Deactivation of cobalt based Fischer―Tropsch catalysts: A review
TL;DR: In this paper, the main causes of catalyst deactivation in cobalt-based Fischer-Tropsch synthesis are poisoning, reoxidation of cobalt active sites, formation of surface carbon species, carbidization, surface reconstruction, sintering of crystallites, metal support solid state reactions and attrition.

Fischer–Tropsch synthesis: A review of water effects on the performances of unsupported and supported Co catalysts
Ajay K. Dalai,Burtron H. Davis +1 more
TL;DR: In this article, the effects of water on the performances of various cobalt catalysts for Fischer-Tropsch synthesis (FTS) are discussed. But the authors focus on the effect of water in terms of the performance of cobalt-based catalysts.

Study of the effect of water on alumina supported cobalt Fischer–Tropsch catalysts
TL;DR: In this paper, the effect of water on Co/Al 2 O 3 and CoRe/Al O 3 catalysts has been studied by adding water to the synthesis gas feed and by model studies exposing the catalysts to H 2 O/H 2 feeds using several characterization techniques such as TPR, gravimetry, XPS, TPD and pulse adsorption.

Metal−Support Interactions in Co/Al2O3 Catalysts: A Comparative Study on Reactivity of Support
TL;DR: In this article, it was found that the reactivity of the alumina support changes the surface structure and chemical composition of catalysts significantly when the metal−support interaction is weak, and the cobalt content on the surface decreases upon the increase in support reactivity.
