Publication number: 20230242806Abstract: A process for the conversion of methanol to olefins includes the steps of passing a feedstock comprising methanol to a fluidized bed reactor in contact with a catalyst to produce an olefin product, wherein the process at least partially deactivates the catalyst to form an at least partially deactivated catalyst; and passing spent catalyst from said at least partially deactivated catalyst to a regenerator for regeneration thereby forming regenerated catalyst and returning activated catalyst from said regenerated catalyst to said reactor via a regenerated catalyst line. An oxygen volume content in the gas-phase component at the outlet of the regenerated catalyst pipeline is controlled to be less than 0.1 percent, preferably less than 0.05% and more preferably less than 0.01% on the regenerated catalyst pipeline.Type: ApplicationFiled: July 2, 2021Publication date: August 3, 2023Applicant: SHANGHAI RESEARCH INSTITUTE OF PETROCHEMICAL TECHNOLOGY, SINOPECInventors: Yingcheng LI, Xinning BAO, Weidong ZHANG, Ou SHA, Xinyue WU, Jun JIN
