The research, development, and production of catalysts for methanol synthesis in China have a history of over 40 years, evolving from the initial Zn-Cr and Cu-Zn-Cr systems to the current Cu-Zn-Al systems. As one of the earliest institutions in China to develop catalysts for synthetic methanol, the Research Institute of Nanhua Group has introduced catalysts suitable for various methanol production processes. The introduction of these products reflects the progress made in the development of synthetic methanol catalysts in our country. The high-pressure methanol synthesis process has high energy consumption. At present, there are very few manufacturers, and the development of high-pressure methanol synthesis catalysts to go with them has come to a standstill, remaining at the original level. Although no new types have emerged, the C301 catalyst remains the best high-pressure methanol synthesis catalyst available in China today. The development of ligand alcohol industry has driven the progress of ligand alcohol catalysts. Currently, there are a wide variety of ligand-catalyzed catalysts available on the market, but most of them imitate the C207 type of catalyst, with no significant qualitative improvement. Moreover, many small polyol plants use raw materials of poor quality with high sulfur content, making it difficult for even good catalysts to function effectively. If the issue of raw gas purification is resolved, the NC501 catalyst, which exhibits superior performance metrics across all aspects, can fully replace C207. Due to the low energy consumption of low-pressure methanol synthesis plants, many manufacturers are currently planning to build such plants. Many domestic institutions are paying considerable attention to catalysts for low-pressure methanol synthesis, which will contribute to the development of such catalysts in China. The development trend for catalysts in low-pressure methanol synthesis remains high activity and high selectivity. Looking at domestic catalysts for methanol synthesis, after decades of development, improvement, and practical application, they have now reached a considerable level of performance. The development trend of methanol catalysts remains toward lower temperatures, lower pressures, higher activity, higher selectivity, greater thermal stability, and higher mechanical strength. Therefore, the manufacturers of methanol catalysts should continue to develop catalysts with high activity, high selectivity, and long lifespan based on the performance of existing catalysts, while also creating methanol catalysts that meet the requirements of different processes.
