GAS DISTRIBUTOR WITH BOILING BED, REACTOR WITH GAS DISTRIBUTOR WITH BOILING BED AND METHOD OF PRODUCING PARA-XYLENE AND COMBINED PRODUCTION OF LOWER OLEFINS Russian patent published in 2020 - IPC B01J8/18 

FIELD: oil, gas and coke-chemical industry.

SUBSTANCE: group of inventions relates to a gas distributor in a fluidised bed, a reactor comprising such a distributor, and a method of producing para-xylene and co-producing lower olefins. Distributor comprises a first distributor located in the lower part of the fluidised bed and a second distributor disposed in at least one region of the gas stream on the path of movement thereof from the first distributor, wherein the second distributor comprises an inlet pipe, a microporous pipe and an inlet annular pipe, wherein the side and rear surfaces of the microporous pipe have a homogeneous microporous structure and one end of the microporous pipe is connected to the inlet annular pipe, and its second end is closed.

EFFECT: distributor allows to regulate mass transfer by means of distribution of flows of various raw materials in different zones in system of raw supply of raw material with a wide difference in reaction rates of raw materials, which ensures coordination and optimization of the system for combined supply of raw material and improved output of the reaction.
