Abstract

A new family of crystalline microporous metallophosphates designated AlPO-78 has been synthesized. These metallophosphates are represented by the empirical formula R+rMm2+EPxSiyOz where R is an organoammonium cation, M is a framework metal alkaline earth or transition metal of valence +2, and E is a trivalent framework element such as aluminum or gallium. The AlPO-78 compositions are characterized by a new unique ABC-6 net structure, and have catalytic properties suitable for carrying out various hydrocarbon conversion processes, as well as characteristics suitable for the efficient adsorption of water vapor in a variety of applications, such as adsorption heat pumps.
