Thermodynamics Studies of Metal Oxides Conversion for CO2 Sequestration In Steel Industry

Due to the concerns of “global warming”, CO2 sequestration from steel industry are becoming more and more important for the environments FeCO3, one of component for steel, was selected to investigate in order to design suitable processing to sequestrate the CO2 at the steel plant. It was found that the raw material particle size, surface area as well as chemical components were important factors, which will effect on the CO2 absorption efficiency, cycle times, particle activities, and so on. Various analytical equipments such as SEM, XRD, FTIR, TGA, were used to analysis the processing and materials during the processing. Based on the above study,we designed an efficient chemical loop, which is not only sequestrate CO2 but also select suitable iron oar for the steel industryB
