ABSTRACT:
A process is disclosed for the removal of sulfur from petroleum fractions such as FCC gasoline by employing a solvent selected from the group consisting of a polyalkylene glycol, polyalkylene glycol ether, and mixtures thereof and having a molecular weight less than 400. The process is useful for saving energy, saving hydrogen consumption, and retaining octane. By requiring only the mild hydrotreatment of an extracted or absorbed stream concentrated with the sulfur impurities, the sulfur impurities are removed without the loss of octane resulting from conversion of either high octane olefins or aromatic components. In addition, the extract stream is a significantly smaller stream than the original feedstream.
