摘要
Fe基催化剂的广泛应用不仅在于Fe元素本身的结构,许多助催化剂能对其活性、选择性、稳定性及还原性能产生巨大影响也是主要的原因.本文讨论的Cu,K助剂促进的Fe催化剂,用于F-T合成是比较理想的.它不仅显示了良好的催化活性,Cu。
The reduction process of copper, potassium promoted iron-based catalysts for Fischer-Tropsch synthesis prepared by co-precipitation and impregnation method was studied by temperature-programmed reduction (TPR). The mechanism of reduction of Fe catalyst was suggested. The effects of promoter copper, potassium on the reduction process and mechanism were discussed. The kinetic parameters of the reduction process were also calculated.
