[Ten years of development of chemical equipment] 780-2017 Shanxi Coal Chemical Institute's 100-ton methanol to aromatics (MTA) technology
Thread Content
Looking at the great development of chemical equipment in the past ten years, I praise the prosperity of China and wish everyone a happy new year. May your family be safe and healthy. It will be more lively and exciting with everyone's participation. Everyone is welcome to participate in more forum exchanges and discussions------------------------------------------------- In October 2017, Shanxi Institute of Coal Chemistry, Chinese Academy of Sciences, Coal Transformation* * The methanol conversion team of the Key Laboratory successfully completed a 100-ton methanol to aromatics (MTA) pilot test at the Xiaodian pilot base in Taiyuan City. This test was conducted on a self-developed 100-ton methanol-to-aromatics pilot plant. After installation, commissioning and equipment optimization of the device, the test was successfully started in one go. During the test, not only the entire production process was opened up, but also the independently developed catalyst and process conditions were verified and optimized, and operating conditions such as inlet and outlet flow, temperature and pressure were automatically controlled. Up to now, the device has achieved full load and stable continuous operation for 500 hours, producing qualified aromatics. All technical indicators have reached and exceeded the same domestic technology (methanol conversion rate 100%, liquid hydrocarbon yield 31%, aromatic hydrocarbon selectivity 83%). Methanol conversion to aromatics is a process that uses methanol as raw material and converts it on a molecular sieve catalyst to produce aromatic products. It is a process route that effectively uses coal or natural gas to replace petroleum resources to produce benzene, toluene, xylene and other aromatic products. It is of great significance for alleviating the shortage of aromatic resources and extending the coal chemical and natural gas chemical industry chains.
The Methanol to Aromatics (MTA) technology of the Shanxi Coal Chemical Institute is supported by the Chinese Academy of Sciences’ strategic leading science and technology project “Key Technologies and Demonstrations for Clean and Efficient Cascade Utilization of Low-Rank Coal” and related enterprises. It adopts a self-developed two-stage continuous flow fixed-bed reaction process. The research team has gone through long-term persistence and unremitting research, and carried out work on reaction mechanism, catalyst design and process optimization around methanol directional conversion technology. In Chem. Soc. Rev., J. Catal., ACS Catal., Chem. Commun., Green Chem., etc. have published more than 20 papers. On this basis, they have developed new catalysts and supporting process routes for producing high value-added aromatics from coal-based methanol, achieving breakthroughs in aromatic product selectivity, reaction operation stability, and technical scale. The successful completion of the 100-ton methanol-to-aromatics pilot plant and the stable operation of the device further promoted the industrialization process of this technology.
