项目摘要

It is important for environmental protection to use waste materials effectively. In this work, we conducted fundamental researches on the application of carbonaceous materials from waste as a reducing agent in an ironmaking process. Carbonaceous materials from waste (carbonized municipal waste and carbonized woody biomass) were mixed with a hematite reagent. The mixtures were heated up at the temperatures of 1000-1200℃ in N_2 gas by using a thermo gravimetric analysis (TG) or a vertical tube electric furnace. As a result, however a reaction of the mixture sample using a graphite stagnated, a reaction of the mixture sample using the carbonized municipal waste and the carbonized woody biomass progressed without the reaction stagnating. This is because a reactivity of the carbonized municipal waste and the carbonized woody biomass is better than that of the graphite.

有效利用废旧物资对环境保护具有重要意义。在本工作中，我们对废旧碳质材料作为还原剂在炼铁过程中的应用进行了基础性研究。将来自废物(碳化的城市垃圾和碳化的木质生物质)的碳质材料与赤铁矿试剂混合。用热重分析(TG)或竖管电炉将混合物在N_2气氛中加热至1000-1200℃。然而，结果是，使用石墨的混合样品的反应停滞，使用碳化的城市垃圾和碳化的木质生物质的混合样品的反应进行，而没有反应停滞。这是因为碳化的城市垃圾和碳化的木质生物质的反应性比石墨更好。
