ABSTRACT:
Green petroleum coke is partly devolatilized by transporting horizontally in static bed form through a furnace over a series of air box zones including a minority of zones adjacent the input end of the furnace and a majority remote from the input end and further devolatilized by soaking in a shaft furnace until at least most of the residual volatiles are driven off. From the shaft furnace the devolatilized coke is water quenched and steam produced in the quencher is mixed with downdrafted gases from said furnace to cool the same and prevent premature combustion.
