Preface to the Special Issue on “Innovation for Ironmaking Systems Combined with Low-Carbon, Material Recycle and Energy Saving Technologies”

摘要

Given the lack of previous research on SMART system- based processes, the group set their own research base for the development of SMART system. CO? reduction processes were examined using solid oxide electrolysis and polymer electrolyte electrolysis. CO, emission reduction and iron material recycling processes and technologies in the iron and steel making processes were demonstrated experimentally and thermodynamically including tramp-element removal, carburiz- ing melting behavior analysis and hydrogen phenomenon on ironmaking process. Effect of SMART system on low-carbon ironmaking system was evaluated system process analysis by using results of the group researches. The candidates for the alternative primary energy were renewable energy and the high-temperature gas cooled reactor, which is capable of pro- ducing temperatures up to 950°C. The group members verified the technicalities of the SMART system; this special issue aims to integrate the results and innovation of this research. The conclusions of the study demonstrated that SMART system is capable of drastically reducing the CO emissions and raw material consumption from the ironmaking process, when com- pared with other low-carbon process proposals. It is effective in diminishing the burden of carbon capture and storage for the mitigation of CO, emissions, and is one of the pathways for a sustainable ironmaking process.
