Abstract
This study aims to investigate the physical and chemical transformation of agricultural wastes during gas phase reactions with applications in electric arc furnaces steelmaking. Palm shell and coconut shell blended in different proportions with cokes were combusted in a drop tube furnace and were pyrolyzed in a thermogravimetric analyser at 1473 K. Coke/agricultural blends indicated higher combustion efficiencies. Scanning electron microscopy showed that the pore structure in the char particle from agricultural blends became lost of cell lumen and higher surface area, supporting the higher combustion efficiency in comparison with cokes alone.
