制备了一系列熔融铁催化剂并测定和评价了它们对CO加氢合成低碳醇的催化活性和选择性,从而确定了熔融铁体系催化剂最佳的组份含量。同时还研究了稀土氧化物添加剂和反应条件对催化剂的活性和选择性的影响。最后讨论了钾和稀土元素的作用以及熔融铁催化剂的催化机理。
A series of molten iron catalysts were prepared and their catalytic activity and selectivity for CO hydrogenation of lower alcohols were determined and evaluated. The optimum composition of the catalyst for molten iron system was determined. The effects of rare earth oxide additives and reaction conditions on the activity and selectivity of the catalysts were also studied. Finally, the role of potassium and rare earth elements and the catalytic mechanism of molten iron catalyst are discussed.
