Silicometallophosphate molecular sieves, method of preparation and use

摘要

A new family of crystalline microporous metallophosphates designated MAPSO-64 has been synthesized. These metallophosphates are represented by the empirical formula
R+rMmn+EPxSiyOz
where R is an organoammonium cation such as ETMA+ or DEDMA−, M is a divalent metal such as an alkaline earth or transition metal, and E is a framework element such as aluminum or gallium. The microporous MAPSO-64 compositions BPH topology and have catalytic properties for carrying out various hydrocarbon conversion processes and separation properties for separating at least one component.
