The Characterizations of Hydrogen from Steam Reforming of Bio-Oil Model Compound in Granulated Blast Furnace Slag
The purpose of this research investigating the characterizations of steam reforming of bio-oil model compound in granulated BF (blast furnace) slag was to recover waste heat and obtain hydrogen. The results indicated that hydrogen yield and hydrogen fraction first increased and then decreased with the increase of temperature. When S/C increased, hydrogen yield and hydrogen fraction increased. But they decreased with the increasing LHSV. Hydrogen yield and hydrogen fraction were 1.68 m3 per kg of bio-oil model compound and 65.39% at the optimum condition with the temperature, S/C and LHSV reaching 750 °C, 9, and 0.9 h−1, respectively. Granulated BF slag containing metallic oxides as CaO and Fe2O3 could promote hydrogen yield and hydrogen fraction, so it was regarded as an excellent heat carrier for the reaction of steam reforming of bio-oil model compound.
