Patent number: 11305265Abstract: An aromatization catalyst and preparation process and use thereof is set forth. The catalyst comprises an inorganic oxide and a modified Ga-ZSM-5 zeolite, which comprises a modified ZSM-5 zeolite with a hierarchical macro-meso-microporosity and gallium deposited in channels of and/or on surfaces of the modified ZSM-5 zeolite. The hierarchical porosity of the modified ZSM-5 zeolite in the catalyst can reduce diffusion resistance of products during the aromatization reaction, thereby retarding carbon depositing rate and substantially improving catalytic activity, aromatic hydrocarbon selectivity, stability and lifetime of the catalyst. When being used in aromatization of propane, the catalyst exhibits a high stability, a lifetime of more than 320 hours, and a selectivity to aromatic hydrocarbons of up to 73.3 wt. %.Type: GrantFiled: August 14, 2020Date of Patent: April 19, 2022Assignees: Institute of Coal Chemistry, Chinese Academy of Sciences, Shanxi Lu'an Mining (Group) Co., Ltd.Inventors: Weibin Fan, Dezhi Shi, Huaqing Zhu, Mei Dong, Jianguo Wang, Zhiwei Wu, Weiyong Jiao, Junyi Liu, Dongfei Wang, Jinbo Li, Yanbin Cui, Yibo Zhang

Patent number: 11084772Abstract: The disclosure relates to a process for continuously producing polyoxymethylene dimethyl ethers at low temperature, pertains to the technical field of polyoxymethylene dimethyl ether preparation processes, and solves the technical problem of continuous production of polyoxymethylene dimethyl ether. A membrane separation element with precisely controlled pores in membrane is used to realize a direct separation of the feedstocks from the catalyst within the reactor, and effectively reduce the permeation resistance of the separation membrane tube. By oppositely switching the flowing direction of liquid reaction materials, the adhesion of the catalyst to the separation membrane tube is inhibited, and some particles stuck in separation membrane tube are removed, which ensures the continuous operation of the reaction process and allows a molecular sieve catalyst to exhibit its advantage of long catalytic life.Type: GrantFiled: April 28, 2020Date of Patent: August 10, 2021Assignees: Institute of Coal Chemistry, Chinese Academy of Sciences, Shanxi Lu'an Mining (Group) Co., Ltd.Inventors: Weibin Fan, Guofu Wang, Jiaqi Guo, Jianguo Wang, Mei Dong, Pengfei Wang, Youliang Cen, Yaning Xiao, Dongfei Wang, Shoujing Sun, Weilin Wang, Juncai Zhang, Min Zhang, Yunhong Li

Patent number: 10844287Abstract: The present invention provides a method for preparing gasoline and aromatics by using Fischer-Tropsch synthesis exhaust. The method includes conducting an olefin conversion reaction on Fischer-Tropsch synthesis exhaust under the action of a first molecular sieve catalyst. A first refrigeration or cooling is conducted on an obtained product to obtain ultralow sulfur-containing gasoline and first-stage reaction gas. An alkaline aromatization reaction is conducted on the first-stage reaction gas under the action of a second molecular sieve catalyst. A second refrigeration or cooling is conducted on an obtained product to obtain aromatics. After the olefin conversion reaction, a gasoline component is separated and residual alkanes enter a second-stage fluidized bed reactor for the alkane aromatization reaction to produce aromatics.Type: GrantFiled: November 13, 2019Date of Patent: November 24, 2020Assignee: INSTITUTE OF COAL CHEMISTRY, CHINESE ACADEMY OF SCIENCESInventors: Weibin Fan, Jianguo Wang, Zhiwei Wu, Mei Dong, Zhangfeng Qin, Huaqing Zhu, Junfen Li, Weiyong Jiao -
