Advances and application prospect of coal-based methanol-to-olefins
Liu Gong · Clean Coal Technology · 2011
The technology of preparing methanol from synthesis gas,as well as preparing polyolefin and other downstream products of olefins is mature.The key technology of preparing light olefins production from methanol also is the bottleneck as the coal to light olefins route.Representative process such as the light olefins from methanol process(MTO and MTP)at home and abroad was introduced,and compared those two processes and their application efficiency.The analysis show that the MTO process is suitable for the large olefin and requiring approximate ration of propylene and ethylene users,the MTP process is mostly suitable for pure propylene and not requiring or requiring little ethylene users.
