Abstract
Inventia se refera la un procedeu pentru tratarea cocsului partial desulfurat prin calcinarea cocsului cu un continut de maximum 2% sulf si tinut de maximum 2% sulf si avînd rezistenta mecanica a granulelor mai mica de 70% raportata la masa initiala a cocsului calcinat temperatura de calcinare fiind cuprinsa între 1300 si 1600 degree C timp de minimum 30 min, carcterizat prin aceea ca în scopul obtinerii unui cocs cu rezistenta granulelor soficienta folosirii acestuia la fabricarea anozilor pentru electroliza aluminiului se supune cocsul partial desulfurat, unui tratament suplimentar de calcinare la temperatura cuprinsa între 1200 si 1600 degree C pe o durata corespunzatoare diferitelor tipuri de cocs dar nu mai mica de 30 min.
