Definitions

  • alumina catalysts containing, in addition to a noble metal from group VIII (generally platinum), a promoter metal which is the rhenium (US-A-3,415,737).
  • a promoter metal which is the rhenium
  • New races of catalyst are also known based on a noble metal from group VIII (generally platinum) and containing as promoter, for example tin or indium or thallium as promoter metal ( US-A-3,700,588 US-A-2,814,599).
  • platinum-rhenium catalyst has excellent stability but does not allow maximum selectivity to be observed. in obtaining good quality essences.
  • platinum-tin, or platinum-indium or platinum-thallium catalysts make it possible to obtain excellent selectivity, but the stability of these catalysts leaves something to be desired.
  • the object of the invention makes it possible to obtain quality gasolines for long periods (therefore with good stability), with very satisfactory selectivity by putting the charge first in contact with a platinum-rhenium catalyst and then with contact with a platinum catalyst, containing at least one promoter metal chosen from the group consisting of tin, indium and thallium.
  • a single reactor could be used comprising at least three separate catalyst beds, the first fixed catalytic bed through which the feedstock passes (upper bed in the case of a charge downdraft or lower bed in the case of '' an ascending charge current) consisting of the platinum and rhenium catalyst, the other beds consisting of catalyst containing platinum and at least one promoter metal chosen from thallium, indium and tin: these so-called other beds may each contain a different promoter.
  • At least two reactors in series, with fixed beds, placed side by side or superimposed, the first fixed bed reactor crossed by the charge containing one or more beds of the platinum and rhenium catalyst.
  • the other reactor (s) containing one or more beds of catalyst containing platinum and at least one other identical or different promoter metal.
  • platinum-tin is used, or else platinum, iridium and indium.
  • a catalyst containing platinum, said metal or said promoter metals and possibly iridium the same catalyst can be used in these beds but also different catalysts in each of these beds.
  • these different catalysts can be differentiated by the metallic concentration of platinum, of promoters, of iridium, by the nature of the promoter, by the presence or not of iridium, by the concentration of halogen, etc.
  • the charge flows successively through three reactors in series, with fixed catalyst beds, the first reactor containing a catalyst A and the second and third reactors each containing the same amount of catalyst B.
  • the specific surface and the pore volume of catalyst B are respectively 230 m 2 / g and 0.54 cm 3 / g).
  • column 1 gives the overall "material” balance obtained after 100 hours of operation. Also given in this table, for comparison, in column 1, the material balance obtained by using the only catalyst B in the three reactors.
