Title:
PRODUCTION OF LOWER OLEFINS FROM HYDROGENATION OF CO2
Document Type and Number:
WIPO Patent Application WO/2018/045652
Kind Code:
A1
Abstract:
Disclosed is a process for the production of lower olefins by the conversion of a feed stream comprising carbon dioxide and hydrogen, and catalysts as used therein. By virtue of the invention, lower olefins can be produced from hydrogenation of CO2, with high selectivity (the selectivity of lower olefins is up to 80％), and low production of methane (only below 3％). The catalysts used herein were composed with two parts, including multi-metal oxide and zeolite. The two parts can be mixed by mechanical mixing and other methods. The multi-metal oxides mainly constitute the Zn and Zr oxide. The zeolites (eg. SAPO-34) exhibited the suitable acid properties. The composite catalysts not only show a high selectivity of lower olefins, but also a high catalyst activity and chemical and mechanical stability.
