Abstract
Diesel fuels are decolorized by hydrotreatment under mild conditions. The feedstock is normally severely hydrotreated to convert organosulfur or organonitrogen and the effluent passed to a smaller downstream hydrotreating zone at a lower temperature but sufficient to lighten the color of a finished product hydrocarbon.
