Cobalt-based catalyst supported on γ-Al2O3 was prepared by impregnation method and loaded on ceramic monolith-structured substrate by wash-coating slurry method. Physico-chemical properties of the catalysts were characterized by X-ray diffraction (XRD), Brunauer–Emmett–Teller (BET) specific surface area and H2 temperatured-programmed reduction (H2-TPR). Activity of the catalysts for Fischer-Tropsch synthesis was investigated in a tubular reactor in a temperature range of 200-275 oC at 20 bar and GHSV = 3000 h-1. Co/γ-Al2O3 catalyst loaded on ceramic monolith-structured substrate enhanced efficacy of Fischer-Tropsch synthesis by increasing and stabilizing CO conversion and C5+ selectivity, compared to Co/γ-Al2O3 powder catalyst.
