What is the process of conversion of coal to coke?

1. When coal is heated to a certain temperature while cutting out air supply, it turns into a residue of solid carbonaceous form known as coke. 2. The nature of the residue depends on the temperature at which the coal is heated. Generally it is hightemperature carbonization which helps convert coal to coke.
