| 摘 要： | 利用热力学基础数据对F-T合成催化剂硫化氢中毒的热力学进行了计算。在热力学上，Ru、Fe、Co的毒化在F-T合成反应可以发生的条件下均是自发过程。F-T合成反应体系中10-8级浓度的H2S即可使Ru基催化剂中的金属Ru生成RuS2而中毒。Fe和Co关 键 词： | F-T合成 催化剂 热力学 中毒 抗硫性 |

| Abstract: | The thermodynamics of poisoning on F-T synthesis catalyst with hydrogen sulfide was determined according to some thermodynamic data and related software.Poisoning of Ru, Fe and Co may occur spontaneously under the condition of F-T synthesis reaction because of the low negative value of ΔG. Metal ruthenium in Ru-based F-T synthesis catalyst may be poisoned by H2S even to 10-8 level.There are many types of Fe and Co sulfides generated in the poisoning reactions.Their equilibrium constants are different for different reactions, and their concentrations of hydrogen sulfide required are also different.The concentration limitation of hydrogen sulfide is obtained.The results provide useful data and theoretical guidance to the development of sulfur tolerant F-T synthesis catalyst. |
