A FCC catalyst having improved coke selectivity and a FCC process for converting hydrocarbon feedstocks to lower boiling products. The catalyst comprises a crystalline aluminosilicate zeolite, gibbsite, rare earth metal compound and a silica matrix prepared from at least one of a silica sol made by an ion-exchange process and an acidic silica sol prepared by mixing sodium silicate, an acid and an aluminum salt of an acid.
Catalyseur CCF possédant une sélectivité améliorée pour le coke et procédé CCF pour convertir des hydrocarbures en produits à température d'ébullition plus basse. Le catalyseur renferme une zéolite d'aluminosilicate cristallisé, de la gibbsite, un métal des lanthanides et une matrice de silice, préparée à partir d'au moins un sol de silice, obtenu par un procédé d'échange ionique, et d'un sol de silice acide préparé en mélangeant du silicate de sodium, un acide et un sel d'aluminium d'un acide.
