Definitions

  • the present invention relates to an improved method of catalytic treatment for lubricating oils obtained from the distillates of petroleum products, in order to improve the odor, color and stability of the commercial products.
  • This method comprises bringing the oily distillates, which have preferably been previously refined by solventextraction and from which the parafiin has preferably been previously removed, into contact, in the presence of hydrogen, with a particularly effective catalyst (which will be indicated hereinafter), and in operating under conditions such that there is practically no reduction of the sulfur compounds present in the treatedv oil, because it has been found that these, acting as natural inhibitors, have a favorable action as regards the stability of the finished products.
  • hydro-desulfurizing catalysts are oxides or sulfides of cobalt and molybdenum, free or combined, deposited on porous supports.
  • a catalyst obtained by making a paste of heavy magnesia with an ammoniacal solution of cobalt molybdate has the following composition after drying at 400 C.:
  • the treatment is carried out at 350 C. under 30 kg. per square centimeter pressure with a rate of feed of 8 v. v./ h. and a hydrogen recycle of 355 cubic meters per cubic meter of charge.
  • the treatment is carried out at 310 C. under 30 kg. per square centimeter pressure at a rate of feed of 8.5 v./ v./ h. and a hydrogen recycle of 235 cubic meters per cubic meter of charge.
  • a catalyst comprising nickel tungstate deposited on an alumina and silica support is used for the hydro-refining of an oily distillate as in Example II.
  • the results are apparent from Table IV.
  • the catalyst which has not undergone any pre-treatment in no way improves with the period of use under the operating conditions obtaining in the hydro-refining of oils.
  • a catalyst for said catalytic hydrogen action including an oxide of a metal selected from groups VI and VIII of the periodic table, said metal oxide catalyst being deposited on a supporting material therefor including an oxide of a metal selected from groups II and III and IV of the periodic table, activating and enhancing the effectiveness of said catalyst in a pre-treating step by subjecting said catalyst on said supporting material in the presence of hydrogen to the action of a petroleum distillate different from said lubricating oil fractions and including a substantial proportion of reactive and removable sulfur with consequent removal of sulfur from said petroleum distillate, and thereafter subjecting said lubricating oil fractions to the action of hydrogen in the presence of said thus activated and enhanced catalyst effecting said finishing improvement in the odor and color and stability of said fractions substantially in the absence of sulfur removal therefrom.
  • a catalyst for said catalytic hydrogen action including an oxide of at least one metal selected from groups VI and VIII of the periodic table, said metal oxide catalyst being deposited on a supporting material therefor including an oxide of at least one metal selected from groups II and III and IV of the periodic table, activating and enhancing the effectiveness of said catalyst in a pre-treating step by subjecting said catalyst on said supporting material in the presence of hydrogen to the action of a petroleum distillate including a substantial proportion of sulfur, and there after subjecting said lubricating oil fractions to the action of hydrogen in the presence of said thus activated and enhanced catalyst effecting said finishing said fractions substantially in the absence of sulfur removal therefrom.
  • the steps which comprise providing a catalyst for said catalytic hydrogen action including an oxide of a metal selected from groups VI and VIII of the periodic table, said metal oxide catalyst being deposited on a supporting material therefor including an oxide of a metal selected from groups 11 and III and IV of the periodic table, subjecting said catalyst on said supporting material to a pre-treating step in the presence of hydrogen to the action of a petroleum distillate including a substantial proportion of sulfur, and thereafter subjecting said lubricating oil fractions to the action of hydrogen in the presence of said thus pre-treated catalyst effecting said finishing said fractions.
