The activity of 7.25% molybdenum oxide and 3.37% cobalt oxide, supported on Corning alumina monolith, for the sulfur and nitrogen removal from a light feedstock (Raw Anthracene Oil) and a heavier Synthoil process liquid was compared with the activity of the previously characterized Nalco Chemical Co. Nalcomo 474 catalyst. The experiments were conducted in the previously used trickle-bed reactor at 700/sup 0/F and 1500 psig. On either weight or volume basis, the nalcomo catalyst was more active than the monolith for sulfur and nitrogen removal from the light oil, and less active for sulfur and nitrogen removal from the Synthoil. The higher activity of the monolith catalyst (87.6 A. avg pore radius, 0.114 mm intraparticle diffusion length) than of the nalcomo catalyst (31 A. avg pore radius, 1 mm intraparticle diffusion length) was attributed to diffusion limitations in the latter. The effectiveness factors, derived from the observed hydrodesulfurization rates, were 0.94 for the monolith and 0.216 for Nalcomo 474.
