Those effects of water/carbon ratios on partially oxidizing and steam reforming of gasoline, which used n-octane as reactant, have been investigated in this paper. The theory analysis showed that the reaction had optimum ratios of water/carbon and oxygen/oil at certain reaction temperature in the condition of adiabatic reaction. The experimental results showed that the conversion efficiency of n-octane and the selectivity of production hydrogen were increased with water/carbon ratio at certain reaction temperature and oxygen/oil ratio in the condition of non-adiabatic reaction. The reaction should be carried out at certain water/carbon ratios in order to produce hydrogen for fuel cell by gasoline without supplying energy to the reaction system. The optimum ratios of water/carbon were in the range of 1.5-2.5 in the experimental conditions.
