| Abstract: | The Ni based catalysts supported on La, Ba modified alumina were prepared and their properties were studied by BET, XRD and H 2 TPR. The activity and selectivity of these catalysts to the reaction of partial oxidation of methane to synthesis gas were also investigated. The results showed that La modified alumina have larger surface area and the biggest pore volume and pore diameter .The catalyst supported on it displayed the best activity and selectivity for catalytic partial oxidation of methane to synthesis gas when reacted at high temperature. |
