STABLE CATALYST FOR CONVERSION OF ALKYL HALIDE TO OLEFINS

摘要

Disclosed are stable catalysts, and methods for their use, that are capable of producing an olefin from an alkyl halide. The catalysts include a phosphorus-treated silicoalummophosphate (SAPO) having a structure of X/SAPO or X/Z-SAPO, where X includes a non-framework phosphorus and Z is one or more elements from Groups 2A, 3A, IVB, VIB, VIIB, VIII, IB of the Periodic Table, or compounds thereof comprised in the SAPO framework.
