Investigations of the catalytic hydrodesulfurization of Venezuela bitumen and its water emulsion (Orimulsion) were carried out. This material contained a large amount of sulfur and organometallics, such as vanadium and nickel compounds. A variety of nickel and molybdenum catalysts were prepared. These, as well as two commercial catalysts, were tested with Orimulsion and vacuum-dried, pentane-insoluble and soluble bitumen. Catalytic hydrotreatment removed up to 75% of sulfur from the bitumen. Hydrodesulfurization was found to be affected by reaction temperature, reaction time, catalyst, and feed material. Moisture-free bitumen and a pentane-soluble bitumen fraction were desulfurized more effectively than Orimulsion. Zeolite-based catalysts gave higher desulfurization than synthetic clay catalysts.
