The present application discloses a turbulent fluidized bed reactor, apparatus and method for producing para-xylene from methanol and/or dimethyl ether and toluene to co-produce lower olefins, and producing para-xylene from methanol and/or dimethyl ether and toluene. In the process of co-producing lower olefins, by solving or improving the competition problem of MTO reaction and alkylation reaction, realizing a synergistic effect of MTO reaction and alkylation reaction, and controlling mass transfer and reaction, The competition between the alkylation reaction and the MTO reaction is adjusted and optimized to synergistically improve the conversion of toluene, the yield of para-xylene and the selectivity of lower olefins. The turbulent fluidized bed reactor includes a first reactor feed distributor and a plurality of second reactor feed distributors, the first reactor feed distributor and a plurality of second reactor feed distributors. The reactor feed distributors are sequentially arranged along the gas flow direction in the reaction region of the turbulent fluidized bed reactor. |
