PROCESS FOR DEHYDROAROMATIZATION OF ALKANES WITH IN-SITU HYDROGEN REMOVAL

摘要

A process for conversion of natural gas to aromatic hydrocarbons in a catalytic membrane reactor is described herein. The catalytic membrane reactor comprises a dehydrogenation catalyst and a membrane that can selectively transport hydrogen under high temperature operating conditions such as 600 °C to 800 °C. Aromatic hydrocarbons are produced stably for a long time by a process characterized by hydrogen co-feed with the reaction gases to the one end of the to the reaction zone while hydrogen is extracted selectively with use of the membrane as the reactive gas mix passes through the reaction zone.
