Abstract Scope |
The reduction kinetics of Fe2O3(purity 99.9%) under the condition of carbon separation was investigated by thermogravimetric isotherm with atmosphere controlled reduction experiment.TG curves were recorded during the experiment, and conversion rate, reaction rate, reduction rate and other parameters were calculated through experimental data.The results showed that the carbon evolution process was accelerated in the FeO→Fe stage, and the weight of samples was obviously increased.Through lnln method,the reaction mechanism function is G(a)=[-ln(1-a)]1/2, and the reaction activation energy is 43.4kJ/mol. |
