抄録
High temperature slags could act as not only heat carrier and catalyst but also reactants in some chemical reactions to produce syngas due to the individual components in slags. A new method is put forward to utilize the thermal energy of converter slags to generate CO gas which could improve the energy utilization efficiency. Thermodynamics of the reactions among coal, FeO–CaO–SiO2 slag and gas was studied by thermodynamic calculation under steady temperature condition or no enthalpy change condition. The effects of FeO amount in initial slag, mass%CaO/mass%SiO2 ratio of slag, and slag temperature on the behavior of the production of H2 and CO gases were clarified.
