Abstract
A method and apparatus for recovering components from a hydrocarbon feedstock is provided. The method includes the steps of (a) supplying a hydrocarbon feedstock to an oxidation reactor, wherein the hydrocarbon feedstock is oxidized in the presence of a catalyst under conditions sufficient to selectively oxidize sulfur compounds and nitrogen compounds present in the hydrocarbon feedstock; (b) separating the hydrocarbons, the oxidized sulfur compounds, and the oxidized nitrogen compounds by solvent extraction; (c) collecting a residue stream that includes the oxidized sulfur compounds and the oxidized nitrogen compounds; and (d) supplying the residue stream to a fluid catalytic cracking unit.
