Title:
PROCESSES FOR PRODUCING MIXTURES OF DIFFERENT OLEFINS
Document Type and Number:
WIPO Patent Application WO/2024/039702
Kind Code:
A3
Abstract:
Processes for producing two or more different C2-C6 linear or branched olefins are disclosed herein. In one exemplary implementation, the process can include contacting a first feed stream that includes γ-valerolactone with one or more first catalysts in a first reactor to form a mixture. The mixture includes two or more different C2-C6 linear or branched olefins at a yield of at least 60%, and the one or more first catalysts include a doped zeolite. Processes for converting levulinic acid to γ-valerolactone are also disclosed herein.
