My own large-scale methanol technology matures

The technology and quality of the low-pressure methanol synthesis technology independently developed by China are improving and have matured. This is the news that the reporter learned from yesterday’s seminar on methanol synthesis technology exchange and promotion.

In recent years, under the guidance of technological innovation guidelines and the implementation of energy substitution strategy, the domestic methanol synthesis technology has made new development. The main performance is as follows: First, the domestic single-series large-scale methanol equipment technology has developed rapidly. China East China University of Science and Technology, Nanjing Guochang Chemical Technology Co., Ltd., Hangzhou Linda Chemical Engineering Technology Co., Ltd. and other units have done a lot of innovative work in the design of methanol large-scale synthesis towers, and have a number of independent and innovative advanced technologies for the production of methanol in China. Large-scale establishment of the foundation. The second is the rapid development of efficient methanol synthesis catalyst technology. Since our country successfully developed copper-based catalysts in the 1970s, we have never stopped the research and development of methanol catalysts, and new types of methanol synthesis catalysts with better low-temperature activity, higher space-time yield, and high stability have appeared. The new methanol synthesis catalysts successfully developed by the Research Institute of Nanhua Group and the Southwest Research Institute of Chemical Industry have continuously improved their performance levels, gradually approaching and even surpassing the international advanced level. The successful development and promotion of these new methanol synthesis core technologies will certainly provide strong technical support for the development of China's methanol industry and the realization of energy conservation and emission reduction.

Tan Zhuzhou, honorary president of the China Petroleum and Chemical Industry Association, pointed out that for a long time China's methanol plant has been dominated by small-scale installations, and currently there are only a few units with a scale of 200,000 tons/year or more. Therefore, methanol companies must vigorously develop the popularization and application of large-scale low-pressure methanol synthesis technology developed independently in China. Especially at present, the situation of energy-saving and emission-reduction in China is very serious. Methanol companies must vigorously carry out technological transformation of energy-saving and emission-reduction, and actively adopt large-scale, low-pressure methanol synthesis domestic technologies for energy conservation and environmental protection.
