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+ rMm 2+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 exhibit the LEV framework topology and have catalytic properties for carrying out various hydrocarbon conversion processes and separation properties for separating at least one component. The materials may be used as a catalytic composite for hydrocarbon conversions or may be used to separate at least one component from a mixture.
