Title:
METHOD FOR PRODUCING LIGHT OLEFIN FROM OXYGEN-CONTAINING COMPOUND
Document Type and Number:
WIPO Patent Application WO/2021/180150
Kind Code:
A1
Abstract:
Disclosed is a method for producing a light olefin from an oxygen-containing compound, the method comprising the step of bringing a raw material comprising an oxygen-containing compound into contact with a molecular sieve catalyst in a fluidized bed reaction zone to produce products containing ethylene and/or propylene under effective conditions, wherein the effective conditions involve: in the fluidized bed reaction zone, on the basis of the mass of the molecular sieve in the catalyst, controlling the proportion of the mass of catalysts with various amounts of carbon deposit in the total catalyst mass in the fluidized bed reaction zone.
