Zero QI impregnated pitch from coal tar (TP1, TP2, and TP3) can also be made using solvent extraction or sedimentation process, which may not be costeffective. Depending on the required specifications for binder impregnated grade pitches, process parameters during vacuum distillation, were optimized through this collaborative work.

These byproduct ovens produced coal tar as one of the major byproducts. An industry developed around distillation of coal tar to produce various products. One of the major products produced is coal tar pitch. Since that time, coal tar pitch has become the binder of choice for the aluminum, commercial carbon, and graphite industries.

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 ...
