How is coke obtained from coal?

Coke is obtained by destructive distillation of charcoal or coal in the furnace Destructive distillation is the chemical process involving the decomposition of coal or charcoal by heating to a high temperature in the absence of air or in the presence of limited amounts of oxygen.

How is coal tar formed 8?

It is a tough and porous black solid substance. It is prepared by heating coal in the absence of air. 1)When coal is heated in the absence of air,then coal gas and coal tar are eliminated,and coke is left behind as a black residue.
