Abstract

This present invention relates to a reaction device for preparing light olefins from methanol and/or dimethyl ether, and more specifically relates to a reaction device for preparing light olefins from methanol and/or dimethyl ether, which mainly comprises a dense phase fluidized bed reactor (2), a cyclone separator (3), a stripper (5), a lift pipe (7), a dense phase fluidized bed regenerator (10), a cyclone separator (11), a stripper (13), and a lift pipe (15), wherein the dense phase fluidized bed reactor (2) is separated into n (n?2) secondary reaction zones by a material flow controller (17), and the dense phase fluidized bed regenerator (10) is separated into m (m?2) secondary regeneration zones by the material flow controller (17). The use of the reaction device of this present invention solves the problems in the prior art that the distribution of carbon deposition on a catalyst is non-uniform and the selectivity for the light olefins is relatively low.
