Valuable Products from Coal Tar

Аннотация

Research on the production and properties of coal pitch is conducted in the laboratory at PAO Koks. One topic of interest is the distillation of coal tar to produce a broad tar and pitch fraction, whose quality is analyzed. It is possible to regulate the characteristics of pitch: its ash content and content of components insoluble in toluene (the α fraction) and components insoluble in quinoline (the α₁ fraction).
