Progresses in MTO and MTP Process Technology and Industrial Application

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.
