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.

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.
