A method methanol byproduct aromatics and olefins and means

The present invention discloses a method and apparatus aromatics methanol byproduct and light olefins. The prior art to solve the aromatics product low yield of dry gas and liquefied gas such problems. Wherein the methanol feedstock is preheated to 350-500 deg.] C into the riser reactor, the reaction was carried out in a riser reactor with a catalyst, wherein the catalyst is Ga, Zn, P, and Ag-modified ZSM-5 / SAPO-34 catalyst, the contact time of the feedstock and the catalyst the methanol was 0.8-4.0 seconds, to enhance the reaction product into the tube reactor and then a deep catalytic reactor (such as fluidized bed, moving bed or fixed bed reactor) to react, the depth of the catalytic reactor the reaction C2-C5 alkane product returned to the catalytic reactor-back depth of refining, the apparatus further product as a product.
