摘要

Previous empirical research demonstrated that by mixing gasification and metallurgical slags at a specific composition in a CO_2 enriched environment, enough exothermic heat would be generated to transform CO_2 to CO. The process capacity may be limited by the availability of the slags, however, it could be used to supplement existing energy or chemical production to reduce overall carbon emission. In this study, computational simulations were performed to explore optimal process conditions based on effects of individual slag constituents and thermal input for maximal gas conversion rate, heat production, and volume increase. In simulated conversions of CO_2 to CO and H_2O to H_2, comparisons were made by varying CaO, FeO, versus V_2O_3 slag constituents. The result indicated the optimal slag composition may be obtained by appropriate source selection and mixing of gasification and metallurgical slags in order to maximize carbon reduction and/or H_2 production.
