The effects of catalyst pore structure on the catalyst activity observed in the catalytic hydrodesulfurization reactions of asphaltenes were studied. In the simplified model, effective diffusivity and surface area were calculated using important physical properties of catalyst and the experimental hydrodesulfurization activity was analyzed based on this calculation. The existence of a maximal point in catalyst activity observed in the reaction could be explained in terms of the trade-off between the effective diffusivity and surface area.
