Technology Type

Coking is the heating of Coal in the absence of Oxygen to a temperature above 600°C to drive off the volatile components of the raw Coal, leaving a hard, strong, porous material of high Carbon content called Coke. Coke consists almost entirely of Hydrocarbons. The porosity gives it a high surface area, which makes it burn faster. When a kilogram of Coke is burned it releases more heat than a kilogram of the original Coal.
