Patent ID: 10710892

Abstract:
A method of making and using a new family of crystalline microporous metalloalumino(gallo)phosphosilicate molecular sieves is disclosed. These molecular sieves have been synthesized and are designated high charge density (HCD) MeAPSOs. These metalloalumino(gallo)phosphosilicates are represented by the empirical formula of: Rp+rA+mM2+wExPSiyOz  where A is an alkali metal such as potassium, R is at least one quaternary ammonium cation such as ethyltrimethylammonium, M is a divalent metal such as Zn and E is a trivalent framework element such as aluminum or gallium. This family of metalloalumino(gallo)phosphosilicate materials is stabilized by combinations of alkali and quaternary ammonium cations, enabling unique, high charge density compositions. The HCD MeAPSO family of materials have catalytic properties for carrying out various hydrocarbon conversion processes and separation properties for separating at least one component.
