Method of CO and/or CO2 hydrogenation using doped mixed-metal oxides

A method of conducting a reaction process comprising:

• delivering a reactant gas mixture comprising a carbon oxide and a hydrogen agent;
• providing a catalyst comprising a deposited metal supported on a mixed-metal oxide, wherein the deposited metal comprises a transition metal, an alkali metal, an alkaline earth metal, a noble metal, or mixtures thereof, and wherein the mixed-metal oxide comprises a doped perovskite, a doped pyrochlore, a doped brownmillerite, or mixtures thereof wherein:
• the doped perovskite has a perovskite composition A1-xA′xB1-yB′yO3-z wherein,
• A is one or more of a lanthanide series metal, Ca, Y, or mixtures thereof,
• A′ is a Group 1 metal, a Group 2 metal, a Group 3 metal, or mixtures thereof,
• B is one or more of a transition metal, Ga, or mixtures thereof,
• B′ is one or more of a noble metal,
• 0≦x≦1, 0≦y≦1, x+y>0, and z is a number that renders the composition charge neutral,
• the doped pyrochlore has a pyrochlore composition A2-xA′xB2-yB′yO7-z wherein,
• A is one or more of a lanthanide series metal, Ca, or mixtures thereof,
• A′ is one or more of a Group 1 metal, a Group 2 metal, or mixtures thereof,
• B is one or more of a transition metal, Si, Ge, Sn, Pb, Ce or mixtures thereof,
• B′ is one or more of a noble metal,
• 0≦x≦1, 0≦y≦1, x+y>0, and z is a number that renders the composition charge neutral,
• the doped brownmillerite has a brownmillerite composition A2-xA′xB2-yB′yO5-z wherein,
• A is one or more of an alkaline earth metal,
• A′ is one or more of a lanthanide series metal, a Group 3 metal, or mixtures thereof,
• B is one or more of a transition metal, a Group 13 metal, or mixtures thereof,
• B′ is one or more of a lanthanide series metal, a noble metal, a Group 3 metal, or mixtures thereof,
• 0≦x≦1, 0≦y≦1, x+y>0, and z is a number that renders the composition charge neutral;
• and
• contacting the reactant gas mixture and the catalyst and maintaining the reactant gas mixture and the catalyst at conditions of temperature, pressure and gas flow rate to generate a reaction and produce a gaseous mixture comprised of a product, the product comprising carbon from the carbon oxide and at least some portion of the hydrogen agent, and the product comprising an alcohol, an aldehyde, a ketone, an ester, an oxo-product, or mixtures thereof, and the gaseous mixture having at least a 15% product selectivity for the product.
