hey friend,

Coke is a fuel with few impurities and a high carbon content, usually made from coal. It is the solid carbonaceous material derived from destructive distillation of low-ash, low-sulphur bituminous coal. Cokes made from coal are grey, hard, and porous.

Coal tar is a thick dark liquid which is a by-product of the production of coke and coal gas from coal. It has both medical and industrial uses.As a medication it is used to treat psoriasis and seborrheic dermatitis(dandruff).It is used by application to the affected area and may be used together with ultraviolet light therapy. Industrial uses include preservation of railway ties and improving the surface of roads.
