Definitions

  • ABSTRACT Destructive hydrogenation of lubricating oils by hydrogenating, hydrocracking and isomerizing oils, which have not been conditioned, in the presence of at least two layers of catalysts in a single reaction, to obtain a synergistic effect of their hydrogenating, hydrocracking, and isomerizing functions.
  • the present invention refers to a procedure and reactor for the destructive hydrogenation of lubricating oils, in order to obtain lubricants, in one or more cuts, having a high viscosity index.
  • Destructive hydrogenation of lubricating oils eliminates the above disadvantages and achieves relatively high yields of hydrotreated products with a substantial increase in the viscosity index, without conditioning of the feedstock, by means of two or more distinct layers of two specific and different catalysts, set out in the same reactor; the first catalyst has the prevalent function of hydrogenation, and the second one has the prevalent function of hydrocracking-isomerization, functions that are carried out in relation to the active element composition of the catalysts and/or acidity of their support ensuring taking over of heat from the reaction of hydrogen and/or hydrocarbon fractions.
  • the reactor for this procedure is a cylindrical vessel made up of two or more successive reaction zones in which there are two or more successivelit sive and distinct layers, even or uneven, formed of two catalysts, specific or different. Separating the zones are one or more sieves of the fractionating-tray type without downeomers; a coaxial cooling system formed of two or more pipelines for feeding every reaction zone in the cooling point, with hydrogen and/or hydrocarbon fractions is also provided.
  • FIG. 1 is a schematic diagram of the reactor operating with only two catalyst layers
  • FIG. 2 is a graph showing results obtained.
  • FIG. 2 represents the variation of the viscosity index and the viscosity of hydrogenated oil, obtained in accordance with the invention (curves [1 and as compared to the same elements obtained with type A catalysts (curves -0-) and and B type (curves A and catalysts when used separately in the reactor.
  • Catalyst A is a nickelmolybdenum catalyst
  • catalyst B is a nickeltungsten catalyst.
  • SPECIFIC DESCRIPTION SPECIFICEXAMPLES Example 1
  • the feedstock, a distilled oil of naphthenic-aromatic type, having the viscosity: 30E/50C and viscosity index: 45, together with the addition and recycle of hydrogen, is fed to the reactor with a space velocity of 0.5 vo1./vol. hr., under a pressure of atm. and a recycle ratio of 1500 m3/m3 STP and are passed downfiow through two distinctive layers of specific and different catalysts of A and B type.
  • the liquid product is stripped in order to remove the hydrogen sulphide and gases, and then fractionated to separate the light and medium products.
  • the bottom product lubricating oil is then vacuum-distilled in order to obtain different qualities of oils.
  • the lubricating oil fraction obtained when operating at 415C temperature has the characteristics given below in Table 1.
  • Viscosity index Viscosity E/50C 9 TABLE 4 With B-type catalyst Temperature, "C (reaction) Yield, wt.
  • Viscosity index Viscosity, E/50C Table 5 shows that the procedure followed according to the invention yeidls a product of the highest viscosity, at the lowest operating temperature for an oil of vistemperature, C
