Abstract
The invention relates to the production of brea from distillates arising from high temperature coal tar having a distillation range of more than 260 °C, by means of sequential and combined application of three stages in mild pressure and temperature conditions (<400° C, <10 bar g), oxidative thermal treatment used as a reagent for air or oxygen, mixtures thereof, or air which is low in oxygen, thermal treatment in an inert atmosphere and fractionated distillation. It is possible to obtain brea exhibiting environmental advantages and advantages in term of occupational health, which can be used as coal precursors.
