Metallurgical Coke. Metallurgical coke is the macroporous solid carbon material which is produced by carbonization of coking coals of specific rank or of suitable coal blends at the typical temperature range of 900–1100 °C in the absence of air or in the presence of only limited supply, i.e., during the destructive distillation of coal.

Bitumen is also frequently called tar or pitch—though, properly speaking, tar is a byproduct of the carbonization of coal and pitch is actually obtained from the distillation of coal tar. Bitumen is defined by the U.S. Geological Survey as an extra-heavy oil with an API gravity less than 10° and a viscosity greater than 10,000 centipoise.

The coal formation process involves the burial of peat, which is made of partly decayed plant materials, deep underground.
