Patent number: 8911613Abstract: Disclosed is a method of simultaneously manufacturing high quality naphthenic base oil and heavy base oil using a single catalyst system, by subjecting an oil fraction (slurry oil or light cycle oil) produced by fluid catalytic cracking and an oil fraction (deasphalted oil) produced by solvent deasphalting to hydrotreating, catalytic dewaxing and hydrofinishing of the single catalyst system, thereby obtaining not only products having low viscosity but also heavy base oil products (150BS) having high viscosity which was impossible to obtain using a conventional catalytic reaction process, and also thereby producing base oil products having different properties using the single catalyst system, thus generating economic benefits and exhibiting superior efficiency.Type: GrantFiled: November 2, 2010Date of Patent: December 16, 2014Assignee: SK Innovation Co., Ltd.Inventors: Kyung Seok Noh, Jae Wook Ryu, Do Hyoun Kim, Gyung Rok Kim, Seung Woo Lee, Do Woan Kim, Sun Choi, Seung Hoon Oh, Byung Won Yoon, Bum Suk Chun

Patent number: 8834706Abstract: The present invention relates to a method for preparing lubricating base oils by using vacuum distilled deasphalted oil, and more specifically, to a method for preparing various kinds of lubricating base oils by distilling a distillate obtained from a solvent deasphalting (SDA) process under reduced pressure to obtain heavy deasphalted oil (H-DAO) and light deasphalted (Lt-DAO) and then treating the H-DAO and the Lt-DAO by catalytic reactions, respectively. According to the present invention, it is possible to obtain heavy lubricating base oil (150BS) of a high viscosity grade which can not be obtained by a known catalytic reaction and a lubricating base oil of group III by hydrogenation, in a high yield, and thus economical efficiency is excellent.Type: GrantFiled: June 3, 2011Date of Patent: September 16, 2014Assignee: SK Innovation Co., Ltd.Inventors: Kyung Seok Noh, Jae Wook Ryu, Do Hyoun Kim, Gyung Rok Kim, Seung Woo Lee, Do Woan Kim, Sun Choi, Seung Hoon Oh, Byung Won Yoon, Bum Suk Chun

Patent number: 8585889Abstract: A method of manufacturing high-quality naphthenic base oils comprising a high aromatic content and a large amount of impurities with a boiling point higher than that of gasoline. High-quality naphthenic base oil may be manufactured from light cycle oil (LCO) and slurry oil (SLO), which are inexpensive, and have a high aromatic content, a large amount of impurities, and which are effluents of a fluidized catalytic cracking (FCC) unit. The method also relates to the pretreatment process of a feedstock, where the amounts of impurities (sulfur, nitrogen, polynuclear aromatic compounds and various metals components) in the feedstock are reduced.Type: GrantFiled: August 7, 2008Date of Patent: November 19, 2013Assignee: SK Lubricants Co., Ltd.Inventors: Chang Kuk Kim, Jee Sun Shin, Kyung Seok Noh, Ju Hyun Lee, Byoung In Lee, Seung Woo Lee, Do Woan Kim, Sam Ryong Park, Seong Han Song, Gyung Rok Kim, Yoon Mang Hwang
