제목 Slurry-phase Fischer-Tropsch synthesis using Co/γ-Al2O3, Co/SiO2 and Co/TiO2: effect of support on catalyst aggregation
초록 The activity of Fischer-Tropsch Synthesis (FTS) was investigated in a slurry-phase reaction with cobalt-based catalysts such as Co/γ-Al2O3, Co/SiO2 and Co/TiO2. Although Co/SiO2 catalyst showed higher CO conversion than the other catalysts, intrinsic activity is much higher on Co/TiO2 having a large pore size and cobalt particle size. Catalyst deactivation with the formation of catalyst aggregation was observed on Co/γ-Al2O3 which is characterized to show low formation rate of oxygenates. The alcohols derived FTS reaction and large pore size of catalyst possibly inhibit catalyst aggregation. Although the intrinsic activity (turn-over frequency; TOF) of cobalt-based catalyst is generally affected by cobalt particle size with different reducibility, the intrinsic activity is simultaneously affected by the average pore size of catalyst in a slurry-phase FTS reaction.
