What substance is obtained as a residue when wood is burned in a limited supply of air?

When wood is burnt in a limited supply of air, a black substance is obtained as a residue, which is known as charcoal.

Charcoal is a lightweight, porous black carbon residue, consisting of an amorphous form of carbon, which is obtained by strongly heating wood (or other animal and plant materials) in minimal or limited oxygen to remove all water and volatile constituents. This process is called charcoal burning.
