FLUIDISED BED DEVICE AND A METHOD OF PRODUCING PARA-XYLENE AND CO-PRODUCING LOWER OLEFINS FROM METHANOL AND/OR DIMETHYL ETHER AND BENZENE Russian patent published in 2021 - IPC B01J8/18 

FIELD: chemistry.

SUBSTANCE: invention relates to a device and a method of producing para-xylene (PX) and combined production of lower olefins. Disclosed is a reactor with a turbulent fluidised bed for producing para-xylene and co-producing lower olefins from methanol and/or dimethyl ether and benzene, wherein said reactor with a turbulent fluidised bed comprises a first reactor feedstock distributor and a plurality of second feed distributors for the reactor, and a first reactor feedstock distributor and a plurality of second reactor feedstock distributors are arranged in series bottom-up in the reaction zone of the turbulent fluidised bed reactor; wherein number of distributors of second raw material for reactor ranges from 2 to 10, wherein reactor with turbulent fluidised bed includes first solid-phase separator of reactor and gas phase, wherein the first solid phase separator of the reactor is located in the diluted phase or outside the reactor housing, wherein first solid and gas phases separator of reactor is provided with opening for regenerated catalyst supply, wherein catalyst discharge hole from first solid phase separator and gas phase reactor is located in lower part of reaction zone, and gas outlet hole from first solid phase separator and gas phase reactor is located in diluted phase area.

EFFECT: technical result is increased degree of conversion of benzene, output of para-xylene and yield of lower olefins.
