Patent number: 9062262Abstract: Disclosed is a method of recovering 1,3-butadiene from a C4 stream containing butane, isobutane, 2-butene, 1-butene, isobutene, butadiene and acetylene. The process of recovering highly pure 1,3-butadiene includes acetylene conversion for selectively converting acetylene through liquid-phase hydrogenation, so that the acetylene content is decreased to 70 wt ppm or less, and 1,3-butadiene extraction using an extractive distillation column, a pre-separator, a solvent stripping column, a solvent recovery column, and a purification column. Through the acetylene conversion, the concentration of vinylacetylene is decreased to 70 wt ppm or less, after which 1,3-butadiene is recovered using only one extractive distillation column, thereby considerably decreasing the degree of utility and the loss of streams in the course of extraction. The number of units necessary for the process is decreased, thus remarkably reducing the time during which impurities can accumulate in a processing unit.Type: GrantFiled: July 18, 2008Date of Patent: June 23, 2015Assignee: SK INNOVATION CO., LTD.Inventors: Hee Du Lee, Kyung Jong Oh, Min Su Ko, Min Gyoo Park, Seong Jun Lee, Yoon Jae Yim, Seung Hoon Oh, Tae Jin Kim, Yong Seung Kim, Deuk Soo Park, Hong Chan Kim

Patent number: 9056308Abstract: Disclosed are a molecular sieve catalyst and a preparation method thereof to produce light olefins from cracking naphtha catalytically in severe environments of high temperature and high moisture. In detail, the catalyst is prepared by spray-drying and calcining the mixed slurry, in which 0.01˜5.0 wt % of MnO2 and 1˜15 wt % of P2O5 are simultaneously imbedded in catalyst which consists of zeolite, clay and inorganic complex. According to the present invention, the method that manganese and phosphate are imbedded simultaneously in zeolite and inorganic complex is used to increases thermal-stability of obtained spherical catalyst, and increase olefin yield of cracking hydrocarbon such as naphtha by protecting acid-site of zeolite. To synthesize the required catalyst, the important procedures are mixing ratio and mixing sequence of Mn, P, zeolite, and inorganic complex.Type: GrantFiled: January 30, 2014Date of Patent: June 16, 2015Assignee: SK INNOVATION CO., LTD.Inventors: Dae Hyun Choo, Hong Chan Kim, Suk Joon Kim, Ji Min Kim, Tae Jin Kim, Sun Choi, Seung Hoon Oh, Yong Seung Kim, Deuk Soo Park, Yong Ki Park, Chul Wee Lee, Hee Young Kim, Won Choon Choi, Na Young Kang, Bu Sub Song

Patent number: 7718840Abstract: Disclosed is a process for producing light olefins from hydrocarbon feedstock. The process is characterized in that a porous molecular sieve catalyst consisting of a product obtained by evaporating water from a raw material mixture comprising a molecular sieve with a framework of Si—OH—Al— groups, a water-insoluble metal salt, and a phosphate compound, is used to produce light olefins, particularly ethylene and propylene, from hydrocarbon, while maintaining excellent selectivity to light olefins. According to the process, by the use of a specific catalyst with hydrothermal stability, light olefins can be selectively produced in high yield with high selectivity from hydrocarbon feedstock, particularly full-range naphtha. In particular, the process can maintain higher cracking activity than the reaction temperature required in the prior thermal cracking process for the production of light olefins, and thus, can produce light olefins with high selectivity and conversion from hydrocarbon feedstock.Type: GrantFiled: June 27, 2006Date of Patent: May 18, 2010Assignees: SK Energy Co., Ltd., Korea Research Institute of Chemical TechnologyInventors: Sun Choi, Yong Seung Kim, Deuk Soo Park, Suk Joon Kim, Il Mo Yang, Hee Young Kim, Yong Ki Park, Chul Wee Lee, Won Choon Choi, Kwang An Ko, Na Young Kang
