Abstract The application of presulfide resistant sulfur shift catalyst developed by Shandong Qilu Keli Chemical Institute, used in the purification unit of Zhongtian Hechuang Chemical Company was introduced. The results show that the loaded presulfide sulfur resistant shift catalyst can import process gas immediately after heating, and start process is convenient, and clean and environmental, and has high transformation activity and good stability in the normal run-time, save the time and cost of start-up greatly, and is suitable for purifying and treating crude synthesis gas.
