摘　　要：费托合成(F-F合成)是实现煤间接液化技术的重要环节之一,其关键是开发高活性、选择性和稳定性的催化剂。目前应用的费托合成催化剂主要有铁基和钴基催化剂。铁基催化剂因价格低廉、催化活性和水煤气变换反应(WGS)活性高以及助剂效果明显,而在费托合成催化剂中占有重要的地位。本文对近几年铁基催化剂的特点和发展状况进行了评述,着重分析了催化剂制备过程、助剂和还原活化对其活性和选择性的影响。Fischer-Tropseh synthesis is one of the most important technologies for syngas to liquid. The activity and selectivity for catalysts are key factors in this process. At present, there are mainly two kinds of catalysts, Fe-based and Co-based ,for it. Fe-based catalysts have lower cost but higher WGS activity ,compared with Co-based catalysts.The characteristic and development of Fe-based catalysts are reviewed, and then the factors affecting the activity and selectivity of catalysts are analysed.
