Abstract

Agricultural waste can be an interesting possibility to be applied as reducing agent instead of coal-based used in steelmaking which is considered to be one of the largest energy intensive sector. As a result of enormous amount of wastes generated by agricultural sectors, numerous research on application of waste as energy source have been conducted. Utilization of these wastes as valuable materials could provides solution to environmental problems. This present study investigated the reduction of iron oxide with agricultural waste from palm shells in a horizontal tube furnace. Composite pellets of iron oxide (96.0 % Fe2O3) with palm char in three different proportions were rapidly heated up to 1550 °C under argon gas flow. The reduced sample after reaction time, 30 minutes was examined using a Scanning Electron Microscope (SEM) equipped with Energy Dispersive Spectroscopy (EDS) and measured for degree of reduction. The results indicated that iron oxide which composed primarily Fe2O3 can be effectively reduced by palm shells as reductant where a significant improvement in the degree of reduction. The initial hematite powder could successfully reduced to metallic iron after a complete reduction process. This finding indicates that carbon from palm shells could be used as reductant in steelmaking processes.
