A study of steam reforming of hydrocarbon fuels on Pd/ceria

Differential steam-reforming rates were measured for methane, ethane, n-butane, n-hexane, 2,4-dimethylhexane, n-octane, cyclohexane, benzene, and toluene over 1 wt.% Pd/ceria between 620 and 770 K and were compared to rates observed on 1 wt.% Pd/alumina and 1 wt.% Pt/ceria. The H2O:C ratios at which stable rates were observed on Pd/ceria depended on the hydrocarbon, varying from less than 1:1 for methane to 3:1 for 2,4-dimethylhexane. In the...
