Thermodynamic Study on the Ability of Biomass to Directly Reduce Iron Oxides
摘要
Abstract
The application of biomass in ironmaking can help reduce CO2 emissions.The minimum Gibbs free energy thermodynamic equilibrium model is constructed for the direct reaction system between biomass and Fe2O3,8 types of biomass are used as reducing agents,and the influence of Fe2O3 mass is analyzed on system indicators.The results indicate that the reduction process can be divided into five stages based on the type of product.The metallization rate in both the first and second stages is 100%,and the metallization rate gradually decreases to 0%in the third stage.In the third stage,the ratio of the mass of equilibrium H2 to the mass of equilibrium H2+H2O is 62.81%,which is not affected by changes in biomass type.In the first stage,the gas production shows an increasing trend,while in other stages it remains unchanged.关键词
