Kinetic study on the hydrotreating of heavy oil. 2. Effect of catalyst pore size

· Ind. Eng. Chem. Res.; (United States)
The hydrodemetalation reactions of residual oil were carried out by use of a trickle bed reactor to investigate the relation between catalyst pore diameter and activity. The catalysts used were 3% molybdenum on alumina and silica-alumina. The results showed that the optimum pore diameter was located around 100 -- 150 A at 400/sup 0/C. The optimum pore diameter increases with the elevation of reaction temperature, and the curve showing the change of metals removal with pore diameter becomes broader at higher reaction temperature. The selectivity between two reactions, such as vanadium and nickel removal, passes through a maximum with varying the pore diameter.
