Abstract

In present investigation, RUTHENIUM was deposited on COBALT supported alumina catalyst by CHEMICAL VAPOR DEPOSITION (CVD) of Ru3 (CO) 12 for FISCHER-TROPSCH SYNTHESIS (FTS). The 15.0 wt% Co/g-Al2O3 catalyst was prepared by wet impregnation of COBALT nitrate aqueous solution, and then dried and calcined at 400oC for 4 h. To optimize the CVD operating conditions in which Ru3 (CO) 12 starts to decompose on surface of the catalyst, the decomposition products of the CVD processwere passed through a gas cell of FT-IR. In a specific temperature range, RUTHENIUM deposited selectively on the surface of COBALT active phase. The CVD of RUTHENIUM onto Co/g-Al2O3 catalyst increased the catalyst reducibility which in turnled to a higher CO hydrogenation activity in FTS process. Furthermore, the promoted COBALT catalyst showed a better selectivity towards heavy hydrocarbons than the reference unpromoted catalyst. The effects of temperature (210oC-240oC) and H2/CO ratio (1-3) for all catalysts were examined. For the all operating conditions, the promoted catalyst performed much better than the unpromoted catalyst.
