The effect of noble metal on the LDH Ni/MgAl catalysts in operation of LPG steam reforming |
| 초록 |
The effects of noble metal addition on the activity and stability of layered double hydroxide (LDH) Ni/MgAl catalysts were investigated in the operation of LPG steam reforming at a temperature range of 600 ~ 850oC, feed molar ratio of H2O/C = 1.0 ~ 3.0, space velocity of 20,000 h-1 and atmospheric pressure. LDH Ni/MgAl hydrotalcite catalysts were prepared by a co-precipitation method and calcined to form Mg(Al,Ni)O periclase. The powders of periclase were dipped in aqueous solution of an noble metal chloride, dried at 110oC and calcined at 850oC for 5h. To compare with the activity, Ni/MgO and Ni/Al2O3 catalysts were prepared by an incipient wetness method. The characteristics of the fresh and used catalysts were analyzed by N2 Physisorption, CO Chemisorption, XRD, SEM and TEM. The noble metal modified LDH Ni/MgAl catalyst showed higher molar ratio of H2/CO than the other catalysts under the tested conditions. |
