Title (EN) GASOLINE SULFUR REDUCTION CATALYST FOR FLUID CATALYTIC CRACKING PROCESS
(FR) CATALYSEUR RÉDUISANT LA TENEUR EN SOUFRE DE CARBURANT POUR PROCESSUS DE CRAQUAGE CATALYTIQUE FLUIDE
Abstract: front page image
(EN)ABSTACT OF THE DISCLOSURE A catalytic cracking catalyst composition is disclosed that is suitable for reducing the sulfur content of catalytically cracking liquid products, in particularly gasoline products, produced during a catalytic cracking process. Preferably, the catalytic cracking process is a fluidized catalytic cracking (FCC) process. The composition comprises zeolite, zinc and at least one rare earth element having an ionic radii of less than 0.95 Å at a coordination number of 6. Preferably, zinc and the rare earth element are present as cations that have been exchanged on the zeolite. The zeolite is preferably a Y-type zeolite.
(FR)L'invention concerne une composition de catalyseur de craquage catalytique conçue pour réduire la teneur en soufre de produits liquide de craquage catalytique, en particulier des produits de type carburant, produits pendant un processus de craquage catalytique, de préférence un processus de craquage catalytique fluidisé (NCC). La composition comprend de la zéolite, du zinc et au moins un élément de terres rares dont les rayons ioniques sont inférieurs à 0,95 angström au niveau d'un nombre de coordinations de 6. De préférence, le zinc et l'élément de terres rares sont présents sous la forme de cations qui ont été échangés sur la zéolite. La zéolite est de préférence une zéolite de type Y.
