The Role of Calcium added to Ni-based Hydrotalcite Catalyst for LPG Steam Reforming |
| 초록 |
Steam reforming of LPG over Ni/MgCaAl catalysts were carried out in a temperature range of 700℃, at atmospheric pressure with space velocity of 20,000 h-1 and feed molar ratio of H2O/C = 1.0. The catalysts were prepared by a co-precipitation. The Ni/MgCaAl catalyst showed higher resistance for the sintering of active metal than Ni-based hydrotalcite catalyst prepared by conventional method. It was found that Ni/MgCaAl catalyst showed high inhibition to the formation of carbon compared to Ni-based catalysts and maintained the activity at 700℃ for 50 h. The results suggest that the Ni/MgCaAl catalyst can be applied for the steam reforming of LPG. |
