The present invention is for a catalyst, a process for making the catalyst and a process for using the catalyst in aromatization of alkanes having three to five carbon atoms per molecule, such as propane, to aromatics, such as benzene, toluene and xylene. The catalyst is an aluminum-silicon zeolite having a silicon to aluminum atomic ratio (Si:Al) greater than 15:1, such as MFI or ZSM-5, on which germanium, aluminum and a noble metal, such as platinum, have been deposited. The catalyst may be bound with magnesia, alumina, titania, zirconia, thoria, silica, boria or mixtures thereof. The aluminum and germanium may be deposited simultaneously on the zeolite.

Zeolite catalyst with deposited germanium, aluminum and platinum for aromatization of alkanes, process of making and process of using thereof

A shell impregnated catalyst of Pd&mdash;Au produced on a silica support by impregnating the support with aqueous solutions of palladium and gold salts or acids and thereafter precipitating water insoluble compounds of Pd and Au on the support with alkali metal silicate or hydroxide fixing agents, then drying the support which has precipitated compounds of Pd and Au on its surface and reducing the surface precipitated compounds of Pd and Au until substantially all of the Pd and Au contents are reduced to a free metal state, after which the catalyst precursor is impregnated with potassium acetate and then dried. Improvements in the catalyst are realized by certain factors in process and composition.
