Crystalline silicoaluminophosphates

摘要

A novel class of crystalline microporous silicoaluminophosphates is synthesized by hydrothermal crystallization of silicoaluminophosphate gels containing a molecular structure-forming templating agent. The class comprises a number of distinct species, each with a unique crystal structure. The compositions exhibit properties somewhat analogous to zeolitic molecular sieves which render them useful as adsorbent or catalysts in chemical reactions such as hydrocarbon conversions.
