1. A method of upgrading a heteroatom-containing hydrocarbon feed by removing heteroatom contaminants, comprising:
- reacting at least one of sulfones, sulfoxides, and mixtures thereof in the heteroatom-containing feed with at least one caustic and at least one selectivity promoter to produce an upgraded hydrocarbon.

Abstract
A method of upgrading a heteroatom-containing hydrocarbon feed by removing heteroatom contaminants is disclosed. The method includes contacting the heteroatom-containing hydrocarbon feed with an oxidant to oxidize the heteroatoms, contacting the oxidized-heteroatom-containing hydrocarbon feed with caustic and a selectivity promoter, and removing the heteroatom contaminants from the heteroatom-containing hydrocarbon feed. The oxidant may be used in the presence of a catalyst.
