METALLOPHOSPHATE MOLECULAR SIEVES, METHOD OF PREPARATION AND USE

摘要

A new family of crystalline microporous metallophosphates designated AlPO-67 has been synthesized. These metallophosphates are represented by the empirical formula;R+rMm2+EPxSiyOz ;where R is an organoammonium cation such as the ETMA+ or DEDMA+, M is a framework metal alkaline earth or transition metal of valence 2+, and E is a trivalent framework element such as aluminum or gallium. The AlPO-67 compositions have the LEV topology and have catalytic properties for carrying out various hydrocarbon conversion processes, and separation properties for separating at least one component.
