A catalyst composition, a process for producing the catalyst composition, and a hydroconversion process for converting a fluid stream comprising at least one saturated hydrocarbon to C.sub.6 to C.sub.8 aromatic hydrocarbons such as benzene, toluene, and xylenes are disclosed. The catalyst composition comprises a zeolite and a promoter. The process for producing the composition comprises the steps of: (1) combining a zeolite with a complexing ligand and a promoter compound under a condition sufficient to produce a modified zeolite; and (2) heating the modified zeolite to produce a promoted zeolite. The hydroconversion process comprises contacting a fluid stream with the catalyst composition under a condition sufficient to effect the conversion of a saturated hydrocarbon to a C.sub.6 to C.sub.8 aromatic hydrocarbon.
