PROCESS FOR THE CALCINATION AND THERMIC DESULFURIZATION

Low sulfur calcined coke is produced from high sulfur raw coke without substantially lowering its bulk density by heating the coke at a first temperature such that no more than about 70 wt.% of the volatile matter is removed therefrom and then heating the partially devolatilized coke at a higher tem...

Beschreibung
Zusammenfassung:	Low sulfur calcined coke is produced from high sulfur raw coke without substantially lowering its bulk density by heating the coke at a first temperature such that no more than about 70 wt.% of the volatile matter is removed therefrom and then heating the partially devolatilized coke at a higher temperature sufficient to effect calcination and desulfurization.
