Coke Oven Gas
It is produced during the making of coke. It is also resulting from oxidation-reduction reactions of coal or coke with air and sometimes steams. It depends upon the type of coal used and operation method of oven. The composition of coke oven gas is H2 (54% vol), CH4 (24%), CO (8%), CO2 (6%) and some traces of higher hydrocarbon and nitrogen. With the application of heat the heavier hydrocarbons are cracked and volatile portion of coal is driven off and results in high composition of H2and CH4. Its heat value per cubic meter is only about one half that of natural gas and density is 0.40 kg/m3.
