Publication number: 20230062065Abstract: 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.Type: ApplicationFiled: December 14, 2020Publication date: March 2, 2023Applicant: Dow Global Technologies LLCInventors: Joseph F. DEWILDE, Adam CHOJECKI, Alexey KIRILIN, Ewa A. TOCHA-BIELAK, David F. Yancey, Glenn Pollefeyt, Davy L.S. NIESKENS, Andrzej MALEK

Publication number: 20230052682Abstract: A process for preparing C2 to C4 hydrocarbons includes introducing a feed stream into a reaction zone of a reactor, the feed stream comprising hydrogen gas and carbon monoxide. An additional stream is introduced into the reaction zone of the reactor, the additional stream comprising carbon dioxide. A combined stream that includes the feed stream and the additional stream is converted into a product stream comprising C2 to C4 hydrocarbons in the reaction zone in the presence of a hybrid catalyst. The hybrid catalyst includes a mixed metal oxide catalyst component, and a microporous catalyst component. The process operates at a gas hourly space velocity in excess of 2500 hr-1 and effectively yields a net carbon dioxide selectivity of less than 5.0% and a productivity of C2-C4 hydrocarbons greater than 75 g hydrocarbons per kilogram of catalyst per hour.Type: ApplicationFiled: December 2, 2020Publication date: February 16, 2023Applicant: Dow Global Technologies LLCInventors: Glenn Pollefeyt, Davy L.S.
