Abstract
Novel catalyst bases are described which are prepared by hydrothermally treating an ammonium ion exchanged sodium Y zeolite followed by low pH ammonium ion exchange to produce highly crystalline zeolite catalyst base. Catalysts incorporating such novel zeolite catalyst bases, as well as hydrocracking and fluid catalytic cracking processes for the production of gasoline products utilizing catalysts incorporating such novel catalyst bases, are also described.
