FLUIDIZED BED REACTOR, INSTALLATION AND METHOD OF PRODUCTION OF LIGHT OLEFINS Russian patent published in 2018 - IPC C07C1/20 C07C1/24 C07C11/02 B01J8/24 

Abstract RU 2649385 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a fluidized bed reactor for producing light olefins from oxygenated compounds and/or C4 hydrocarbons containing a reaction zone, equipped with a discharge pipe, which is located axially and divides the reaction zone into a fast reaction zone A inside the discharge pipe and a mixing zone B of the recycle stream outside the discharge pipe. Besides, two inlet ports for the catalyst are located in the reaction zone on the side wall of the reactor, wherein said reactor further comprises a catalyst outlet port and a gas distribution device, which has separate gas distribution openings corresponding to the fast reaction zone A and the mixing zone B of the recycle stream, respectively. Invention also relates to an apparatus and process for producing light olefins.

EFFECT: apparatus of the present invention can solve the problem of improving the ratio of the yield of light olefins, has great technical advantages and is applicable for industrial production of light olefins.
