Square channel cordierite monolithic catalysts for Fischer-Tropsch synthesis (FTS) have been prepared and evaluated. Two different methods to apply the washcoat layer were used; washcoating the available Co-Ru/γ- Al2O3 catalyst and the second method involving washcoating of γ-Al2O3 followed by the impregnation of the active phase and promoter. The catalysts have been evaluated in a laboratory reactor and have been characterized using XRF, XRD, TPR, SEM, BET surface area and adhesion measurements. The effect of changing the promoter was studied and Re showed a better performance than Ru. The activity and selectivity of the monolithic catalysts were compared with the corresponding powder catalysts. The monolithic catalysts prepared with the second washcoating method were further examined with reaction conditions have been tested in a temperature range of 210–250 ºC and in different feed flow rates (20-50 ml/min) with synthesis gas compositions consisting of H2/CO ratio of 1 to 3. The effect of these processing conditions on the activity, selectivity and chain growth probability of monolithic catalysts for FTS were investigated.
