Abstract
- A novel strategy that combines steam reforming of bio-oil and recovering waste heat from blast furnace (BF) slag was proposed, and the thermodynamic characterizations of steam reforming of bio-oil model compounds recovering waste heat from BF slag for hydrogen production were investigated. When temperature ranged from 600 to 700 °C, hydrogen yield and its component reached maximum, about 100 mol kg−1 bio-oil model compounds and 70%, respectively. The higher mole ratio of steam to carbon in bio-oil (S/C), the higher hydrogen yield and its component were obtained, but according to the practical process, the most suitable S/C was 4. The ordinary pressure (1 bar) was considered as the optimum pressure for steam reforming of bio-oil model compounds recovering waste heat from BF slag. At lower temperatures (below 500 °C), BF slag could promote hydrogen yield, but it slightly decreased equilibrium yield of hydrogen at the optimal conditions. Besides, BF slag could promote hydrogen component at lower temperatures (below 600 °C), but it had little effect at the optimal conditions. Solid carbon should be reduced during steam reforming of bio-oil compounds recovering waste heat from BF slag. [ABSTRACT FROM AUTHOR]
