摘要： The application provides a catalyst for producing ethylene and propylene from methanol and/or dimethyl ether, and a preparation and application thereof. In the present application, a molecular sieve catalyst co-modified by rare earth metals and silanization is utilized. First, the material containing methanol and/or dimethyl ether reacts on the catalyst to generate hydrocarbons. The hydrocarbons are separated into a C1-C5 component and a C6+ component. Then the C6+ component is recycled to the feeding port and fed into the reactor after mixing with methanol and/or dimethyl ether. The above steps are repeated, to finally generate C1-C5 products, in which the selectivity for ethylene and propylene can reach more than 90 wt % in the C1-C5 component, so that the maximal yield can be achieved in the production of ethylene and propylene from methanol and/or dimethyl ether.
