摘要
A series of CoxMn0.06/SiO2 catalysts were prepared by an impregnation method for catalytic hydrogenation of CO to Light Hydrocarbons(LHCs).The catalysts were characterized by XRD,SEM,N2 adsorption and NH3-TPD techniques.Catalyst activities were evaluated in a high-pressure micro reactor.The results show that the performance of the catalysts was significantly affected by the amount of Co loaded onto the substrate.The activity of the Co0.10Mn0.06/SiO2 catalyst was stable with time-on-stream.The CO conversion and LHCs selectivity were 95.3% and 98.1%,respectively,for this catalyst at 400 °C.
