REACTOR WITH A TURBULENT FLUIDIZED BED, APPARATUS AND METHOD, WHICH USE AN OXYGEN-CONTAINING COMPOUND FOR PRODUCING PROPENE AND C4 HYDROCARBONS Russian patent published in 2020 - IPC C07C11/04 C07C11/06 C07C1/20 B01J8/26 

FIELD: technological processes.

SUBSTANCE: present invention relates to a reactor with a turbulent fluidized bed, a device and a method for producing propylene and C4 hydrocarbons from oxygen-containing compounds. Proposed device comprises reactor with turbulent fluidized bed and regenerator with fluidized bed for regeneration of catalyst. Disclosed method comprises: a) feeding raw material containing oxygen-containing compounds from n reactor feed distributors to reaction zone of reactor with turbulent fluidized bed and bringing raw material into contact with catalyst to form stream containing target product and spent catalyst containing carbon; b) directing the stream discharged from the reactor with the turbulent fluidized bed and containing the end product into a product separation system to obtain propylene, C4 hydrocarbons, light fractions, etc. after separation, recovery of 70 wt% or more of light fractions from the reactor feed distributor in the lowest part of the reactor with the turbulent fluidized bed into the reaction zone of the reactor with a turbulent fluidized bed and reaction of ethylene and oxygen-containing compounds with alkylation reaction in the presence of a catalyst to obtain products in form of propylene, etc.

EFFECT: method and device according to present invention increase rate of alkylation of ethylene, wherein production capacity of reactor per unit volume is high.
