  • Process for improving the cetane number of a gas oil cut
    Publication number: 20050029161
    Abstract: A process for transforming a gas oil cut from a conversion process or from an aromatic crude is described, the aim of the process being to improve the cetane number of said cut. The process comprises at least one hydrogenation step in which said gas oil cut is passed, in the presence of hydrogen, over a catalyst comprising an amorphous mineral support, at least one compound of a group VIB metal, at least one compound of a non noble group VIII metal and at least phosphorous or a compound of phosphorous, the process then comprising a hydrocracking step in which the hydrogenated feed is passed, in the presence of hydrogen, over a catalyst comprising an acidic support, at least one compound of a group VIB metal and at least one compound of a non noble group VIII metal.
    Type: Application

  • Plant for purifying spent oil
    Patent number: 5843384
    Abstract: The invention concerns a plant for purifying spent oil, including apparatus for dehydration, preferably by atmospheric distillation, directly followed by vacuum distillation producing a residue and at least one distilled oil fraction. The vacuum residue directly undergoes solvent extraction and the clarified oil obtained and the distilled oil fraction(s) undergo finishing hydrotreatment.
