CA 2634526
Novel catalytic compositions for cracking of crude oil fractions are disclosed. The catalytic compositions comprise a basic material. When used in a cracking process, preferably a FCC process, the resulting LCO and HCO fractions have desirably low aromatics levels. Further disclosed is a one- stage FCC process using the catalytic composition of the invention. Also disclosed is a two-stage FCC process for maximizing the LCO yield.
L'invention concerne de nouvelles compositions catalytiques de craquage de fractions de pétrole brut. Les compositions catalytiques contiennent un matériau de base. Lorsqu'elles sont utilisées dans un procédé de craquage, de préférence un procédé FCC, les fractions de LCO et de HCO présentent idéalement de faibles niveaux aromatiques. L'invention concerne également un procédé FCC à un étage utilisant la composition catalytique de l'invention. Elle concerne enfin un procédé FCC à deux étages destiné à maximiser le rendement de LCO.
