A process and catalyst are provided for the catalytic cracking of a hydrocarbon feedstock to catalytic cracking conversion products comprising the steps of contacting the hydrocarbon feedstock at catalytic cracking conditions with a catalytic cracking catalyst. The catalytic cracking catalyst is prepared by modifying a base catalyst comprising a crystalline molecular sieve and a binder by combining the base catalyst with an ion exchange solution comprising at least one trivalent cation, a trivalent cation complexing agent, and a hydroxide-producing component, wherein the ion exchange solution has a pH ranging from about 4 to about 8, and producing an ion exchanged catalyst and excess ion exchange solution. The modified catalyst is then separated from said excess ion exchange solution.
