| Title of Invention | A NON-MACROPOROUS ZEOLITI FLUID CATALYTIC CRACKING CATALYST AND METHOD FOR MAKING THE SAME |
|---|---|
| Abstract | A non-macroporous zeolitic fluid catalytic cracking catalyst produced the steps comprising: (a) forming a aqueous slurry containing (i) hydrated kaolin clay, metakaolin or mixtures thereof, (ii) a calcined aluminum source and (iii) binder, said calcined aluminum source having an incipient slurry point of less than 57% solids;(b) spray drying the aqueous slurry to obtain microspheres;(c) calcining the microspheres obtained in step (b) at a temperature and for a time sufficient to convert hydrated kaolin clay in the microspheres substantially to metakaolin, but insufficient to cause metakaolin or hydrated kaolin to undergo the characteristic kaolin exotherm and to provide microspheres of calcined kaolin having a ratio of metakaolin to calcined aluminum source in excess of 1:1;(d) mixing the microspheres obtained in step (c) with sodium silicate and water to obtain an alkaline slurry;(e) heating the slurry of microspheres of calcined kaolin to a temperature and for a time sufficient to crystallize at least about 50% by weight Y-faujasite in the microspheres. |
