    摘要: The present invention relates to a process for producing crystalline aluminosilicates having in the hydrogen form an X-ray diffraction pattern substantially as set forth in Table 1 of this specification and the following composition in terms of the mole ratios of the oxides:0.9=0.2 M.sub.2 /.sub.n O:Al.sub.2 O.sub.3 :xSiO.sub.2 :yH.sub.2 O:zNH.sub.3wherein M is at least one cation having a valence n, x is at least 10, y/x is from 0 to 5 and z/x is 0-5. The process comprises mixing a source of silica, a source of alumina, a source of alkali metal(s), water and ammonia until a homogeneous gel is formed and crystallizing the gel at a temperature above 70.degree. C. for a period of at least 2 hours. The crystalline aluminosilicate thus produced can be used, whether or not impregnated and/or ion-exchanged, as catalysts for any one of the following reactions: alkylation, dealkylation, dehydrocyclodimerization, aromatization, transalkylation, isomerization, dehydrogenation, hydrogenation, cracking, cyclization, oligomerization, polymerization, and dehydration reactions.

    摘要: This invention relates to crystalline gallosilicates having the following composition in terms of the mole ratios of the oxides:0.9.+-.0.25M.sub.2 /.sub.n O:Ga.sub.2 O.sub.3 :xSiO.sub.2 :yH.sub.2 O.zQwherein M is at least one cation having a valence n, x is at least 10, y/x is from 0 to 30, Q is a template used in the synthesis of the gallosilicate and z/x is 0-20, wherein the gallosilicate in the organic free hydrogen-form has an X-ray diffraction pattern substantially as set forth in Table A of this specification. The gallosilicates may be used, whether or not impregnated and/or ion-exchanged, admixed, supported or bound, for catalyzing a reaction selected from alkylation, dealkylation, dehydrocyclodimerization, aromatization, transalkylation, isomerization, dehydrogenation, hydrogenation, cracking, hydrocracking, cyclization, oligomerization, polymerization, conversion of carbon monoxide/hydrogen mixtures to hydrocarbons and dehydration reactions.

    摘要: This invention relates to a process for restructuring an olefinic feedstock rich in linear olefins into a product olefin of narrower composition which is richer in branched olefins than the starting feedstock. Such restructuring is achieved by contacting the feedstock with an unmodified or partially modified tectometallosilicate of the Theta-1 type at relatively low temperatures. The product olefins are valuable as petrochemical feedstock for producing polyolefins, alcohols, ethers and other oxygenates, surfactants, alkyl aromatics and oligomers useful as gasoline blending components.
