摘要

甲醇是连接现代煤化工和传统煤化工的平台产品。工业上通常采用合成气在催化剂作用下反应制备甲醇。甲醇合成催化剂的使用寿命通常在3~4年，保障甲醇合成催化剂的正常使用寿命对甲醇企业具有重要意义。对工业中甲醇合成催化剂硫中毒和铁中毒的典型案例进行了剖析，结合文献资料对中毒机理进行了阐述，指出铁中毒和硫中毒等是导致甲醇合成催化剂失活的主要原因，同时提出了相应的应对措施，可为保障甲醇合成催化剂的正常使用寿命提供指导。

Abstract

Methanol is a key product connecting modern coal chemical industry and traditional coal chemical industry. Industrially

methanol is typically produced by the reaction of syngas under the action of the catalyst. The service life of methanol synthesis catalysts is usually 3 to 4 years

and ensuring the normal service life of methanol synthesis catalysts is of great significance to methanol enterprises. Typical cases of sulfur poisoning and iron poisoning in industrial methanol synthesis catalysts were analyzed

and the poisoning mechanisms were explained based on literature data. It is pointed out that iron poisoning and sulfur poisoning are the main causes of methanol synthesis catalyst deactivation. Corresponding countermeasures were provided

which can offer guidance for ensuring the normal service life of methanol synthesis catalysts.
