Coal tar is a byproduct of the coking, liquefaction, or gasification of coal. Coal-tar pitch is the residue that remains after the distillation of coal tar. Coal tar and coal-tar pitch are used in coal-tar-based sealcoat products, although use of coal-tar pitch is more common than use of coal tar. Both coal tar and coal-tar pitch are known human carcinogens. Learn more about coal-tar

Coal-Tar Pitch - an overview ScienceDirect Topics
The process in which the carbonaceous binder, usually coal tar pitch or petroleum pitch, as part of a shaped carbon mix is converted to carbon yielding a rigid carbon body by the slow application of heat. The process can take as little as 14 days in coarse-grained, electrothermic grades (low binder level) and as long as 36 days in ultra-fine-grained, specialty grades (high binder level).

For a coal tar pitch sample, the heating value found was of 37.5 MJ.kg-1 (8,970 kcal.kg-1) and the specific gravity was of 1.32. Data from HPLC confirmed that biopitch molecular compounds are mostly polar (80-86%) and FT-ir of the same sample showed decreases in aliphatic hydrogen content when the SP increased. TGA/DTG analysis showed greater ...

4. CHEMICAL AND PHYSICAL INFORMATION
Coal tar pitch is the tar distillation residue produced during coking operations (NIOSH 1977). The grade of pitch thus produced is dependent on distillation conditions, including time and temperature. The fraction consists primarily of condensed ring aromatics, including 2–6 ring systems, with minor amounts of phenolic compounds and aromatic nitrogen bases. The
