Processes for the production of hydrogenated products
View Patent ↗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.
1. A process for making a hydrogenated product comprising:
(a) Providing a clarified MAS-containing fermentation broth;
(b) distilling the broth under super atmospheric pressure at a temperature of >100° C. to about 300° C. to form an overhead that comprises water and ammonia, and a liquid bottoms that comprises SA, and at least about 20 wt % water;
(c) cooling and/or evaporating the bottoms to attain a temperature and composition sufficient to cause the bottoms to separate into a liquid portion and a solid portion that is substantially pure SA;
(d) separating the solid portion from the liquid portion;
(e) recovering the solid portion;
(f) hydrogenating the solid portion in the presence of at least one hydrogenation catalyst to product the hydrogenated product comprising at least one of THF, GBL and BDO; and
(g) recovering the hydrogenated product.
