Abstract

The invention discloses a methanol conversion reactor, a reaction system and a methanol conversion method. The reactor comprises a housing 2, a feed gas inlet 4 arranged at the top of the housing 2, a reaction gas outlet 1 arranged at the bottom of the housing 2, a catalyst inlet arranged in a side face of the top of the housing 2 and a spent agent outlet arranged in a side face of the bottom of the housing 2, wherein multiple catalyst support plates 3 which slantly extend to pass through cross section of the housing 2, are spaced from each other and are used for making a catalyst to slip down from the top of the housing 2 to the bottom of the housing 2 are also arranged inside the housing 2; lower ends of the catalyst support plates 3 are provided with gaps used as slipping channels of the catalyst; and the catalyst support plates 3 are provided with multiple small holes used for allowing reaction gas to flow downwards. According to the invention, contact efficiency can be raised, side reaction is reduced, and conversion rate of raw materials and selectivity of a target product are enhanced.

Description

technical field [0001] The invention relates to a methanol conversion reactor, a reaction system and a methanol conversion method. Specifically, it relates to a gas-solid co-current circulating moving bed reactor, a methanol conversion reaction system containing the reactor, and a method for producing light olefins or gasoline by using the reaction system for methanol conversion. Background technique [0002] The conversion of methanol to low-carbon olefins or gasoline is an important "carbon one" chemical process, which can be used to solve the use of methanol and increase low-carbon olefins or gasoline products. The methanol conversion reaction is mostly a heterogeneous catalytic reaction process, and the reaction on the catalyst is a complex reaction mixed with parallel and sequential reactions. Different reactions have different requirements for the activity of the catalyst and the product distribution is also different. Therefore, in order to obtain the target product ...
