摘　　要：为进一步探究合成气制甲醇工艺中催化剂中毒的原因,以XNC-98型催化剂的硫中毒情况为案例进行分析,分别探究了硫化氢、二氧化硫、甲硫醇和乙硫醇对催化剂中毒失活的影响,并进一步通过数据汇总分析确定甲硫醇和乙硫醇是引起本次催化剂中毒失活的主要成分。预计本次分析可为后续的工艺优化等环节提供一定的参考借鉴。In order to further explore the causes of catalyst poisoning in the synthesis gas to methanol process,the sulfur poisoning situation of XNC-98 catalyst was analyzed as a case study.The effects of hydrogen sulfide,sulfur dioxide,methyl mercaptan,and ethyl mercaptan on catalyst poisoning deactivation were investigated,and further data analysis was conducted to determine that methyl mercaptan and ethyl mercaptan were the main components causing catalyst poisoning deactivation.It is expected that this analysis can provide certain reference and guidance for subsequent process optimization and other aspects.
