Abstract

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.
