| Summary, etc. | The reduction of iron ore fines/charcoal or coal composite compacts was carried out isothermally at 900-1100oC and non-isothermally up to 1100{u00B0}C using different heating rates 5, 10, 15 and 20{u00B0}C/min in a flow of Ar gas. The reduction reaction of iron ore /C composite compacts was carried out using thermogravimetric (TG) and Quadruple Mass Spectrometer (QMS) techniques. TG technique was applied to measure the total mass loss resulted during the reduction process as a function of time. Alternatively, QMS was used for the quantitative analysis of CO and CO2 in the outlet gases from the reduction reactions at different time intervals. For iron ore fine compacts, the reduction reaction was performed isothermally at 800-1100oC and non-isothermally up to 1000{u00B0}C using different heating rates 5, 10, 15 and 20{u00B0}C/min with purified CO gas and the total mass loss resulted during the reduction process as a function of time was followed by TG technique. The different phases developed during reduction of compacts were identified by X-ray diffraction analysis and the average crystallite sizes were calculated from the obtained X-ray data. The structural changes accompanying the reduction process were examined with reflected light microscope (RLM) and with scanning electron microscope (SEM). The reduction kinetics and mechanism deduced from TG and QMS techniques were correlated and discussed |
