PROCESS FOR CONVERSION OF LOWER ALIPHATIC ETHERS TO AROMATICS AND LOWER OLEFINS

摘要

The invention relates to a process for converting a feed stream consisting of reactive components and an optional feed diluent to a product stream comprising aromatic hydrocarbons and C2 C3 olefins wherein the reactive components comprise at least 90 vol% of an aliphatic ether selected from the group consisting of methyl tertiary butyl ether and ethyl tertiary butyl ether the process comprising the step of contacting the feed stream with a catalyst composition comprising a zeolite catalyst wherein the zeolite catalyst is a zeolite modified by Ga and an element M1 selected from the group consisting of Zn Cd and Cu.
