제목 | Catalytic Decomposition of SO3 using the Alumina and Titania Supported Catalysts in IS Cycle for the Thermochemical Hydrogen Production |
초록 | Hydrogen is an attractive energy carrier, which could replace the fossil fuels. One of the promising methods for hydrogen production is thermochemical water splitting using VHTR (very high temperature gas-cooled reactor) Recently, Iodine-Sulfur (IS) thermochemical process has been focused as a hydrogen production process with a great potential for industrialization. IS process is the continuous and closed cycle system consisting of three chemical step reactions; ⅰ) Bunsen reaction, ⅱ) HI decomposition, ⅲ) H2SO4 decomposition. SO3 decomposition is a step reaction to convert SO3 into SO2 and O2 using the heat from VHTR in IS cycle. In this work, we prepared Al2O3 (Fe/Al2O3, Ni/Al2O3 and Co/Al2O3) and TiO2 (Fe/TiO2, Ni/TiO2, and Co/TiO2) supported catalysts by an incipient wetness impregnation and a sol-gel method to develop a high performance catalyst in this reaction. Catalytic reaction was performed in the temperature range of 750-900℃ in a fixed bed reactor. |
