Highly KOH Resistant Ni-MgO-Al2O3 Catalyst for Direct Internal Reforming (DIR) in MCFC |
| 초록 |
Nano-sized MgO-Al2O3 supported Ni catalysts have been designed for direct internal reforming (DIR) in MCFC. Ni-MgO-Al2O3 catalysts (Ni content ＞ 50wt%) have been prepared by the co-precipitation method to finely disperse Ni crystallites on the support. NiO crystallite size has been found to be 2 ~ 4 nm, indicating nano-dispersion of NiO. The prepared Ni-MgO-Al2O3 catalysts have been poisoned by an appropriate amount of KOH and applied for steam reforming reaction at the same temperature and S/C ratio of MCFC (T = 650oC, H2O/CH4 = 3.0). According to the reaction results, Ni-MgO-Al2O3 with 10% MgO exhibits the highest KOH resistance among the catalysts tested in this study. |
