A reaction system and method for removing heteroatoms from oxidized-heteroatom-containing hydrocarbon streams and products derived therefrom are disclosed. An oxidized-heteroatom-containing hydrocarbon feed is reacted in a reaction system thereby forming non-ionic hydrocarbon products. The products derived therefrom are useful as transportation fuels, lubricants, refinery intermediates, or refinery feeds.

1. A reaction system for reducing a heteroatom content, reducing a total acid number, and increasing API gravity of an oxidized-heteroatom-containing hydrocarbon feed stream comprising: an oxidized-heteroatom-containing hydrocarbon feed stream;reactor vessel configured with a first feed inlet receiving the oxidized-heteroatom-containing hydrocarbon feed stream and a second feed inlet receiving a caustic and selectivity promoter stream;a reaction region of the reactor vessel, wherein the oxidized-heteroatom-containing hydrocarbon feed stream contacts the caustic and selectivity promoter stream;a first outlet attached to the reactor vessel configured to receive a heteroatom free hydrocarbon product; anda second outlet attached to the reactor vessel configured to receive a used caustic, selectivity promoter and a sulfate salt. 2. The reaction system of claim 1, wherein the selectivity promoter is selected from the group consisting of ethylene glycol, propylene glycol, glycerol and pinacol. 3. The reaction system of claim 1, wherein the selectivity promoter is a polyol. 4. The reaction system of claim 1, wherein the heteroatom free hydrocarbon product is an unsubstituted aromatic hydrocarbon. 5. The reaction system of claim 4, wherein the unsubstituted aromatic hydrocarbon is a biphenyl. 6. The reaction system of claim 1, wherein the caustic is a molten caustic. 7. The reaction system of claim 6, wherein the molten caustic is selected from Li2O, Na2O, K2O, Rb2O, Cs2O, Fr2O, BeO MgO, CaO, SrO, BaO, LiOH, NaOH, KOH, RbOH, CsOH, FrOH, Be(OH)2, Mg(OH)2, Ca(OH)2, Sr(OH)2, Ba(OH)2 and molten mixtures thereof. 8. The reaction system of claim 1, wherein the reactor vessel is a countercurrent reaction column.
