| 摘要 |
The present invention relates to crystalline gallosilicates having a mordenite type structure, to methods of preparing the same, and the use thereof as catalysts in hydrocarbon conversion reactions. The gallosilicates have different acidity properties to the analogous MOR-type conventional aluminosilicates and can be produced by crystallisation from a mixture containing gallia, silica, alkali metal(s), water and a template. The gallosilicates can be used, whether or not impregnated and/or ion-exchanged, admixed, supported or bound as catalysts for any of the following reactions: alkylation, dealkylation, dehydrocyclodimerisation, aromatisation, transalkylation, isomerisation, dehydrogenation, hydrogenation, cracking, hydrocracking, cyclisation, oligomerisation, polymerisation, and dehydration reactions, or for conversion of carbon monoxide/hydrogen mixtures to hydrocarbons. |
