BOILING LAYER REACTOR AND METHOD FOR PRODUCING PARA-XYLOL AND CO-PRODUCTION OF LOWEST OLEFINS FROM BENZENE AND METHANOL AND / OR DIMETHYL ETHER Russian patent published in 2021 - IPC B01J8/24 C07C15/08 C07C2/64 

FIELD: oil industry.

SUBSTANCE: invention relates to fluidized bed reactors and their use for the production of para-xylene and the combined production of lower olefins from benzene and methanol and / or dimethyl ether. Described is a reactor comprising a first and a second distributor through which material streams A and B enter the reactor, the first distributor being located in the lower part of the fluidized bed, and the second being located in at least one zone of the gas flow after the first distributor; moreover, the second distributor contains an inlet pipe, a microporous pipe and an inlet annular pipe; the inlet pipe is connected to a gas passage of the microporous pipe, the gas being supplied through the inlet pipe outside the fluidized bed into the microporous pipe in the fluidized bed; the inlet annular pipe is connected to the gas passage of the inlet pipe, and the inlet annular pipe is located in a plane perpendicular to the direction of gas flow from the first distributor; the microporous pipe is located on the annular inlet pipe and perpendicular to the plane of the inlet annular pipe; stream A contains benzene or methanol and / or dimethyl ether and benzene; stream B contains methanol and / or dimethyl ether.

EFFECT: increased degree of conversion of benzene and the yield of para-xylene.
