Title
(EN) MAGNETICALLY SEPARATED EQUILIBRIUM CATALYST FOR SPECIALIZED CRACKING
(FR) CATALYSEUR D'EQUILIBRE A SEPARATION MAGNETIQUE DESTINE AU CRACKAGE SPECIALISE
Abstract
(EN)
Disclosed is a method for improving fluid cracking catalyst performance by increasing metal contamination incrementally while cracking two different feedstocks that have different concentrations of metal contaminants. The relative amount of metal contamination is controlled by magnetic separation. The incrementally increased cracking catalyst is used in cracking a second feedstock.
(FR)
L'invention concerne un procédé permettant d'améliorer les performances du catalyseur de crackage fluide en augmentant de manière incrémentielle la contamination métallique, tout en procédant au crackage de deux flux d'alimentation différents dont les concentrations en contaminants métalliques sont différentes. La quantité relative de contamination métallique est déterminée par séparation magnétique. Le catalyseur de crackage à augmentation incrémentielle est utilisé pour le crackage d'un second flux d'alimentation.
