熱化学水素製造法ISプロセスの要素反応であるブンゼン反応について、ヨウ素飽和条件において二酸化硫黄分圧及び反応温度が生成するポリヨウ化水素酸相の組成に与える影響を調べた。理想的脱硫を仮定したポリヨウ化水素酸相のヨウ化水素酸濃度(HI/(HI/HO))は、二酸化硫黄分圧及び反応温度に応じて単調増加の傾向を示した。試験結果をもとに二酸化硫黄分圧及び反応温度の関数としてヨウ化水素酸濃度の実験式を得た。

Effect of sulfur dioxide partial pressure and reaction temperature on the composition of the poly-hydriodic acid solution produced in the Bunsen reaction, which is a unit reaction in the IS process for thermochemical hydrogen production, was studied experimentally under iodine saturation. The ratio of (HI/(HI/HO)) of the poly-hydriodic acid solution assuming an ideal desulfurization was increased with sulfur dioxide partial pressure and reaction temperature. The experimental equation on the ratio of (HI/(HI/HO)) was obtained as a function of sulfur dioxide partial pressure and reaction temperature.
