Zeolite microsphere FCC catalysts having a novel morphology comprising a macroporous matrix and crystallized zeolite freely coating the walls of the pores of the matrix. The catalysts are formed from microspheres containing a metakaolin and kaolin calcined through its exotherm, the latter calcined kaolin being derived from a kaolin having a high pore volume. Kaolin having a high pore volume can be a pulverized ultrafine kaolin or a kaolin which has been pulverized to have an incipient slurry point less than 57 % solids.
Catalyseurs de craquage FCC à base de microsphères de zéolite possédant une nouvelle morphologie composée d'une matrice macroporeuse et de zéolite cristallisée revêtant librement les parois des pores de la matrice. Ces catalyseurs sont constitués par des microsphères contenant un métakaolin et du kaolin calciné par réaction exothermique et obtenu à partir d'un kaolin présentant un volume important de pores. Ce kaolin présentant un volume important de pores peut consister en un kaolin ultrafin pulvérisé ou en un kaolin pulvérisé de façon que son point de transformation en semi-liquide est, à son début, d'une teneur inférieure à 57 % de solides.
