摘要：

To meet the global demand for energy, biochar can be a substitute and a green source of energy for fossil fuels and their derivatives. Biochar has its own supremacy to meet the requirements of the energy sector and replace coking coal for metallurgical purposes, and the mitigation of CO2 emissions from the Iron and Steel industry. This study includes the characterisation and comparative study of the reduction of iron ore pellets and iron ore fines using saw dust char (SDC) as one of the biomass wastes. The results show that the reduction of iron ore fines with comparable ratios with SDC gives the maximum degree of reduction than that of iron ore pellets. Thus, SDC can play an important role in the premium quality of coking coal reserves.
