ABSTRACT:
An integrated method for refining a hydrocarbon distillate fraction such as kerosene which has sulfur-containing compounds by washing the fraction with an alkaline solution and then sweetening the resulting distillate by treating it with a phthalocyanine catalyst in the presence of a second alkaline solution and oxygen while simultaneously disposing of the spent caustic from the washing by incinerating same in the presence of a sulfur-containing fuel and oxygen to yield harmless sulfates.
