 9
The zeolite powder from Example 7 was pressed into a tablet at 7 tons per square inch of pressure. The tablet was crushed and sieved to pass through 500 micron but not 250 micron sieves. 4.3 cm.sup.3 of this catalyst was loaded into a reactor and activated as follows: the temperature of the catalyst was raised by 10.degree. C./minute until it plateaued at 500.degree. C. which was sustained for 3 hours and then the reactor was cooled to 300.degree. C. A flow of hydrogen (75 cm.sup.3 /minute) was maintained throughout this treatment. The catalyst was tested for the conversion of a liquid feed consisting of a 2:1 (by volume) mixture of hexadecane and dodecene at 300.degree. C., LHSV of 1.5 and pressure of 20 barg. A gas flow consisting of 2:1 hydrogen and carbon monoxide was cofed with the liquid feed at GHSV of 1248.
