| 제목 | Sulfur Trioxide Decomposition using the Fe Catalysts in IS Cycle for the Thermochemical Hydrogen Production |
| 초록 | Iodine-Sulfur (IS) thermochemical process has been focused as a hydrogen production process. IS process is the continuous and closed cycle system consisting of three chemical step reactions; ⅰ) Bunsen reaction (I2 + SO2 + 2H2O = 2HI + H2SO4; 293-373 K), ⅱ) HI decomposition (2HI = H2 + I2; 473-973 K), ⅲ) H2SO4 decomposition (H2SO4 = H2O + SO3 → H2SO4 = H2O + SO2 + 0.5O2; 1073-1173K). Among the step reactions, SO3 decomposition is a catalytic reaction to convert SO3 into SO2 and O2 using the heat from VHTR (very high temperature gas-cooled reactor) in IS (Iodine-Sulfur) cycle. In this work, we prepared Fe supported on Al2O3 catalyst in this reaction. The molar ratio of Fe catalysts to Al2O3 was 0.25, 0.5, 0.75, 1.0. Catalytic reaction was performed in the temperature range of 750-950℃ changing the partial pressure and GHSV of the SO3 in a fixed bed reactor. |
