Abstract – In this paper, we describe three intrinsic deactivation modes observed in experimental cobalt Fischer-Tropsch synthesis catalysts: cobalt oxidation reversible by mild hydrogen treatment, cobalt agglomeration, and cobalt-support mixed oxide formation. All three mechanisms involve redox transformation of the catalytically active cobalt metal.
Biography – Gabor Kiss received his M.Sc. in chemical engineering from the University of Veszprem (now Pannon University), Hungary, in 1981. He worked in the Hungarian oil industry for eight years before enrolling the graduate school at the University of Miami. After receiving his Ph.D. in chemistry in 1993, he accepted a position at Exxon’s (now ExxonMobil) Corporate Research Laboratories in Clinton, NJ, where he is currently a Sr. Scientific Associate. His research interests include the kinetics, thermodynamics, and mechanism of both homogeneous and heterogeneous catalytic processes. He has published 26 peer-reviewed papers and has 38 patents.
