Abstract
A family of highly charged crystalline microporous metallophosphate molecular sieves designated PST-19 has been synthesized. These high charge density metallophosphates are represented by the empirical formula of: Rp+rA+mM2+xEyPOz where A is an alkali metal such as potassium, R is an organoammonium cation such as tetraethylammonium, M is a divalent metal such as zinc and E is a trivalent framework element such as aluminum or gallium. The PST-19 family of materials are among the first MeAPO-type molecular sieves to be stabilized by combinations of alkali and quaternary ammonium cations, enabling unique compositions. The PST-19 family of molecular sieves has the SBS topology and catalytic properties for carrying out various hydrocarbon conversion processes and separation properties for separating at least one component.
