Abstract

A method of deoxygenating a feedstock, comprising at least one oxygenated organic compound, to form a hydrocarbon product, comprising the steps of: contacting the feedstock with a catalyst under conditions to promote deoxygenation of the at least one oxygenated compound, wherein the catalyst comprises a mixed metal oxide of the empirical formula: (M2)y(M1)O—ZnO—(Al2O3)x is disclosed. The invention is useful in the production of renewable fuels, such as renewable diesel, and jet fuel.

Description

FIELD OF THE INVENTION

[0001] The present disclosure relates to methods, compositions, and uses of decarbonylation and decarboxylation catalysts to produce renewable hydrocarbons.BACKGROUND OF THE INVENTION

[0002] Biofuels are fuels produced from biomass—organic matter derived from living, or recently living organisms. Biofuels, as opposed to fossils fuels, are renewable resources and can provide a sustainable supply of fuel. However, compared to fossil fuels, biomass is more functionalized and requires defunctionalization in order to make it readily usable with existing fuel consumption technologies1.

[0003] Biodiesel, a first generation biofuel, is produced using a transesterification process resulting in a fuel that is chemically different from petrodiesel, because it contains oxygen atoms in the form of a fatty acid methyl ester. This results in a type of diesel fuel, which, though environmentally more friendly than petrodiesel fuel, corrodes a standard internal combustion diesel engi...

Embodiment Construction

[0030]In one aspect, the present invention provides a method of deoxygenating a feedstock, comprising at least one oxygenated organic compound, to form a hydrocarbon product, comprising the steps of contacting the feedstock with a catalyst under conditions to promote deoxygenation of the at least one oxygenated compound.

[0031]In one aspect, the catalyst comprises a mixed metal oxide of the empirical formula:

(M2)y(M1)O—ZnO—(Al2O3)x

wherein M1 is a metal selected from the group consisting of Ag, Au, Co, Cr, Cu, Fe, Ir, Mo, Ni, Os, Pd, Pt, Rh, Ru, and W; M2 is a metal selected from the group consisting of Ag, Au, Co, Cr, Cu, Fe, Ir, Mo, Ni, Os, Pd, Pt, Rh, Ru, and W, but is not the same as M1; x is 0 or 1; and y is 0 or 1.

[0032]In one aspect, M1 is selected from the group consisting of Co and Ni. In one aspect, M2 is selected from the group consisting of Ag, Au, Co, Ir, Ni, Os, Pd, Pt, Rh, and Ru.

[0033]In one aspect, the catalyst comprises a mixed metal oxide of the formula MO—ZnO—(Al2...
