Hydrogen Production from Steam Reforming of Glycerol over Ni based Hydrotalcite Catalysts |
| 초록 |
Steam reforming (SR) of over Ni based catalysts prepared by solid phase crystallization (spc) method under different conditions were investigated. The SR of glycerol was carried out in a fixed bed reactor with a temperature range of 600~800℃, an atmospheric pressure, a space velocity (GHSV) of 5,000~15,000 h-1 and feed molar ratio of H2O/C=1.3~3.0. The catalysts before and after the Glycerol SR were characterized by N2 physisorption, CO chemisorption, TPR, XRD, SEM, and TEM techniques. It was found that the Ni based hydrotalcite catalysts showed higher catalytic activity and stability than Ni/γ-Al2O3 catalysts. There is no formation of NiC during the reaction. However, it was slowly deactivated due to the carbon formation. The results suggested that the spc-Ni/MgAl catalysts was expected to improve catalytic stability because of the inhibition of coke formation during the SR of glycerol. |
