Abstract
A novel shell-coated FCC catalyst is disclosed wherein the shell is a mixture of at least one refractory metal oxide or silicate or precursor thereof (preferably clay) having a particle size of 0.3 to 5 microns and an inorganic refractory binder (preferably silica) having a particle size of less than 0.01 microns and the core is a zeolite-containing microsphere. FCC with the shell coated catalyst is also disclosed
