APPARATUS AND METHOD FOR SYNTHESIS OF PARAXYLOL AND COMBINED SYNTHESIS OF LIGHT OLEFINS FROM METHANOL AND/OR DIMETHYL ETHER AND BENZENE Russian patent published in 2021 - IPC C07C15/08 B01J8/24 B01J8/26 C07C2/86 C07C1/24 

FIELD: chemistry.

SUBSTANCE: invention relates to a reactor with a fast fluidized bed for synthesis of paraxylol and combined synthesis of light olefins from methanol and/or dimethyl ether and benzene, wherein the bottom part of the reactor with the fast fluidized bed constitutes a reaction area and the top part of the reactor with the fast fluidized bed constitutes a diluted phase area. Said reactor with a fast fluidized bed is comprised of a body of the reactor, a distributor of the first reactor feed and multiple distributors of the second reactor feed, wherein both said distributor of the first reactor feed and said multiple distributors of the second reactor feed are located in sequence from the bottom up in the reaction area. Also said reactor with a fast fluidized bed is comprised of a first separator of solid and gas reactor phases, wherein said first separator of solid and gas reactor phases is located in the diluted phase area or outside of the reactor body. Said first separator of solid an gas reactor phases is equipped with an inlet for regenerated catalyst, an outlet for catalyst discharge from said first separator of solid an gas reactor phases is located in the bottom part of the reaction area and the gas outlet of said first separator of solid an gas reactor phases is located in the diluted phase area. The invention also relates to an apparatus and a method therefore.

EFFECT: use of the proposed invention allows improving conversion of benzene, yield of paraxylol and of light olefins.
