ベンゼン並びにメタノール及び／又はジメヒルエーテルからパラキシレンを生産し低級オレフィンを併産する流動床反応器及び生産方法

Japanese Patent JP7035077

B2

Disclosed is a fluidized bed reactor for producing para-xylene and co-producing light olefins from benzene and methanol and/or dimethyl ether, comprising a first distributor and a second distributor. The first distributor is located at the bottom of the fluidized bed, and the second distributor is located at the downstream of the first distributor along a gas flow direction. Disclosed is a method for producing para-xylene and co-producing light olefins, mainly comprising the following steps: (1) a material stream A enters a reaction zone of the fluidized bed reactor from the first gas distributor; (2) a material stream B enters the reaction zone of the fluidized bed reactor from the second gas distributor; (3) a reactant contacts a catalyst in the reaction zone to generate a gas phase stream comprising para-xylene and light olefins. The present invention coordinates and optimizes the competition between a benzene alkylation reaction and an MTO reaction by controlling the mass transfer to facilitate a synergistic effect between two reactions, so that the conversion rate of benzene and the yield of para-xylene are greatly increased.
