Definitions

  • Catalytic cracking and hydroforming are among the processes which contribute to the production of high octane gasolines.
  • a petroleum feedstock boiling above the gasoline boiling range is cracked in the presence of a catalyst to produce hydrocarbons boiling in the gasoline boiling range, while in the hydroforming process, petroleum naphthas that have a low octane number are contacted at elevated tempera- 1 ture in the presence of hydrogen with a catalyst capable of converting naphthenes into aromatics to give a product of greatly increased octane number.
  • a hydrotorming process that has been widely adopted uses a platinumcontaining catalyst and such a process will hereinafter be referred to as platinum reforming.
  • thermal. reforming treatment should be carried out will depend upon the properties of the blend and those required in the final product, but in general the following conditions will be found to be suitable:
  • a high octane gasoline comprising 55% by volume of a light catalytically cracked gasoline having a boiling range of C to 100 C., and 45% by volume of a 45% Weight platinum reformate residue.
  • the associated light platinum reformate and heavy catalytically cracked gasoline when blended together give a gasoline of 82 Research octane and a volatility of 50.5% evaporated at 100 C. Inspection data on these materials are given in the following table.
  • This blend was thermally reformed at 750 p.s.i.g and 1050 F. to a conversion of 19% Weight C and lighter,
  • TEL/1G which comprises separating a platinum reformate into lower boiling fraction constituting between 40% and 60% by weight of the reformate and having a relatively low octane number and high volatility, and a higher boiling remainder constituting between 60% and 40% by weight of the reformate and having a high octane number and low volatility; separating a catalytically.
  • cracked gasoline into a lower boiling fraction having an end boiling point between 80 and C., and a higher boiling remainder having a relatively high octane number and low volatility and an initial boiling point between 80 and 120 C.; blending together said lower boiling fraction of said platinum reformate and said higher boiling remainder of said catalytically cracked gasoline;
