ZSM-5 zeolite particles into which 0.6 weight per cent or less of gallium oxide has been incorporated by surface-contact transfer, may exhibit very high activity in the aromatization ofn-butane. In some cases, the yield in aromatics is as high as that obtained with the hybrid catalyst wherein the cocatalyst is prepared by evaporation of a solution of gallium nitrate in Ludox colloidal silica.
