Abstract
A catalytic method for producing gaseous products from a fuel and a gaseous reagent having the steps of: providing a catalyst and the fuel to a reactor vessel such that the catalyst and the fuel are in fluid communication with each other within the reactor vessel, where the catalyst is a mixture of reduced metal oxides; and contacting the fuel and catalyst with the gaseous reagent within the reactor vessel at a reaction temperature to produce gaseous products, where the gaseous reagent contains at least CO2 or H2O, where the fuel comprises a carbonaceous source, and wherein the gaseous products are CO or syngas.
Claims19
A catalytic method for producing gaseous products from a fuel and a gaseous reagent comprising:
- providing a catalyst and the fuel to a reactor vessel such that the catalyst and the fuel are in fluid communication with each other within the reactor vessel, wherein the catalyst comprises reduced metal aluminate compounds, wherein the reduced metal aluminate compounds are selected from the group consisting of Cux—Alm—Op, Fey—Alm—Op, Fey—Mnz—Alm—Op, Cux—Fey—Alm—Op, Cux—Mnz—Alm—Op, Cux—Fey—Mnz—Alm—Op, and combinations thereof, wherein 5≥x>0, 5≥y>0, 5≥z>0, 5≥m>0, and 4≥p>0;
- and
- contacting the fuel and catalyst with the gaseous reagent supplied from an external source within the reactor vessel at a reaction temperature to produce gaseous products, wherein the gaseous reagent comprises CO2, wherein the fuel comprises a carbonaceous source, and wherein the gaseous products comprise CO.
A catalytic method for producing syngas products from a carbonaceous source and gaseous reagent comprising:
- providing the carbonaceous source and a catalyst to a reactor vessel, wherein the catalyst comprises reduced metal aluminate compounds selected from the group consisting of Cux—Alm—Op, Fey—Alm—Op, Fey—Mnz—Alm—Op, Cux—Fey—Alm—Op, Cux—Mnz—Alm—Op, Cux—Fey—Mnz—Alm—Op, and combinations thereof, wherein 5≥x>0, 5≥y>0, 5≥z>0, 5≥m>0, and 4≥p>0;
- and
- contacting the carbonaceous source and catalyst with a gaseous reagent to generate gaseous products where the gaseous reagent comprises CO2 supplied from an external source and a gaseous product that comprises a product stream of at least 25% by volume CO.
