Definitions

  • Hydroforming is a well-known process for producing high octane motor gasolines from low octane petroleum naphthas.
  • the low octane petroleum naphtha is contacted at elevated temperature in the presence of hydrogen with a catalyst capable of converting naphthenes into aromatics to give a product of greatly increased octane number.
  • a hydroforming process that has been widely adopted uses a platinumcontaining catalyst and such a process will hereinafter be referred to as Platforming.
  • Platforming The catalytic reformate of such a process will hereinafter be referred to as Platformate. It has long been known that the octane number of a catalytic reformate can be increased by thermal reforming, and it has recently been proposed to apply this principle to the product of the Platforming process.
  • a catalytic reformate is separated into a high boiling fraction and a low boiling fraction, the two fractions are subjected to thermal reforming separately, the low boiling fraction being reformed at a greater severity than the high boiling fraction, and the products of the thermal reforming operations are blended to produce a high octane gasoline.
  • the cut point between the low boiling and high boiling fractions of the catalytic reformate should preferably lie within the range 110 to 150 C.
  • the thermal reforming operations are preferably carried out at temperatures within the range 1,000 to 1,200 F. and at a pressure within the range 200 to 1,200 p.s.i.g., and the conditions in the two operations are preferably such that conversion to C and lighter on the low boiling fraction is in the range 20% to 35% wt. and on the high boiling fraction 5% to 20% wt.
  • the process according to the invention has the advantage that it is possible to subject the low boiling fraction to the severe reforming conditions necessary to produce "ice under the following conditions:
  • a Platformate of 82 octane number (Research) was obtained and was distilled in a 10 plate continuous column to give a light Platformate of 130 C.
  • the light Platformate (75 octane number) was reformed at 750 p.s.i.g. and at 1,060 F. to give the following product distribution:
  • the gasoline (35% wt. on total Platformate) had an octane number of iso-octane-f-0.8 m1. TEL/USG octane number (Research).
  • Naphtha is fed through line 1 to a catalytic reformer 2 and reformed debutanized gasoline passes via line 3 to the middle of a distillation column 4, which separates the gasoline into two fractions with a cut point in the region of -150 C.
  • the light gasoline taken off overhead through line 5 has a relatively low octane number and is thermally reformed in reformer 6 at a relatively high severity.
  • the heavy gasoline withdrawn from the column 4 through line 7 is thermally reformed in reformer 8 at a lower severity, since it has initially a relatively high octane number.
  • the products from both thermal reformers are re-run and debutanized and pass via lines 9 and 10 respectively to a common line 11 for blending and storage.
  • a process for producing gasoline of increased octane number from a liquid catalytic reformate, which reformate is a product of a hydroforming process in which is used a platinum-containing catalyst, comprising separating the catalytic reformate into a high boiling liquid fraction and a low boiling liquid fraction, thermally reforming two fractions separately, each at a temperature within the range l000 to 1200 F. and a pressure within the range 200 to 1200 p.s.i., but at different severities, the low boiling fraction being reformed at the greater severity, and blending the products of the thermal reforming operations.
