In the recent years, the price of crude oil increases year by year, which result in  the high cost of the ethylene and propylene. The international company in global is hunting new materials and technology. The reserve of coal is relative abundant in China, while that of natural gas is deficient and petroleum is lacking. MTO process could release the lack of petroleum and diversify the raw materials of the production of light olefins.

DMTO process shows evident technoeconomics advantage compared with the tubular furnace cracking of naphtha with high oil price. It will benefit to decrease the reliability of light oil in China, and to lighten the pressure brought by the less oil supply. At the same time, this technology can combined the Coal Chemical industry and Petrol Chemical industry.
