摘要

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.
