Studies have been undertaken of the desulfurization of petroleum cokes in relation to the utilization of the delayed and fluid cokes arising from the refining of Athabasca oil-sands bitumen. Impregnation of the coke with sodium carbonate or hydroxide, followed by calcination in hydrogen or an inert atmosphere and subsequent leaching removed more than 90% of the sulfur. The effects of (1) coke particle size, (2) gas flow rate, and (3) calcination time and temperature have been determined. Weight ratios of reagent to coke from 0.02 to 1.0 have been investigated.
