New synthetic methanol catalysts are widely used in methanol plants of various processes, including medium and low pressure processes such as Lurgi process and ICI process. Due to the great improvement of the preparation process of the catalyst, the performance of the catalyst has been greatly improved, which is mainly manifested in: increased catalyst activity, increased catalyst space-time yield and CO conversion rate; enhanced thermal stability and heat resistance Good, long service life of the catalyst; good selectivity, high methanol content in crude methanol, less organic by-products; wide application range, easy reduction and operation, high strength, reduced catalyst powdering, low pressure drop, and is beneficial to improve the methanol plant The output.
