Patent number: 10337035Abstract: The present invention provides a fed-batch culture method comprising a step of fed-batch-feeding a carbon source base and a base in such a manner that the pH level can be maintained at a level suitable for the growth of microorganisms for fermentation of a carbon source. The present invention also provides a method for preparing organic acids using the fed-batch culture method. The present invention fed-batch-feeds a neutralizing agent such as ammonium bicarbonate, ammonium carbonate or alkali metal-containing weak base, and a carbon source substrate in preparing organic acids by microorganism fermentation. Thus, a pH level suitable for the survival of microorganisms for carbon source fermentation can be maintained, and the speed of injecting the carbon source base which is the source material can be appropriately adjusted.Type: GrantFiled: May 21, 2013Date of Patent: July 2, 2019Assignees: SK INNOVATION CO., LTD., SK ENERGY CO., LTD.Inventors: Jae Yeon Park, Sin Young Kang, Woo Chan Park, Min Su Koo, In Ho Cho, Joong Min Park, Seung Yeop Lee, Dong Hyun Kim

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

Publication number: 20040060841Abstract: Disclosed are a booklet blister package and its manufacturing method, in which a description is seal-attached to the blister package on a side of the lid foil. By the package and method, a user can safely use contents in the package, and the manufacturing cost of the package can be reduced. The method comprises the steps of: putting contents in the blister cavity formed on the base film; sealing a lid foil to the base film in such a manner as that the contents are filled between the base film and the lid foil; supplying a description from a description feeding roll and locating the description on the lid foil; selectively seal-attaching the description onto one edge of blister package on a side of the lid foil; and punching predetermined portions of the blister package sealed description, so as to produce a booklet blister package.Type: ApplicationFiled: August 8, 2003Publication date: April 1, 2004Inventors: Young Sun Park, Sin Young Kang

Patent number: 5907186Abstract: A lead-on-chip lead frame adapted to mount a chip divided into two independent circuit blocks thereon, the independent circuit blocks having pads arranged laterally and symmetrically with respect to a central portion of the chip, respectively. The lead-on-chip lead frame has a plurality of elongated common leads each adapted to wire-bond pads of each pad pair having the same function respectively arranged on the circuit blocks, each common lead extending laterally from the central portion of the chip in such a manner that it is lead out beyond a desired side edge of the chip. In this lead frame, the number of leads is reduced, thereby minimizing the size of the package.Type: GrantFiled: May 27, 1997Date of Patent: May 25, 1999Assignee: Hyundai Electronics Industries Co., Ltd.Inventors: Sin Young Kang, Hong Seok Kim, Jung Tae Kwon
