A new family of crystalline microporous metallophosphates designated AlPO-91 has been synthesized. These metallophosphates are represented by the empirical formulan nC c + A a + M m 2+ EP x Si y O z n nwhere M is a divalent framework metal such as magnesium or zinc, C is a cyclic organoammonium cation, A is an acyclic organoammonium cation, and E is a trivalent framework element such as aluminum or gallium. The AlPO-91 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. |
