This invention relates to crystalline gallosilicates having the following composition in terms of the mole ratios of the oxides: 0.9+/-0.25M2/nO:Ga2O3:xSiO2:yH2O.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. |
