| Abstract: | A process for the preparation of fluid catalytic cracking (FCC) catalyst by preparing NH4Y Zeolite with aqueous solution of ammonium salt by known methods to achieve silica alumina ratio of 80:20 having concentration range of 1 to 3N at a temperature in the range of 70-100 deg C to obtain NH4Y Zeolite, heating the above said NH4Y Zeolite at a temperature of 380-820 deg C for a period in the range of 0.1 to 12 hrs. in presence of steam to obtain dealuminated Zeolite Y, treating the dealuminated Zeolite Y with mineral acid with concentration range of 0.1 to6N, dispersing the 30% dealuminated Zeolite Y into 40% active silica alumina matrix having silica alumina ratio of 80:20 to obtain dispersed dealuminated Zeolite Y, stirring the above said dispersed dealuminated Zeolite Y mixture and adding 20% of Kaolin, adding 10% of peptized alumina hydrate at a pH range between 6-7.5, filtering, washing, drying & calcining at temperature ranging 400 to 600 deg C to obtain catalyst, treating the catalyst obtained with a salt of lanthanum solution having 2-3 wt% lanthanum & drying the rare earth exchanged catalyst for 2-4 hrs at a temperature of 80 to 150 deg C, calcining the catalyst at temperature 400-600 deg C for 2 to 3 hrs. & sieving to obtain 100-200 mesh size particle catalyst. |
