The developments of methanol to olefins(MTO) and methanol to propylene(MTP) in process technology are summarized,the olefin separation technologies are introduced,the industrial application courses of MTO/MTP are collected and the future of MTO/MTP industry is forecasted. The process technologies of MTO and MTP have successfully been applied in commercial scale,and the total olefins capacity of the MTO/MTP projects which have already completed,are being built now and are planned at home has reached 15.19 Mt/a,which will take up more than 1/4 share of the total olefins capacity(ethylene and propylene). In future,it is needed to further improve the catalyst performance and olefins separation processes of MTO/MTP to enhance the yield of olefins and decrease the investment and the specific energy consumption of the plants.
