| Abstract: | The Co-based catalysts were prepared by fractional impregnation method and the MgO support was prepared by Co-precipitation method.The surface properties and catalytic performance of supported CoO catalysts for CO2-reforming of CH4 to syngas were investigated by using technigues such as XRD,H2-TPR,CO2-TPD and evaluation of catalytic activity,etc.The results showed that the sample supported on the Co-precipitated MgO gave a higher specific surface area(SBET(MgO)) and a better catalytic performance.The catalytic reaction was stable for 120 h on stream with a CH4/CO2 feed ratio of 1∶1 at 750 °C and GHSV=2500 h-1. |
