Catalytic cracking with zeolite-containing silica-alumina hydrogel catalyst

Patent ·
OSTI ID:6750806
;

A specially prepared zeolite-containing silica-alumina hydrogel gives a catalyst that is attrition resistant, more active catalytically, more selective and more stable. The hydrogel is prepared by steps including nozzle mixing of reactants to form a hydrogel, ion exchanging with ammonium, aluminum and rare earth ions, washing, drying and impregnating with rare earths.
