摘要
综述了费托合成钴基催化剂及其失活原因的研究进展,阐述了催化剂的活性组分、载体、催化助剂等对反应活性和产物选择性的影响,分析了钴基催化剂失活原因,认为中毒、钴晶粒烧结、碳效应、钴再氧化、钴—载体形成化合物、机械磨损都会不同程度造成催化剂失活。
This paper summarized the research progress on cobalt-based catalyst used for Fischer-Tropsch Synthesis andcause for its inactivation,reviewed the influence of catalyst＇s active components,carrier and cocatalysts on reaction activityand product selectivity,analyzed the cause for cobalt-base catalyst inactivation,and believed that the poisoning,cobaltcrystal particle sintering,carbon effect,cobalt reoxidation,cobalt- carrier forming compound and mechanical wear cancause different degrees of catalyst inactivation.
