제목 Production of high calorific synthetic natural gas using cobalt supported-catalysts
초록 Synthetic natural gas (SNG) from coal gasification is an environmentally friendly energy source. However, its heating value is lower than the standard heating value for power generation (especially in South Korea and Japan). This problem could be solved by adding C2-C4 hydrocarbons through Fischer-Tropsch reaction. In this study, Catalytic performance and characterization were investigated to elucidate effect of metal support interaction between cobalt and support (Al2O3 and SiO2). The TPR profile of the Co/SiO2 showed the lower reduction temperature than that of the Co/Al2O3. The XRD peaks of Co/SiO2 showed Co metal peak from Co3O4 after reduction at 400 °C, while Co/Al2O3 did not indicate Co metal peak but CoO peak. The Co/SiO2 exhibited higher CO conversion compared to Co/Al2O3 under H2/CO = 3.1, 10 bar and 300 °C, because of better reducibility of cobalt in Co/SiO2. In addition, its heating value is similar to that of noble metal catalyst in previous literature. Therefore, Co/SiO2 could be the promising catalyst for the production of high calorific SNG.
