Effect of sulfur dioxide partial pressure on the reaction of iodine, sulfur dioxide and water, which is a unit reaction of thermochemical hydrogen production IS process, was studied experimentally at 323K under iodine saturated condition. Quasi-equilibrium state was observed in the presence of sulfur dioxide gas of constant pressure. The composition of the poly-hydriodic acid solution was discussed assuming an ideal desulfurization using the reverse reaction of the Bunsen reaction. The value of HI/(HI+H $_{2}$ O) of the desulfurized solution was high in great sulfur dioxide pressure and reached the maximum of 15.70.3 mol%.
