Why do we burn coal and trees to make solar panels
Restricting the air supply to a large mass of burning coal allows about 40% of the coal to "burn off" leaving behind a solid residue (coke) with a higher carbon content per ton that the original coal. It takes about 1.6 t of coal to make a ton of coke. Metcoke looks like porous, silvery grey coal.

Creating Iron | HowStuffWorks
The more advanced way to smelt iron is in a blast furnace. A blast furnace is charged with iron ore, charcoal or coke (coke is charcoal made from coal) and limestone (CaCO 3 ). Huge quantities of air blast in at the bottom of the furnace, and the calcium in the limestone combines with the silicates to form slag.

Metallurgical Coke
Metallurgical coke is an important raw material for pig iron production in the blast furnace. During this process the coke undergoes severe mechanical, thermal and chemical stresses. One of these is the CO2 -gasification which may lead to a decisive mechanical weakening of the lump coke by increased carbon burn-off.
