Abstract
The reaction of a Chinese bituminous coal PDS with Fe2O3 was investigated by such experimental means as thermogravimetric (TGA) coupled with Fourier transform infrared spectroscopy (FTIR) and TGA-difference thermal analysis (DTA) with focus on the effect of the heating rate. It was found that the reaction of PDS with Fe2O3 displayed three-staged reaction characteristics, and a higher heating rate facilitated more gaseous products from PDS pyrolysis to react with Fe2O3 and was more beneficial to the reaction of PDS with Fe2O3; and simultaneously, a higher heating rate made the overall activation energy for the reaction of PDS with Fe2O3 decreased from 62.79 kJ/mol at 20k/min to 56.50 kJ/mol at 35k/min, and finally, the heat needed for the reaction of PDS with Fe2O3 was less than that of PDS pyrolysis due to the exothermic reaction of Fe2O3 with H2 from PDS pyrolysis, and a higher heating rate made less heat needed for the reaction of PDS with Fe2O3.
