- Abstract
- The effects of molar ratio of C/O and the particle size of char on carbothermic reduction of titanomagnetite (TTM) were investigated from a kinetic viewpoint at 1100 degrees C employing thermogravimetric analysis (TGA) and quadruple mass spectrometry (QMS). An increase in molar ratio of C/O results in a higher rate of carbon gasification, leading to an increase in final fraction reduction of TTM since excessive amount of char in TTM and char composite shifted the equilibrium in carbothermic reduction of TTM from the wustite/Fe equilibrium to that by the carbon gasification. With decreasing the particle size of char, the carbothermic reduction of TTM was improved by the activation of carbon gasification.
