Analysis of typical cases of methanol synthesis catalyst deactivation
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.
