| Research Abstract |
The reduction of carbon dioxide emissions has been urgently required to cope with the global warming. Iron and steel industry occupies approximately 14%of the anthropogenic greenhouse gas emissions of Japan. Drastic change of the properties is expected on the natural resources of ironmaking process, i. e., iron ore and coal. Therefore, it is important to positively utilize such change. The objective of the present study is to search for a new principle of ironmaking process, which can significantly reduce carbon dioxide emission. A series of the reduction experiments was carried out using composite materials of iron ore and carbonaceous materials under 80 atm at the elevated temperature. The database of the reduction behavior was prepared. Further, the optimum structure of the composite and new process principle was proposed.
