In the present work such factors, which influence the reaction rate in residue hydrodesulfurization, as space velocity, temperature, pressure, hydrogen gas rate and feed oils were studied. In addition, trial catalysts were compared with a commercial catalyst for hydrogen consumption and catalyst activity. From the experimental results the following conclusions were obtained. (1) The rate of desulfurization reaction was apparently second order with respect to the sulfur concentration. The apparent activation energy was about 25kcal/mol. (2) The rate of sulfur removal increased linearly with increasing reaction pressure in the range of 50∼140kg/cm2. (3) The effect of hydrogen gas rate on the rate was relatively small in the range of 500∼1, 000Nl/l. (4) Khafji atmospheric residue was more difficult to desulfurize than Kuwait residue. (5) The trial catalysts were superior to the commercial catalyst with respect to hydrodesulfurization activity and hydrogen consumption.
