چکیده :

Promoted and unpromoted of cobalt catalysts were prepared using the incipient wetness impregnation method. For better evaluation of catalysts, the physicochemical properties of catalysts were investigated using brunauer-emmett-teller (BET), H2-TPR and X-ray diffraction. The performance of catalysts was studied in a fixed-bed reactor at 220oC, 25 bar, gas hourly space velocity (GHSV) of 2 L/h/gcat., and H2 to CO ratio of 2. The results indicate that ZrO2 as promoter can enhance the CO conversion and catalyst activity and enhance the selectivities of higher-molecular- weight products. From the reactor test, values of 160.3 mmol CO conv./gCo/h activity, and 0.12 gC3 +/ (h.gcat.) productivity have been obtained for the best catalyst.
