分析了温度、碳储能、反应体系总压和惰性气体分压等因素对碳气化反应热力学的影响规律,并根据碳气化反应和铁氧化物的碳热还原反应之间的热力学联系,提出利用碳气化反应热力学的影响因素调控铁氧化物的碳热还原热力学,从而降低碳热还原温度,实现节能降耗的新思路:一是可利用碳气化反应热力学的影响因素降低铁氧化物的碳热还原温度;二是使Fe2O3在低于570℃下经Fe2O3→Fe3O4→Fe还原顺序被碳热还原为Fe。
The influence of temperature, carbon storage, total pressure of reaction system and inert gas partial pressure on the thermodynamics of carbon gasification reaction was analyzed. According to the thermodynamic relationship between carbon gasification reaction and carbon thermal reduction of iron oxide, This paper proposes a new idea of utilizing the influencing factors of thermodynamics of carbon gasification to control the thermodynamics of carbon thermal reduction of iron oxide so as to reduce the carbon thermal reduction temperature and realize the energy saving and consumption reduction. First, the influence factors of thermodynamics of carbon gasification can be used to reduce iron oxidation The second is to Fe2O3 at less than 570 ℃ by Fe2O3 → Fe3O4 → Fe reduction order carbon reduction to Fe.
