Chemicals from Coking Metallurgical Coal. Most of the chemicals derived from coal come from byproducts produced during the coking process. Coal is used to make coke to make steel. Coke gas (also called foul gas) contains coke tars, ammonia, and light oils. Tars are recovered and used to make tar derivatives. Ammonia is recovered as an aqueous ...
