Patent number: 10781148Abstract: A method of preparing butadiene and a device for preparing the same. The method includes passing reaction raw materials containing butene, oxygen, steam, and a diluent gas through an oxidative dehydrogenation reactor, and oxidative dehydrogenation is performed therein to produce a reaction product separating water from the reaction product condensing hydrocarbons to produce a crude hydrocarbon mixture; and separating butadiene from the crude hydrocarbon mixture, where a gas containing n-butane remaining after the butadiene is separated is fed into the oxidative dehydrogenation reactor, and butane is used as a diluent gas. Because butane is used as a diluent gas, a C4 mixture and gas products may be easily separated through cooling and condensation processes. Thus, the method may increase productivity while reducing energy consumption and raw material costs, thereby improving economic efficiency.Type: GrantFiled: December 18, 2017Date of Patent: September 22, 2020Assignee: LG CHEM, LTD.Inventors: Mi Kyung Kim, Jae Ik Lee, Eun Kyo Kim, Jeong Seok Lee, Young Chang Byun, A Ra Cho

Patent number: 6632772Abstract: A method of coating a catalyst to a support for use in acrolein oxidation reaction. Metallic salt components of the catalyst including molybdate, vanadate and tungstate are dissolved in a liquid to form a suspension of particles of the catalyst. The precipitation of the catalyst particles is controlled by homogenizing the catalyst particles suspended in the liquid. The phase separation between the catalyst particles and the liquid can be substantially slowed down by the homogenization. Then the catalyst is coated on an inert support by applying the suspension of the catalyst particles to the support. In the suspension, the total weight of water is about 0.8 to about 5 times of the total weight of the metallic salts in the catalyst. This method of preparing suspension minimizes the amount of the liquid required to dissolve the metallic salts, which reduces the amount of time and energy to be used in evaporating the liquid from the suspension.Type: GrantFiled: December 22, 2000Date of Patent: October 14, 2003Assignee: LG Chemical, Ltd.Inventors: Won-Ho Lee, Kyung-Hwa Kang, Dong-Hyun Ko, Young-Chang Byun

Patent number: 6384275Abstract: A method of producing acrylic acid using a catalyst for acrolein oxidation reaction. Metallic salt components of the catalyst including molybdate, vanadate and tungstate are dissolved in water. An additional metallic salt component of the catalyst is added to the aqueous solution of the salts to form a suspension of the catalyst. In the suspension, the total weight of water is about 0.8 to about 5 times of the total weight of the metallic salts in the catalyst. This method of preparing suspension minimizes the amount of water required to dissolve the metallic salts, which reduces the amount of time and energy to be used in evaporating water from the suspension in the following step of obtaining catalyst. Additionally, in obtaining catalyst from the suspension prepared by this method, it is possible to avoid the deterioration of the catalytic performance since less heat is required to evaporate the water. Disclosed also is a method of producing a carrier-retained catalyst.Type: GrantFiled: December 22, 2000Date of Patent: May 7, 2002Assignee: LG Chem, Ltd.Inventors: Won-Ho Lee, Kyung-Hwa Kang, Dong-Hyun Ko, Young-Chang Byun
