A catalyst useful in cracking of hydrocarbon feedstock comprising particulate material composed of at least 70 weight percent zeolite and the remainder substantially composed of silica sol, alumina sol or mixtures thereof; wherein the particulate material has a kinetic conversion activity of at least about 3; and compositions for fluid catalytic cracking of petroleum feedstock comprising said catalyst and a second particulate material having a kinetic conversion activity of less than 3 wherein said catalyst composition having a kinetic conversion activity of at least about 2.
L'invention concerne un catalyseur servant à fissurer une charge d'alimentation hydrocarbure composée d'un matériau particulaire composé d'au moins 70 % par poids de zéolite, le reste étant essentiellement composé de sol de silice, de sol d'alumine ou encore de mélanges de ceux-ci dans lesquels le matériau particulaire présente une activité de conversion cinétique d'au moins 3 environ et des compositions de fissure catalytique fluide de charge d'alimentation de pétrole composé dudit catalyseur et d'un second matériau particulaire présentant une activité de conversion cinétique inférieure à 3 dans laquelle ladite composition de catalyseur possède une activité de conversion cinétique d'au moins 2 environ.
