    Dry distillation. Dry distillation is the process through which coal is gradually heated in the absence of air. The coke is given its desired characteristics by adjusting the temperature and the duration of the process. The high quality of the product obtained in this way allows us to meet the needs of customers around the world.

  • Dry distillationWikipedia

    Dry distillation is the heating of solid materials to produce gaseous products (which may condense into liquids or solids). The method may involve pyrolysis or thermolysis or it may not (for instance a simple mixture of ice and glass could be separated without breaking any chemical bonds but organic matter contains a greater diversity of molecules some of which are likely to break).

  • Pyrrole Structure Preparation Properties Uses

    Pyrrole occurs in coal-tar and bone oil. The bone oil is obtained by the dry distillation or pyrolysis of animal by-products such as horns hooves and bones. Pyrrole may be isolated from bone oil by first washing it with dilute H 2 SO 4 to remove the basic substances and then with dilute alkali to remove the acidic substances.
