摘　　要：合成催化剂的活性直接影响着催化剂的寿命和产量。阐述了影响甲醇合成催化剂活性的4种因素,包括羰基金属等金属毒物、硫及硫化合物、氯及氯化合物、微量氨。并从实际运行情况中逐项数据分析,确定引起催化剂中毒失活的原因,进而采取相应的措施保护催化剂,延长催化剂的寿命,提高催化剂的产量。The activity of synthetic catalyst directly affects the service life and yield of catalyst. Four factors affecting the activity of methanol synthesis catalyst were described, including metal poisons such as carbonyl metals, sulfur and sulfur compounds, chlorine and chloride compounds and trace ammonia. The causes of catalyst poisoning and deactivation are determined by analyzing the data item by item from the actual operation, and then corresponding measures are taken to protect the catalyst, prolong the service life of the catalyst and improve the output of the catalyst.
