Patent number: 9579637Abstract: The present invention relates to a SAPO-34 molecular sieve having both micropores and mesopores and synthesis method thereof. The mesopore diameter in the molecular sieve is in a range of 2-10 nm and the mesopore volume thereof is 0.03-0.3 cm3/g. Triethylamine is used as a template agent and the pore size modifiers are added to the synthesis gel at the same time in the synthesis process, thereby the prepared molecular sieve crystals have mesopore distribution besides micropores. The SAPO-34 molecular sieve synthesized in the present invention can be used as catalysts for conversion of oxygen-containing compounds to lower olefins.Type: GrantFiled: June 21, 2013Date of Patent: February 28, 2017Assignee: Dalian Institute of Chemical Physics, Chinese Academy of SciencesInventors: Lei Xu, Peng Tian, Zhongmin Liu, Lixin Yang, Shuanghe Meng, Changqing He, Cuiyu Yuan, Yue Qi

Patent number: 9440226Abstract: The present invention provides a method for preparing methyl acetate, in which a feed gas containing an organic amine, dimethyl ether, carbon monoxide and optional hydrogen gas goes through a reactor loaded with a H-type mordenite catalyst, to produce methyl acetate; wherein said H-type mordenite catalyst is a H-type mordenite catalyst with adsorption of an organic amine. The method in the present invention improves the catalyst stability and prolongs the catalyst life, by using the H-type mordenite catalyst with adsorption of an organic amine as the catalyst and adding the organic amine in the feed gas to replenish the organic amine desorbed from the catalyst during the reaction.Type: GrantFiled: January 28, 2014Date of Patent: September 13, 2016Assignee: DALIAN INSTITUTE OF CHEMICAL PHYSICS, CHINESE ACADEMY OF SCIENCESInventors: Youming Ni, Wenliang Zhu, Hongchao Liu, Yong Liu, Zhongmin Liu, Shuanghe Meng, Lina Li, Shiping Liu, Hui Zhou
