Coking - Wikipedia

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 (as does a sheet of paper versus a wooden log).
