Abstract
This invention relates to crystalline gallosilicates having the following composition in terms of the mole ratios of the oxides: EQU 0.9.+-.0.25M.sub.2 /.sub.n O:Ga.sub.2 O.sub.3 :xSiO.sub.2 :yH.sub.2 O.zQ wherein 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.
