Title:
COKE REGULATION AND CONTROL REACTOR, DEVICE AND METHOD FOR PREPARING LIGHT OLEFIN FROM OXYGEN-CONTAINING COMPOUND
Document Type and Number:
WIPO Patent Application WO/2022/077457
Kind Code:
A1
Abstract:
A coke regulation and control reactor, a device and a method for preparing a light olefin from an oxygen-containing compound. The coke regulation and control reactor comprises a coke regulation and control reactor housing, a reaction region I, and a coke regulation and control catalyst settling region; a cross-sectional area of any position in the reaction region I is less than a cross-sectional area of any position in the coke regulation and control catalyst settling region; n baffles are provided along the vertical direction within the reaction region I; the n baffles divide the reaction region I into m reaction region I sub-regions; and a catalyst flow hole is provided on the baffles, such that a catalyst flows within the reaction region I by using a preset means. The catalyst storage in the coke regulation and control reactor can be automatically adjusted, and an average retention time of a catalyst in the coke regulation and control reactor can be controlled by changing a process operating condition, thereby controlling the coke content in the catalyst.
