PROCESSES FOR EFFICIENT AND SUSTAINED PRODUCTION OF C₂ TO C₄ OLEFINS

摘要

A process for preparing C₂ to C₄ olefins includes introducing a feed stream of hydrogen gas and a carbon-containing gas into a reaction zone of a reactor and converting the feed stream into a product stream including C₂ to C₄ olefins in the reaction zone in the presence of a hybrid catalyst and in a non-oxidative atmosphere. The hybrid catalyst includes a metal oxide catalyst component comprising gallium oxide and zirconia, and a microporous catalyst component having an 8 membered ring structure. The process also includes periodically introducing an oxidative atmosphere into the reaction zone.
