The pyrolysis of coal, at high temperature and without air, produces coke and gas (coke oven gas). The cooling of this gas allows the condensation of a black product that is coal tar, which is recovered after decantation. Tar is a viscous liquid at ambient temperature; its viscosity becomes low enough from 60°C.
> Tar Distillation Industry: To obtain pitch (for anodes in the aluminium industry and electrodes for the steel production in electric arc furnaces), carbon black oils, creosote oils (for the wood treatment), washing oils (for benzole removal), and naphthalene.
