(54)	Highly aromatic petroleum pitches, their preparation and use in the manufacture of electrodes

(57) A procedure for obtaining non-polluting petroleum pitches for their use in the manufacture of electrodes and other graphitic compositions. It comprises the subjecting of a petroleum fraction or residue to a heat treatment at temperatures lying between 350° and 470° C, preferably between 370° and 430° C, for a time less than 120 minutes, preferably less than 60 minutes and in an inert atmosphere at a pressure under 20 atmospheres, preferably under 10 atmospheres absolute.
