Abstract
The Co-Mo-Al and Co-Mo-Ce-Al catalysts were prepared and tested for their activity in the methanation of synthesis gas in the presence of hydrogen sulfide. The results showed that the Co-Mo-Ce-Al series was superior to the Co-Mo-Al system in terms of CO conversion. The former system was used to examine the main factors controlling the methanation behavior. Among these are: H2S concentration in the reaction mixture, reaction temperature and pressure, concentrations of CO2, CH4, and H2O, H2/CO ratio, and gaseous hourly space velocity. The methanation activity increased with increasing temperature, pressure and H2/CO ratio. The reason why adding CO2 or H2O decreases the methanation activity is discussed.
