Abstract: A method for forming a catalyst can comprise: heating a Ge-ZSM-5 zeolite powder at a temperature of 400 to 600° 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° 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° C. to result in the catalyst.

Abstract: A method of forming a zeolite shaped body is carried out by preparing an aqueous mixture containing a zeolite, a silica binder material and an extrusion aid. The extrusion aid is at least one of PVAc-PVA1 (80-89) and polyacrylamide. The mixture is formed into a body having a selected shape. The shaped body is heated to form the zeolite shaped body.

Abstract: 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.

Abstract: The invention provides a process for selective hydrogenation of alkynes and other unsaturated hydrocarbons, such as acetylene and diolefins, with a catalyst comprising Pd and, optionally, at least one metal from the IA, IB, IIIA, IIIB, VB, or VIIIB Groups, where the metals are supported on a porous material, such as titania. If the process is in the absence of carbon monoxide (CO) in the feed, at least one metal from the IA, IB or IIIA Groups should be present in the catalyst, e.g., potassium, boron or silver. If the carbon monoxide (CO) is present in the feed, the catalyst consists essentially of Pd supported on a porous material, such as titania.
