Abstract
A new family of highly charged crystalline microporous metallophosphate molecular sieves has been synthesized. These metallophosphates are represented by the empirical formula of: Rp+rA+mM2+xEyPOz where A is an alkali metal cation, R is at least one quaternary organoammonium cation, M is a divalent metal such as zinc and E is a trivalent framework element such as aluminum or gallium. This family of high charge density metallophosphate materials are among the first metalloalumino(gallo)phosphate-type molecular sieves to be stabilized by combinations of alkali and quaternary organoammonium cations, enabling unique compositions. This family of high charge density metallophosphate molecular sieves has catalytic properties for carrying out various hydrocarbon conversion processes and separation properties for separating at least one component.
