Detailed Description. Coal tar is a byproduct of the coking, liquefaction, or gasification of coal. Coaltar pitch is the residue that remains after the distillation of coal tar. Coal tar and coaltar pitch are used in coaltarbased sealcoat products, although use of coaltar pitch is more common than use of coal tar. Both coal tar and coal ...

Coal tar distillate (of which creosote is a product) is a dark brown liquid that is produced by thermal distillation of coal tar. Coal tar is a biproduct of producing coke for steel production from coal via a pyrolytic process in "coke ovens" where the coal is heated to over 1,000°C in an oxygenlimited condition (Ametek 2022).The tar is distilled into lower, medium, and highboiling ...
