Utilization of low rank coal for iron making in a blast furnace is very difficult due to the structure of coal. We tried to coke low rank coal using oil-sand bitumen (OSB) as a binder, and evaluated the obtained coke by several methods including Raman spectroscopy and a polarization microscope. We evaluated the strength/structure of coke prepared from blended coal with/without OSB as a binder. Experimental results revealed that the utilization of OSB as a binder could be an effective way to coke the blended coal to obtain better performance.
