Patent number: 11524282Abstract: A regeneration method for a benzene alkylation solid acid catalyst, comprising: purging the solid acid catalyst in a reactor with a gas; continuously injecting n-hexane at a feed port of the reactor and heating the n-hexane to wash the solid acid catalyst, and discharging the n-hexane entraining benzene alkylation reaction residues from a discharge port of the reactor; and stopping injecting n-hexane, cleaning off a liquid in the reactor by purging with the gas, and cooling the reactor. In the regeneration method of the present disclosure, the regeneration liquid used is n-hexane, which can increase the solubility of the residues in channels and enhance the regeneration effect. Meanwhile, permanent damage to the channel structure of the catalyst caused by carbon burning regeneration can be avoided, thereby prolonging the lifetime of the catalyst.Type: GrantFiled: June 11, 2019Date of Patent: December 13, 2022Assignee: Inner Mongolia Yitai Coal-based New Materials Research Institute Co., Ltd.Inventors: Zhen Qian, Jingwei Wu, Juncheng Li, Xiaolong Zhang, Hongcheng Cao, Yuan Gao, Xueting Wu

Patent number: 11370732Abstract: The present disclosure provides a method of separating ?-olefin by a simulated moving bed. The method comprises using a coal-based Fischer-Tropsch synthetic oil as a raw material to obtain a target olefin having a carbon number N within a range from 9 to 18, wherein the raw material is subjected to treatment steps including pretreatment, fraction cutting, alkane-alkene separation, and isomer separation, thereby obtaining a high purity ?-olefin product. As compared to conventional rectification and extraction processes, the product obtained by the method of the present disclosure has advantages of higher purity, higher yield, lower energy consumption, and significantly reduced production cost.Type: GrantFiled: June 14, 2019Date of Patent: June 28, 2022Assignee: INNER MONGOLIA YITAI COAL-BASED NEW MATERIALS RESEARCH INSTITUTE CO., LTD.Inventors: Juncheng Li, Zhen Qian, Jingwei Wu, Xiaolong Zhang, Qinge Jian, Yuan Gao, Xueting Wu, Haoting Chen
