Abstract
A caustic desulfonylation method and system comprising a reactor vessel with a solid carbonaceous selectivity promoter provided therein, a liquid feed input of the reactor vessel configured to receive a source of caustic, a hydrocarbon feed comprising oxidized sulfur containing compounds and a gas feed input of the reactor vessel configured to receive a source of hydrogen. The caustic desulfonylation method and system further includes an output of the reactor vessel releasing the caustic and an upgraded hydrocarbon product with sulfur content less than the sulfur content of the hydrocarbon feed received by the liquid feed of the reactor vessel.
