The industrial application of C307 type methanol synthesis catalyst developed by Sinopec Nanjing Chemical Research Institute Co., Ltd. in 600 kt·a^-1 methanol production plant of Shenhua Ningxia Coal Industry Group Co., Ltd. methanol branch was introduced. The selection, loading, heating, reduction, initial operation, normal production and the effect were described in detail. The results show that C307 type methanol synthesis catalyst has the advantages of good activity, high methanol selectivity and low unit consumption and stable operation. The application effect of C307 type catalyst for methanol synthesis was compared with that of upper-furnace catalyst in the system from the aspects of inert gas content, pressure difference of synthesis tower and one-way conversion rate of CO. The problems of low activity and high pressure difference in the initial stage of synthesis tower were analyzed and solved. The experience was summarized and suggestions were put forward, so as to provide reference for the selection of catalysts for different units.
