Coal Tar A Byproduct In Cokemaking And An Essential Raw

Jan 01, 2019 When distilled, the rich organic makeup of coal tar produces a series of industrial oils and a solid product called coal tar pitch (CTP), which accounts for about 50 wt% of the initial tar. CTP has a high carbon yield and on the basis of its physicochemical characteristics sports unique binding and impregnating properties, which cannot be fully supplied by petroleum-derived pitch.
