Ni-Ce/Al2O3 catalyst with 11 wt. % Ni and 3 wt. % Ce was prepared by co impregnation method and calcined at 500 - 1000 °C in the flow of air. The DRM was carried out with and without previous reduction in a fixed-bed tubular reactor, using 20 mg of catalysts and a gas mixture CH4:CO2:He (16:16:68,100 ml/min) at 750 °C.
