dc.description.abstract In this work, lanthanum oxide (La2O3) has been studied for the methane partial oxidation reaction. We report long term experimental studies on La2O3, prepared by the solution combustion method with 5 wt% of Ni being added using chemical reduction method. Thorough characterization is done using XRD, SEM and FTIR. The activity is measured in terms of methane conversion and hydrogen and carbon monoxide selectivity. Methane oxidation is also carried out by varying the residence time, which changes the product distribution. Furthermore, methane activity is studied in the absence of oxygen and effect of pretreatment is also disused in detail. It is observed that the addition of nickel on the La2O3 catalyst (5 % Ni/La2O3) increases the catalytic activity significantly. Long term tests at isothermal conditions on both La2O3 and 5 % Ni/La2O3 catalysts are carried out to study the deteriorating effect of carbon (coke) deposition. Hydrogen production with 5 % Ni/La2O3 is significantly enhanced compared to La2O3, and it is experimentally observed that both the catalysts show excellent coking resistance capabilities. en_US
