  • Why should we study coal tar pitch fractions?
  • It can provide valuable information about the carbonization behaviour of coal–tar pitch fractions and the thermo-chemical process evolution during coke making, their influence on the mesophase formation with developing isotropic and anisotropic coke textures and, obviously, their use as chemical products.
  • What happens when Quinoline is dissolved?
  • By dissolving in quinoline the continuous phase of soluble matter having medium reflectance (β-resins) is almost completely removed, leaving QI grains with a porosity proportionally to its volume, ( Fig. 5 C). Sometimes big grains of β-resins include weakly degassed particles with anisotropic texture ( Fig. 5 D).
  • How does Qi-content affect a coal tar pitch binder?
  • The effect of the QI-content rise in coal–tar pitch binder appears in more isotropic coke textures that influence the contraction rate during electrodes baking, causing their fissuration. At the same time the required binder for electrode green mix must be increased.
