Abstract: Catalysts for hydrogenation of CO2 to dimethyl ether. These catalysts comprise 0.1-10 wt % per total catalyst weight of a catalytic material containing Pd (e.g. metallic palladium), 0.05-5 wt % per total catalyst weight of a promoter containing Ca (e.g. metallic calcium), as well as 85-99 wt % of CeO2 as a catalyst support. Methods of preparing and characterizing the catalysts as well as processes for catalyzing the hydrogenation of CO2 to dimethyl ether and other byproducts such as methanol, carbon monoxide, and methane portrayed by reactant conversion, product selectivity, and catalyst stability are disclosed.

Abstract: A catalyst composition for methanol partial oxidation for hydrogen production includes a zinc metal supported on a reducible porous oxide carrier. The zinc metal can vary from about 0.1 wt. % to about 30 wt. % of the catalyst composition. The catalyst composition can be used to produce hydrogen from methanol at high yield and with a low selectivity towards carbon monoxide (CO) production. The reducible porous oxide carrier includes a mechanical mixture of CeO2 and ZrO2.
