Patent ·
OSTI ID:7215891

A process for decolorizing distillates is described which comprises passing a stream of hydrocarbon distillate through a dilute sulfuric acid solution in the presence of contact material and an alkaline solution in succession then through a plurality of chambers containing contact material and concentrated sulfuric acid and arranged in series relation. The passage of distillate is continued until the concentrated sulfuric acid is substantially exhausted in the chambers. The exhausted concentrated sulfuric acid and reaction products are removed from successive chambers and treated with water to obtain a dilute acid solution.
