摘要： Disclosed is a method for preparing crystalline gallosilicates having a molar ratio of SiO.sub.2 /Ga.sub.2 O.sub.3 .gtoreq.5 an having a more uniform particle size with enhanced catalytic activity. According to the method of the invention, crystalline gallosilicates are prepared by adding an aged, gallosilicate nuclei-forming gel having a molar ratio of SiO.sub.2 /Ga.sub.2 O.sub.3 .gtoreq.5 to an aqueous, alkaline solution containing reactive silicon and gallium compounds to form a mixture. The mixture is then subjected to hydrothermal crystallization conditions to form the crystalline gallosilicate. The gallosilicates prepared by the disclosed method is useful for the preparation of catalysts and adsorbents and in processes for converting low molecular weight hydrocarbons to higher aliphatics and aromatic compounds.
