Abstract
A cracking catalyst contains a substantially inert core and an active shell, the active shell containing a zeolite catalyst and a matrix. The catalyst is formed by spray-drying a slurry containing water, substantially inert microspheres and a zeolite precursor and crystallizing zeolite in the active shell to create the cracking catalyst. Methods of using the cracking catalyst are also described.
