Title:
FLUIDIZED BED APPARATUS AND METHOD FOR PREPARING PARA-XYLENE CO-PRODUCED LOW-CARBON OLEFIN FROM METHANOL AND/OR DIMETHYL ETHER AND TOLUENE
Document Type and Number:
WIPO Patent Application WO/2018/196361
Kind Code:
A1
Abstract:
Disclosed are a turbulent fluidized bed reactor, apparatus and method for preparing para-xylene co-produced low-carbon olefin from methanol and/or dimethyl ether and toluene, resolving or improving the competition problem between an MTO reaction and an alkylation reaction during the process of producing para-xylene co-produced low-carbon olefin from methanol and/or dimethyl ether and toluene, and achieving a synergistic effect of the MTO reaction and the alkylation reaction. By controlling the mass transfer and reaction, competition between the MTO reaction and the alkylation reaction is coordinated and optimized to facilitate a synergistic effect of the two reactions, so that the conversion rate of toluene, the yield of para-xylene, and the selectivity of low-carbon olefin are increased. The turbulent fluidized bed reactor comprises a first reactor feeding distributor and a plurality of second reactor feeding distributors; the first reactor feeding distributor and the plurality of second reactor feeding distributions are sequentially arranged along a gas flow direction in a reaction zone of the turbulent fluidized bed reactor.
