Study on Catalytic Activity over Ni/Mg/Al2O3 Hydrotalcite Derived Catalysts for Hydrogen Production |
| 초록 |
Ni/Mg/Al2O3 catalysts derived from a hydrotalcite precursor were studied for steam reforming of LPG with temperature range of 600 ~ 850oC, feed molar ratio of H2O/C = 1.0 ~ 3.0, a space velocity of 10,000 ~ 30,000 h-1 and atmospheric pressure. Ni/Mg/Al2O3 catalyst was prepared by co-precipitation method and Ni/MgO and Ni/Al2O3 catalysts were produced by an incipient wetness method. The Ni/Mg/Al2O3 catalysts showed higher conversion and H2 selectivity under the tested conditions and the catalytic activity increased with increasing reaction temperature. The characteristics of the fresh and used catalysts was analyzed by N2 Physisorption, CO Chemisorption, XRD, SEM and TEM. |
