Patent number: 4898660Abstract: A novel family of crystalline, microporus aluminophosphate compositions is synthesized by hydrothermal crystallization at elevated temperatures of aluminophosphate gels containing a molecular structure forming template. The family comprises a number of distinct species, each with a unique crystal structure. Calcination removes volatile extraneous matter from the intracrystalline void space and yields microporus crystalline adsorbents with uniform pores, the dimensions of which vary, among the individual species, from about 3A to 10A diameter. The composition exhibit properties somewhat analogous to zeolitic molecular sieves which render them useful as catalysts or catalyst bases in chemical reactions such as hydrocarbon conversions.Type: GrantFiled: October 20, 1983Date of Patent: February 6, 1990Assignee: Union Carbide CorporationInventors: Stephen T. Wilson, Brent M. Lok, Edith M. Flanigen
