A new generation of methanol-to-olefin industrialization technology (DMTO-II) developed by the National Engineering Laboratory of Methanol to Olefin, Dalian Institute of Chemical Physics, Chinese Academy of Sciences and with independent intellectual property rights has achieved major breakthroughs. On May 19, this industrialization test technology passed the 72-hour on-site assessment in Huaxian, Shaanxi Province. Experts believe that the data reached the expected indicators and the technology is advanced and feasible. It is recommended to promote industrialization and application as soon as possible.

The 50-ton / day DMTO-II technology industrialization test uses industrially-produced catalysts. The methanol feed starts on April 30, the methanol reaction by-product circulation conversion unit is fed on May 4, the single-pass conversion rate at 8:00 on May 12 and The selectivity of ethylene + propylene reached the expected index. After hundreds of hours of continuous and stable operation, a 72-hour on-site assessment and calibration was conducted from May 16 to May 19, and the results showed that the methanol conversion rate was close to 100%. Compared with DMTO technology, ethylene + propylene selectivity, methanol single Various technical indicators such as consumption and catalyst consumption have been greatly improved, marking a breakthrough in the development of a new generation of technology.
Experts commissioned by the China Petroleum and Chemical Industry Federation passed the on-site assessment and believed that the various technical indicators are advanced and reliable, which is further innovation on the basis of DMTO technology, and is another major progress made by China's coal-to-olefin technology, which gives full play to the advantages of coal resources. It is of great strategic significance to develop China's new methanol-to-olefin coal chemical industry.
