Gasification and metallurgical industries typically use coal and petroleum coke as carbon sources in the production of power, chemicals, and metals - processing which releases large quantities of CO2 and slag as waste by-products. Slag generated by these processes is comprised of non-volatile components from the feedstock, additives, and/or process ore impurities. Previous research demonstrated that by mixing gasification and metallurgical slags at a specific ratio in a CO2 enriched environment, enough exothermic heat was generated to transform CO2 to CO which could be used for energy or chemical production to reduce overall carbon emission. In this study, computational simulations were explored to optimize process conditions based on effects of individual slag constituents, adiabatic flame temperatures, and thermal input. In simulated conversions of CO2 to CO and H2O to H2; comparisons were made for slag FeO vs. V2O3 and for the present approach vs. traditional heat recovery.
