硫对F—T合成反应的影响

本文综述了硫对Co、Ni、Fe、Mo催化剂F—T合成反应性能的影响。不同硫中毒方式对催化剂性能影响结果有所不同。催化剂中少量硫的引入对催化剂活性影响较小,而对某些催化剂其活性甚至增加。但当催化剂中硫含量超过某一值时,催化剂的活性明显降低。不同催化剂的抗硫能力与其组成、还原方式及反应条件等多种因素有关。

EFFENT OF SULFER ON THE FISCHER-TROPSCH SYNTHESIS

The effects of sulfer on performance of Co. Ni, Fe, and Mo catalysts for Fischer-Tropsh Synthesis were reviwed in this paper. The poisoning methods of sulfer affect greatly the catalytic performance of F-T catalyst. The resistance of sulfer of catalyst depends on its composition, methods of reduction, and reaction conditions. The catalytic activities of some catalysts are increased by adding a small amount of sulfer, but lots of amount of sulfer decrease the activity of F-T Synthesis catalyst.
