摘要：

CO2 Ultimate Reduction System for Cool Earth 50 (COURSE50) successfully carried out operational trials with an experimental blast furnace in which the effect of the reaction -control by COG (Coke Oven Gas) injection, top gas recycling, and use of high reducibility sinter on the carbon rate were determined. The conditions of the operational trials were designed by applying the mathematical blast furnace model that was developed. The results obtained in the operational trials indicate that the proportion of carbon direct reduction can be decreased while maintaining that of CO reduction, by the reaction -control by COG injection, top gas recycling, and use of high reducibility sinter. A reduction in the carbon rate of approximately 10% was achieved as predicted by the mathematical blast furnace model.
