Calcination of delayed and fluid oil sand cokes with alkaline reagents at high sodium/sulfur ratios followed by leaching gave almost complete desulfurization in terms of gaseous combustion products. Use of smaller proportions of alkaline reagents with hydrodesulfurization at 650 to 850°C also resulted in extensive removal of sulfur as hydrogen sulfide.
