Coal Tar an overview ScienceDirect Topics

Coal tar is a complex hydrocarbon mixture produced by thermal destruction (pyrolysis) of coal, typically a dark viscous liquid or semisolid with a smoky or naphthenic odor. The composition of coal tar will be influenced by the process used for pyrolytic distillation as well as by the original composition of the coal; however all coal

A source mixing model to apportion PAHs from coal tar

2010-12-1  Coal tar’s strongly pyrogenic signature and extremely high PAH concentrations have important implications for source apportionment studies, since the fraction of coal tar required to effectively saturate the isomer ratio in a pavement mixture need only be as high as 1/1000 (0.1%) of that of other PAH source
