Fluidized bed device for coupling naphtha and methanol to prepare aromatics and co-produce olefins and its application method

A fluidized bed device for coupling naphtha and methanol to prepare aromatics and co-produce olefins, comprising a naphtha and methanol coupled aromatization reactor, a regenerator, and a light hydrocarbon aromatization reactor;

• wherein the naphtha and methanol coupled aromatization reactor is connected to the regenerator via a first spent catalyst delivery pipe;
• the regenerator is connected to the naphtha and methanol coupled aromatization reactor via a regenerated catalyst delivery pipe;
• a naphtha and methanol coupled aromatization reactor distributor is provided in the naphtha and methanol coupled aromatization reactor;
• the naphtha and methanol coupled aromatization reactor distributor comprises n sub-distributors, sequentially arranged from bottom to top as the 1st sub-distributor to the nth sub-distributor, wherein 2≤n≤10;
• the 1st sub-distributor is configured to introduce a naphtha feedstock;
• the 2nd to nth sub-distributors are configured to introduce a methanol feedstock;
• the light hydrocarbon aromatization reactor comprises a riser reactor, and the riser reactor is connected to a bed reactor;
• the regenerator is connected to the riser reactor via a second regenerated catalyst slide valve;
• the bed reactor is connected to the regenerator via a second spent catalyst delivery pipe.
