Process for the preparation of a catalyst and a catalyst comprising enhanced mesoporosity is provided herein. Thus, in one embodiment, provided is a particulate FCC catalyst comprising 2 to 50 wt % of one or more ultra stabilized high Si02/A1203 ratio large pore faujasite zeolite or a rare earth containing USY, 0 to 50 wt % of one or more rare-earth exchanged large pore faujasite zeolite, 0 to 30 wt % of small to medium pore size zeolites, 5 to 45 wt % quasi-crystalline boehmite 0 to 35 wt % microcrystalline boehmite, 0 to 25 wt % of a first silica, 2 to 30 wt % of a second silica, 0.1 to 10 wt % one or more rare earth components showiomg enhanced mesoporosity in the range of 6-40 nm, the numbering of the silica corresponding to their orders of introduction in the preparation process.
An FCC catalyst composition comprising a first zeolite of about 2 to about 50 wt % selected from the group of one or more ultra stabilized or rare earth exchanged ultra stabilized high SiO2/Al2O3 ratio Y, optionally a second zeolite of 0 to about 50 wt % of one or more rare-earth exchanged Y zeolite, optionally 0 to 30 wt % of small to medium pore zeolite, about 5 to about 45 wt % quasicrystalline boehmite, about 0 to about 35 wt % microcrystalline boehmite, a first silica of about 0 to about 20 wt %, a second silica of about 2 to about 30 wt %, about 0.1 to about 10 wt % one or more rare earth components as oxide and the balance clay.
