Metallurgical (iron & steelmaking) and gasification (power and chemicals) industries generate large amounts of carbon dioxide as byproduct from carbon raw materials; along with slag, another byproduct formed from non-volatile mineral components of the carbon feedstock, additives, and/or ore impurities. Thermodynamic simulations indicated that, if two slags are mixed, CaO (rich in most metallurgical slags) and V2O3 (rich in petcoke gasification slags) would form (CaO)3(V2O5) by stripping an oxygen atom from CO2 under certain conditions. The concept was explored using blends of synthetic metallurgical and gasification slags of a targeted chemistry, which were exposed to a CO2 rich gaseous environment at elevated temperatures. Result indicated about 97% CO2 was reduced to CO within five minutes at the reaction temperature. Potential utilization of CO and heat generated from the exothermic reaction will be discussed.
