ABSTRACT:
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.
