Definitions

  • This invention relates to the catalytic reforming of petroleum hydrocarbons in order to increase their suitability for use as motor fuels. More particularly the invention relates to improvements in the so-called Platforming process wherein hydrocarbons are contacted in the presence of hydrogen with a platinum-containing catalyst.
  • Platforming is capable of producing a considerable increase in the octane number of straight-run petroleum feedstocks in the motor gasoline boiling range, but it has recently been noted that the octane number of the Platformate falls off rapidly on exposure to light and air, and that this effect cannot be prevented by the use of oxidation inhibitors.
  • a similar loss of octane number is not shown by catalytically cracked or steam cracked n gasoline, so that the component or components causing the octane number loss appear to be formed by the reforming operation itself.
  • the extent of the loss in the octane number in respect of a typical Platformate is illustrated in the following Table 1, and compared with the loss for samples of catalytically cracked and steam cracked gasolines.
  • the preferred catalyst is a sulphur resistant hydrogenation catalyst particularly one or more of the sulphides of a group VI or group VIII metal, for example a mixture of nickel and tungsten sulphides.
  • a sample of debutanised Platformate having a research octane number of 87.1 was "ice exposed to air and light for 24 hours, after which time the research octane number had decreased to 81.5.
  • the Platformate After hydrogenation, the Platformate had a research octane number of 86.5 which after 96 hours exposure to ⁇ air and light had only decreased to 86.1.
  • the fraction of Platformate boiling between 100 and 138 C. is separated and subjected to mild hydrogenation as above described, the hydrogenated fraction being then blended back with the remaining portions of the Platformate.
  • the hydrogenation treatment in accordance with the invention may be carried out as an operation separate and distinct from the Platforming operation. If desired however, it may be carried out as part of a continuous process with the Platforming operation. In this case, the product from the Platforming operation is cooled and if necessary reduced in pressure before being passed to the hydrogenation reactor.
  • the products from a catalytic reformer 1 include liquid debutanised reformate and hydrogen-rich gas.
  • the former is fed via line 2 to a reformate splitter 3 where it is fractionated into three streams, the middle of which contains substantially all the components giving rise to the lightcatalysed octane number loss.
  • This stream is passed via line 4 to a hydrogenation plant 5 supplied through line 6 with the hydrogen-rich gas from the catalytic reformer 1. After hydrogenation, the stream is recombined with the splitter overheads and splitter bottoms which are fed via lines 7 and 8 respectively.
  • the dotted continuations of thesplitter overheads and the splitter bottoms lines (9 and 10 respectively) illustrate a possible variant of the process in which the splitter streams are not recombined.
  • the dotted line 11 by-passing the reformate splitter illustrates a further variant in which the total debutanised reformate is hydrogenated without previous splitting.
  • a process for reducing loss of octane number due to exposure to light and air of a platinum reformate obtained by contacting a straight-run petroleum feedstock boiling in the gasoline range with a reforming catalyst containing platinum which comprises contacting the platinum reformate in the presence of hydrogen with a hydrogenation catalyst at a temperature of 300 to 500 F. and at a pressure of 0 to 500 p.s.i.g.
  • a process for reducing loss of octane number due to exposure to light and air of a platinum reformate obtained by contacting a straight-run petroleum feedstock boiling in the gasoline range with a reforming catalyst containing platinum which comprises separating from the platinum reformate a fraction having a boiling range of approximately 100 to 138 C., contacting said fraction in the presence of hydrogen with a hydrogenation to 4000 s.c.f./b.
  • the catalyst comprises at least one sulphide of a metal selected from groups VI and VIII of the periodic table.
