We disclose an aromatization catalyst, prepared by a process comprising impregnating an L zeolite with platinum acetylacetonate. We also disclose a method of aromatizing a light naphtha, comprising reacting the light naphtha in the presence of an aromatization catalyst prepared by the process referred to above. The process of preparing the aromatization catalyst can also include loading the L zeolite with a Group IVB metal, a rare earth metal, or a lanthanide, such as titanium or thulium.
