High‐temperature steelmaking slags can 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 steelmaking slag for coal reforming to generate CO and H 2 gases which could be reused as energy. Thermodynamics of the reaction among carbon, FeO–CaO–SiO 2 slag, and CO–CO 2 –H 2 O gas is studied by FactSage 6.3 under steady temperature condition. In addition, effects of slag composition, slag temperature, and added carbon amount upon the production of H 2 and CO gases are clarified.
