Difference Between Coal Tar and Bitumen

The key difference between coal tar and bitumen is that coal tar is a synthetic substance, whereas bitumen is a naturally occurring substance.. Both coal tar and bitumen can be observed as dark, thick, highly viscous liquids. These are mainly composed of carbon.Bitumen, also called asphalt, can be found either naturally or it occurs as a byproduct of refining processes.
