Process for the preparation of a particulate FCC catalyst and a particulate FCC catalyst increased contaminants resistivity being essentially free of clay. Thus, in one embodiment, provided is a particulate FCC catalyst composition comprising one or more zeolites, at least one alumina component, at least one silica component, and being essentially free of clay. In a further embodiment, it is provided a particulate FCC catalyst composition comprising at least two different types of alumina and at least one silica component and being essentially free of clay. The alumina components can be selected from the group of peptizable quasicrystalline boehmite, non-peptizable microcrystalline boehmite phase, non-peptizable alpha phase or non-peptizable alumina containing gamma phase or non-peptizable alumina containing chi phase or gibbsite alumina. The silica component can be selected from the group of low sodium stabilized colloidal silica and acid or low sodium or ammonia stabilized colloidal silica or ploy silicic acid.
A particulate FCC catalyst composition with increased contaminants resistivity comprising about 1 to about 50% one or more zeolites, about 1 to about 45 wt % quasicrystalline boehmite, about 1 to about 45 wt % microcrystalline boehmite, greater than about 0-40 wt % non-peptizable alumina comprising gamma or alpha or chi phase alumina or gibbsite, about 1 wt % to about 20 wt % sodium stabilized silica, and about 0-20 wt % low sodium or acid or ammonia stabilized colloidal silica or poly silicic acid and essentially free of clay.
A particulate FCC catalyst composition with increased contaminants resistivity comprising one or more zeolites, at least one alumina component, at least one silica component, and being essentially free of clay.
