The desulfurization of the resids from a West Coast crude and a Kuwait crude is analyzed as a function of the pore structure of the cobalt moly catalyst and the percentage of asphaltenic sulfur in the crudes. The two crudes are characterized in detail. The refractoriness of asphaltenes or resistance to desulfurization is considered from the tendency of a fine pore catalyst partially to exclude asphaltenes and the complete steric hindrance of sulfur in asphaltenes. The effect of coke deposition on the pore size distribution and asphaltene exclusion as a function of temperature are determined. The exclusion of asphaltene is related to the distribution of Ni inside and outside the catalyst pore structure, but there appears to be no correlation with the V distribution. (JSR)
