Abstract
A family of highly charged crystalline microporous metallophosphate molecular sieves designated PST-17 has been synthesized. These metallophosphates are represented by the empirical formula of: Rp+rAm+MxEyPOz where A is an alkali metal such as potassium, R is a quaternary ammonium cation such as ethyltrimethylammonium, M is a divalent metal such as zinc and E is a trivalent framework element such as aluminum or gallium. The PST-17 family of molecular sieves are stabilized by combinations of alkali and organoammonium cations, enabling unique metalloalumino(gallo)phosphate compositions and exhibit the BPH topology. The PST-17 family of molecular sieves has catalytic properties for carrying out various hydrocarbon conversion processes and separation properties for separating at least one component.
