Beschreibung
Zusammenfassung:	The present invention relates to the use of an acid treatment method to remove heterocyclic nitrogen-containing compounds from a feedstream and then subjecting the feedstream having a reduced amount of nitrogen-containing compounds to catalytic cracking. L'invention concerne l'utilisation d'une méthode de traitement à l'acide, pour supprimer des composés contenant de l'azote hétérocyclique d'une charge, et pour soumettre la charge présentant une quantité réduite de composés contenant de l'azote, à un craquage catalytique.
