Hydrodesulfurization of petroleum coke was studied in hydrogen flow at atmospheric pressure over the temperature range 650 to 850 degree C. The lump coke was desulfurized to the greatest extent at 650 degree C, 60% of its sulfur having been removed within 20 h. With lump coke the higher the desulfurization temperature, the lower the desulfurization level achieved. Grinding the coke increased the desulfurization level, at both 650 degree C and 750 degree , to 90 and 70%, respectively, within 6 h. In contrast, the desulfurization level at 850 degree C was always the worst.
