T 2310 A B S T R A C T HYDROGENATION CATALYST AND PROCESS A catalyst composition comprising one or more Group VIII noble metal(s) on a support wherein the support comprises a zeolite prepared by contacting a starting Y-type zeolite having a unit cell size of less than 24.65 angstroms, a silica to alumina molar ratio greater than 5, and an alkali(ne earth) metal content of less than 0.3 weight percent (basis metal) with one or more aqueous solution(s) comprising alkali(ne earth) metal ions under conditions sufficient to provide a final alkali(ne earth) metal content (measured in terms of gram equivalent weight per gram of zeolite) of at least 1.5 times greater than the alkali(ne earth) metal content (measured in terms of gram equivalent weight per gram of zeolite) of the starting zeolite. The catalyst composition can be used in a process for the hydrogenation of hydrocarbon feedstocks containing hydrogenatable components and which have a boiling range between 125 and 625°C.
