Definitions

  • Isobutanes are removed with a separation step, and the remainder of the heavy naphtha feed is treated with a ring cleavage catalyst such as an L-zeolite.
  • a ring cleavage catalyst such as an L-zeolite.
  • the instant invention does not require a separation step, and hydrocracking with a high activity zeolite is employed for upgrading purposes, rather than isomerization with a solid acid catalyst.
  • Figure 1 illustrates product yield v. conversion of feed for single and dual catalyst systems.
  • Figure 2 illustrates hydrogen consumption v. conversion of feed for single and dual catalyst systems.
  • Figure 12 illustrates yields by volume of C 3 -C 5 products v. percent noble metal catalyst in reactor.
  • the feedstock for the process can be straight-run, thermal or catalytically cracked naphtha. Naphthas derived from shales, tar sands and coal may also be treated. Typically naphthas boil at 25° to 260°C. While the process can accept any naphtha in this boiling range, it generally shows its greatest advantage on feedstocks which boil between 50° and 260°C. Since one of the features of the invented process is saturation of aromatic hydrocarbons, the feedstock naphtha will contain aromatic hydrocarbons, generally from 1 to 40 volume per cent. In order to obtain full benefit from the isomerization and cracking functions of the process the feed will also contain from 5 to 40 per cent n-paraffins. Preferred feedstocks will boil between 70° and 250°C and will contain 5 to 25 percent aromatic hydrocarbons and 10 to 30 percent n-paraffins.
  • both a catalyst having a aromatics saturation component and a catalyst which comprises an acidic component for cracking are employed.
  • the cracking component is frequently PtPd USY/Al 2 O 3 , in highly dealuminated form or a form in which the acid sites are exchanged with a counterion.
  • the USY is of very low acidity.
  • the aromatics saturation function is provided by a transition metal or combination of metals.
  • Noble metals of Group VIIIA of the Periodic Table, especially platinum or palladium are preferred. Base metals of Groups IVA, VIA and VIIIA may be used at very high pressures, however.

Abstract

La présente invention concerne un procédé d'hydrocraquage de charge de naphta lourd. On a observé une amélioration de la sélectivité du procédé d'hydrocraquage lorsque la saturation d'aromatiques et les réactions d'hydrocraquage ont été dissociées. Cette avantage a été observé dans l'hydrocraquage réalisé soit avec des catalyseurs de métaux nobles soit avec des métaux de base. La sélectivité amélioré a été observé à la fois dans une opération basse pression et une opération pression standard. Une diminution de la quantité de gaz léger (C1-C4) et une augmentation de la quantité de produit liquide obtenu ont également été observées. La dissociation de la saturation aromatique des réactions d'hydrocraquage a également participé à l'amélioration significative de l'exploitabilité du procédé (c.-à-d., tendance à l'emballement diminuée), contrôlabilité et diminution de la vitesse de désactivation du catalyseur.
