针对F-T合成铁催化剂对温度敏感的特点

提出了使催化剂活性在高温条件下先“钝化”

用集总法处理F-T合成动力学数据的新的研究方法及数学模型。采用固定床反应器对共沉淀型Fe-Cu-K工业催化剂F-T合成本征动力学进行了研究

求得本征动力学方程

为工业催化剂的进一步放大以及反应器的设计提供了理论依据。

To avoid the effect of the thermal sensitivity of Fischer -Tropsch catalyst(Fe -Cu -K) on the correlation of intrinsic kinetic data

the kinetic experiments are carried out over a passivated catalyst. A kinetic expression is obtained by using lumping method. Then

the final kinetic expression for fresh catalyst is obtained by modifying the k0 preexponential factor

in comparison with the fresh catalyst experiments.
