摘要：A novel method combining steam reforming of tar for hydrogen production and recovery waste heat of BF (blast furnace) slag was proposed. The thermodynamic characterizations of steam reforming of tar model compound with BF slag were obtained via Gibbs minimization approach. The effects of temperature, S/C (the mole ratio of steam to carbon in the tar model compound) and BF slag on the process of steam reforming were illuminated. With BF slag, the hydrogen yield first increased then decreased with the increasing temperature and it reached the maximum value with the temperature of 590°C. The hydrogen yield increased with the increasing S/C and the optimal S/C was 7 for industry application. At the optimal condition, the hydrogen yield reached 25.98 moles per mole of tar model compound. BF slag could promote the hydrogen yield at the optimal condition, which was regarded as a promising heat carrier for the steam reforming process.
