Patent number: 9018127Abstract: A reduced metallic catalyst or pre-activated catalyst is formed by contacting a precursor catalyst or a reduced metallic catalyst with a modifier solution in the presence of a source of hydrogen and heat treating the precursor catalyst or the reduced metallic catalyst at super-atmospheric pressure to obtain the reduced metallic catalyst from the precursor catalyst or the pre-activated catalyst from the reduced metallic catalyst. A method of hydrogenating a hydrogenatable precursor includes providing a reduced metallic catalyst or the pre-activated catalyst prepared with modifier buffer and contacting the reduced metallic catalyst or pre-activated catalyst with the hydrogenatable precursor in the presence of hydrogen and, optionally, in the presence of a modifier solution.Type: GrantFiled: January 8, 2013Date of Patent: April 28, 2015Assignee: BioAmber International S.a.r.l.Inventors: Setrak K. Tanielyan, Robert L. Augustine, Leo E. Manzer, James F. White, Ramesh D. Bhagat, Balaraju Miryala

Patent number: 8466300Abstract: A process for making a hydrogenated product includes providing a clarified DAS-containing fermentation broth; distilling the broth under super atmospheric pressure at a temperature of >100° C. to about 300° C. to form an overhead that includes water and ammonia, and a liquid bottoms that includes SA, and at least about 20 wt % water; cooling the bottoms to a temperature sufficient to cause the bottoms to separate into a liquid portion in contact with a solid portion that is substantially pure SA; separating the solid portion from the liquid portion; recovering the solid portion; hydrogenating the solid portion in the presence of at least one hydrogenation catalyst to produce the hydrogenated product including at least one of THF, GBL or BDO; and recovering the hydrogenated product.Type: GrantFiled: March 18, 2011Date of Patent: June 18, 2013Assignee: BioAmber International S.a.r.l.Inventors: Olan S. Fruchey, Leo E. Manzer, Dilum Dunuwila, Brian Terry Keen, Brooke Ashley Albin, Nye A. Clinton, Bernard Duane Dombek

Patent number: 8399687Abstract: A process for making a hydrogenated product includes providing a clarified DAS-containing fermentation broth, distilling the broth to form an overhead that includes water and ammonia, and a liquid bottoms that includes MAS, at least some DAS, and at least about 20 wt % water, cooling and/or evaporating the bottoms, and optionally adding an antisolvent to the bottoms, to attain a temperature and composition sufficient to cause the bottoms to separate into a DAS-containing liquid portion and a MAS-containing solid portion that is substantially free of DAS, separating the solid portion from the liquid portion, recovering the solid portion, hydrogenating the second solid portion in the presence of at least one hydrogenation catalyst to produce the hydrogenated product comprising at least one of THF, GBL or BDO, and recovering the hydrogenated product.Type: GrantFiled: December 22, 2011Date of Patent: March 19, 2013Assignee: BioAmber International S.a.r.l.Inventors: Olan S.
