Carbonization (or carbonisation) is the term for the conversion of an organic substance into carbon or a carbon-containing residue through pyrolysis or destructive distillation. It is often used in organic chemistry with reference to the generation of coal gas and coal tar from raw coal.

Conversion of organic substance into carbon. Carbonisation is destructive distillation of bituminous coal, done in the absence of air in order to obtain coke and other fractions having a greater percentage of carbon than the original material.

When coal is strongly heated continuously for 42 to 48 hours in the absence of air in a closed vessel, the process is known as Carbonisation.

Option A is pulverised coal.

B is Briquatted coal.

C is Wood charcoal.

Carbonization of coal consists of heating of coal to the the temperature as high as 1100*C in the absence of oxygen in order to distill out tars & light oils.
