Abstract

Preparation procedure of pores for the manufacture of electrodes, from areas obtained by distillation of coal tars, characterized in that it is used as a starting material, a pitch whose softening point, determined by Kraºmer's method and Sarnov, is comprised between 55 and 65º C, said starting pitch being continuously supplied to a cooking zone in which it is maintained at a temperature comprised between approximately 380 and 340º C and in which a distillation of the oils it contains takes place, after having passed through successively, and against the current, vapors of oils coming from the cooking zone, a first treatment zone in which the condensation of the average fractions of distillation of said oils and their mixing with said tar is effected. split, and an intermediate treatment area in which the condensation of the heavy fractions of the indic Each oil and its mixture with the pitch from the first treatment zone mentioned, after which the pitch for electrodes formed in the indicated cooking zone is continuously removed.
