Patent number: 10927051Abstract: Disclosed is a method for preparing aromatic hydrocarbons, particularly relates to the preparation of the aromatic hydrocarbons by passing methanol and carbon monoxide through a reactor loaded with an acidic ZSM-5 molecular sieve catalyst containing no metal additive under reaction conditions. Compared with the prior art, the method provided by the present invention can improve and stabilize the selectivity to aromatic hydrocarbons, particularly BTX, by adding carbon monoxide in methanol aromatization, and also prolongs the single-pass life of the catalyst. The performance of an inactivated catalyst is not significantly degraded after repeated regenerations. Furthermore, the catalyst preparation process omits the step of adding a metal additive, so that not only the process is simplified, but also costs are greatly reduced, and environmental protection is facilitated.Type: GrantFiled: August 22, 2017Date of Patent: February 23, 2021Assignee: Dalian Institute of Chemical Physics, Chinese Academy of SciencesInventors: Youming Ni, Wenliang Zhu, Zhongmin Liu, Zhiyang Chen, Yong Liu, Hongchao Liu, Xiangang Ma, Shiping Liu
