Abstract
The present invention describes a process and catalysts for the conversion of a light hydrocarbon and carbon dioxide input stream into high quality syngas with the subsequent conversion of the syngas into fuels or chemicals. In one aspect, the present invention provides an efficient, solid solution catalyst for the production of a carbon containing gas from carbon dioxide and light hydrocarbons. The catalyst comprises a single transition metal, and the transition metal is nickel.
Claims12
A solid solution catalyst for the production of high quality syngas from carbon dioxide and light hydrocarbons, wherein the catalyst comprises a single transition metal, and wherein the transition metal is nickel.
2-31. (canceled)
A solid-state catalyst formulation, wherein the catalyst formulation is not coated on a substrate, and wherein the catalyst formulation is capable of producing syngas with a pre-selected ratio of H2/CO, and wherein the H2/CO ratio is capable of being varied based on the production process used to produce the syngas.
The solid-state catalyst formulation according to claim 6, wherein the nickel concentration in the catalyst formulation ranges from five weight percent to 20 weight percent.
The solid-state catalyst formulation according to claim 9, wherein the production process is selected from a group of production processes consisting of dry reforming, combination dry/steam reforming and tri-reforming conditions, and wherein the catalyst formulation is capable of producing syngas with a H2/CO ratio ranging from 1.5 to 2.5 or from 0.7 to 1.0, and wherein the catalyst formulation is stable up to 1,100° C., and wherein the catalyst formulation does not include a precious metal, and wherein the catalyst formulation is capable of producing syngas from light hydrocarbons with a conversion efficiency ranging from 90 percent to 100 percent.
