文献热力学值实验证实了本生反应产生H2SO 4-和HI-丰富的阶段。通过在一个含有H2SO 4产物和逆流液体I2流的系统中将H2SO 4溶液富集到57%，改进了利用本生反应的硫-碘水裂解循环。系统被SO2饱和。研究了H2SO 4的分解。Pt/SiO2、Pt/ZrO 2、Pt/TiO 2和Pt/BaSO 4都是高温下H2SO 4气相分解为SO2的良好催化剂。Pt/Al_2O_3催化剂的失效是由于基底硫酸化。指出了压力对硫酸化温度的重要性。H2SO 4蒸汽分解催化剂研究的总结比较了催化剂的有效性。
Literature thermodynamic values were experimentally confirmed for the Bunsen reaction producing H2SO4- and HI-rich phases. The sulfur-iodine water-splitting cycle, which uses the Bunsen reaction, has been improved by enriching the H2SO4solution to 57% in a system involving the H2SO4product and counter-current liquid I2flow. The system was saturated with SO2. The decomposition of H2SO4was investigated. Pt/SiO2, Pt/ZrO2, Pt/TiO2and Pt/BaSO4were all good catalysts for H2SO4vapor decomposition to SO2at high temperatures. Pt/Al2O3was found to fail due to substrate sulfation. The importance of pressure to sulfation temperature is presented. A summary of catalyst studies for H2SO4vapor decomposition compares catalyst effectiveness.
