초록

Study on clean and efficient utilization technology for low rank coal with high moisture content is actively ongoing due to limited reserves of petroleum and of high grade coal and serious climate change caused by fossil fuel usage. In the present study, supercritical water gasification of low rank coal was performed. With increasing reaction temperature, content of combustible gases such as H2 and CH4 in the syngas increased while the CO2 content decreased. As the reaction pressure increased from 210 to 300 bar, the CO2 content in the syngas increased while the hydrocarbon gas content decreased. The H2 and CH4 content in the syngas increased slightly with pressure. With the addition of Pd, Pt, and Ru catalysts, it was possible to improve the production of H2.
Moreover, the increase of active metal content in the catalyst increased the H2 productivity. The Ru catalyst shows the best performance for increasing the H2 content in the syngas, while decreasing the CO2 content.
