In one embodiment, a formed catalyst can comprise: a Ge-ZSM-5 zeolite; a binder comprising silica with 1 to less than 5 wt % non-silica oxides; less than or equal to 0.1 wt % residual carbon; 0.4 to 1.5 wt % platinum; and 4.0 to 4.8 wt % Cs; wherein the weight percentages are based upon a total weight of the catalyst. In one embodiment, a method of making a formed catalyst can comprise: mixing an uncalcined Ge-ZSM-5 zeolite and a binder to form a mixture; forming the mixture into a formed zeolite; calcining the formed zeolite to result in the formed zeolite having less than or equal to 0.1 wt % of residual carbon; ion-exchanging the formed zeolite with cesium; depositing platinum on the formed zeolite; and heating the formed zeolite to result in a final catalyst; wherein the final catalyst comprises 4.0 to 4.8 wt % cesium and 0.4 to 1.5 wt % platinum.

Method of preparing hydrocarbon aromatization catalyst, the catalyst, and the use of the catalyst

A method for forming a catalyst can comprise: heating a Ge-ZSM-5 zeolite powder at a temperature of 400 to 600&#xb0; C.; ion-exchanging the heat-treated zeolite powder with an alkali metal and impregnating the heat-treated zeolite powder with noble metal; heating the ion-exchanged, impregnated zeolite powder to a temperature of 250 to 350&#xb0; C.; mixing the second heat-treated zeolite powder with a solid silica binder and a colloidal silica binder to form a mixture, wherein if the solid silica has a purity of less than or equal to 66 wt % of silica oxide based on the total weight of the solid silica, then the mixture is free of an extrusion aide and the colloidal silica has a particle size of less than 20 nm as measured along a major axis; forming the mixture into a shaped body; and heating the shaped body to 100 to 350&#xb0; C. to result in the catalyst.

Hydrocarbon aromatization catalyst composition and method of formation

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.
