Patent number: 10829372Abstract: Among other things, the present invention encompasses the applicant's recognition that epoxide carbonylation can be performed industrially utilizing syngas streams containing hydrogen, carbon monoxide and varying amounts carbon dioxide. Contrary to expectation, the epoxide carbonylation reaction proceeds selectively in the presence of these mixed gas streams and incorporates excess CO in the syngas stream into valuable chemical precursors, resulting in hydrogen streams substantially free of CO. This is economically and environmentally preferable to performing WSGR which releases the excess carbon as CO2. The integrated processes herein therefore provide improved carbon efficiency for processes based on coal or biomass gasification or steam methane reforming.Type: GrantFiled: February 11, 2020Date of Patent: November 10, 2020Assignee: Novomer, Inc.Inventors: Sadesh H.

Patent number: 9403788Abstract: A method of making acid anhydrides from epoxide and carbon monoxide feedstocks is presented. In various aspects, the method includes steps of reacting the contents of a feed stream comprising an epoxide, a solvent, a carbonylation catalyst and carbon monoxide to produce a first carbonylation product stream comprising a beta-lactone, then reacting the contents of the first carbonylation product stream with additional carbon monoxide to produce a second carbonylation product stream comprising an acid anhydride, and separating at least a portion of the acid anhydride from the second carbonylation product stream to produce: i) an acid anhydride product stream comprising the separated portion of acid anhydride; and ii) a recycling stream comprising the carbonylation catalyst, and finally adding the recycling stream to the feed stream.Type: GrantFiled: February 12, 2013Date of Patent: August 2, 2016Assignee: NOVOMER, INC.Inventors: Han Lee, Michael A.
