Abstract:

Aqueous phase reforming of glycerol over Ni-based catalysts for hydrogen production was carried out at 225 °C, 23 bar and LHSV = 4 h−1. The Ni-based catalyst was prepared by an incipient wetness impregnation method. The catalysts before and after the reaction were characterized by N2 physisorption, CO chemisorption, XRD, TPR, SEM and TEM techniques. It was found that Ni(20 wt%)–Co(3 wt%)/γ-Al2O3 catalyst showed higher glycerol conversion and hydrogen selectivity than Ni(20 wt%)/γ-Al2O3 catalyst. There are no major changes in Ni particles after the reaction over Ni–Co/γ-Al2O3 catalyst. The results suggest that the Ni–Co/γ-Al2O3 catalyst can be applied to the hydrogen production system using APR of glycerol.
