Patent number: 8728782Abstract: Disclosed is a method of converting butyric acid contained in a fermentation broth into biofuel. This chemical conversion method includes separating biohydrogen from gases generated in the course of production of butyric acid through fermentation of carbohydrate, extracting butyric acid from the broth using an insoluble solvent, esterifying butyric acid thus producing butylbutyrate, and hydrogenolyzing all or part of butylbutyrate, thus obtaining butanol. Thereby, biobutanol can be efficiently and economically produced, and butylbutyrate, which has oxidation stability superior to that of conventional biodiesel (fatty acid methyl ester) and is thus regarded as novel biofuel, can be produced together.Type: GrantFiled: March 27, 2009Date of Patent: May 20, 2014Assignees: SK Innovation Co., Ltd., Korea Institute of Science and TechnologyInventors: Sin Young Kang, Cher Hee Park, Young Seek Yoon, In Ho Cho, Hyung Woong Ahn, Sam Ryong Park, Jong Hee Song, Seong Ho Lee, Byoung In Sang, Young Woong Suh, Young Soon Um, Sun Mi Lee

Publication number: 20110300596Abstract: The present invention relates to a preparation method for alcohol by reacting carboxylic acid, alcohol, and hydrogen using hydrogenation catalysts. More specifically, the invention relates to a method for preparing alcohol by performing esterification and hydrocracking in a one-step process using hydrogenation catalysts instead of a two-step process. According to the invention, alcohol is prepared from carboxylic acid through esterification and hydrogenation in a one-step process using hydrogenation catalysts. Therefore, production costs and by-product treatment costs can be reduced in comparison to a two-step process. In addition, the invention is effective and economical since it can produce alcohol at relatively high yield by a simple process. Further, the invention allows high yield at relatively lower pressure when compared to alcohol production from carboxylic acid through hydrogenation without esterification and solves the problems of leaching by catalysts.Type: ApplicationFiled: December 10, 2009Publication date: December 8, 2011Applicant: SK INNOVATION CO., LTD.Inventors: Seong Ho Lee, Seung Hoon Oh, Young Seek Yoon, In Ho Cho, Sin Young Kang, Gi Ho Goh, Cher Hee Park, Hee Soo Kim
