METALLOPHOSPHATE MOLECULAR SIEVES, METHODS OF PREPARATION AND USE

摘要

A new family of crystalline microporous metallophosphates designated AlPO-57 has been synthesized. These metallophosphates are represented by the empirical formula R+rMmn+EPxSiyOz where R is an organoammonium cation such as the DEDMA+, M is a divalent framework metal such as an alkaline earth or transition metal, and E is a framework element such as aluminum or gallium. The microporous AlPO-57 compositions are characterized by a new unique ABC-6 net structure and have catalytic properties for carrying out various hydrocarbon conversion processes and separation properties for separating at least one component.
