ABSTRACT:
A novel family of crystalline, microporous gallophosphate compositions is synthesized by hydrothermal crystallization at elevated temperatures from gallophosphate gels containing a molecular structure-forming template. The family comprises distinct species, each with a unique crystal structure. Calcination removes volatile extraneous matter from the intracrystalline void space and yields microporous crystalline adsorbents with pores, the dimensions of which vary, among the individual species, from about 3A to 10A in diameter. The compositions represent a new class of adsorbents of the molecular sieve type, and also exhibit properties somewhat analogous to zeolitic molecular sieves which render them useful as catalysts or catalyst bases in chemical reactions such as hydrocarbon conversions.
