Abstract
The activity test of commercial catalysts of steam-hydrocarbon reforming was carried out under the wide range of working conditions（T=650∼850oC; S.V.=600∼1,200 hr-1; steam to carbon ratio=1.17）.
An activity test method has been developed through the parallel-triple-column gas chromatographic technique.
The following results were obtained:
（1） Hydrocarbons are scarcely found in the outlet gas except methane, and the gas composition could be approximately predicted by assuming the chemical equilibrium at the reaction gas temperature, among H2, CO, CO2, CH4, and H2O.
（2） It is difficult to compare the activity of catalysts by any direct comparisons of kinetic data at the high conversion level of reactants, while a conventional method proposed by Inoue et al. is eligible.
（3） It was concluded that the activity of commercial catalysts A, B, and C are approximately same.
（4） Steam to carbon ratio to prevent the carbon deposit was examined experimentally and theoretically.
