铁基费托合成催化剂研究进展

综述了近十年来铁基催化剂在费托合成反应中的研究进展，探讨了铁基催化剂活性组分的确定及影响铁基催化剂活性组分的因素，对比了3种催化剂制备方法（熔融法、沉淀法、负载法）和5种催化剂载体（氧化物、分子筛、碳材料、双孔材料和核壳材料）对费托合成反应性能的影响，从反应活性、选择性和反应稳定性3个方面阐述了助催化剂在费托合成反应中的作用。分析认为：碳化铁是铁基费托合成催化剂的活性组分；在铁基催化剂的制备过程中，选择适宜的制备方法、载体、助催化剂，可以达到提高费托合成反应活性、目的产物选择性和反应稳定性的效果。提出合成特定结构碳化铁、进一步研究铁基催化剂反应机理仍是未来研究的重点。

Recent advances in the development of iron-based catalysts for Fischer-Tropsch synthesis

This paper reviews the research progress of iron-based catalyst in Fischer-Tropsch synthesis (FTS)in recent ten years,mainly about the verification of the active sites and their affecting factors. We discussed the effect of three different preparation methods and five different supports on the properties of the supported iron catalyst and the influence of promoters on the catalytic performance from three respectives of activity,selectivity and stability of the promoted iron-based catalyst. The analysis showed that iron carbide was the active phase of iron-based catalyst and the selection of suitable preparation method,support and promoter can enhance the catalytic FTS performance. Based on the analysis and summary of the previous studies,we proposed that looking for new method for the synthesis of iron carbide with specific structure and studying on FTS mechanism are the key research focus in the future.
