PROCESS FOR CONVERSION OF LOWER ALIPHATIC OXYGENATES TO OLEFINS AND AROMATICS WITH GALLIUM CONTAINING ZSM-5 CATALYST

摘要

C2-C5 olefins and aromatics are prepared by catalytic conversion of lower aliphatic C1-C4 oxygenates in the presence of a medium pore gallium containing zeolite catalyst having a ZSM-5 framework at elevated conversion temperatures. The process favors production of valuable unsaturated hydrocarbons with low paraffin output.
