Abstract
A system and process are provided for integrated deasphalting and desulfurization of hydrocarbon feedstock in which the hydrocarbon feedstock, an oxidant, and an oxidation catalyst are mixed prior to passage into a primary settler of a solvent deasphalting unit. Oxidation products, including oxidized organosulfur compounds, are discharged with the asphalt phase.
