Abstract
Described herein are catalysts and methods for converting waste biogas (e.g., a mixture of carbon dioxide and methane) into useful products. In some embodiments, the biogas is converted into a highly purified methane, that can be further processed to generate fuel products, including recycled natural gas (RNG) and liquid fuels. The described catalysts and methods may be advantageous over conventional methods, including by reducing catalyst costs, decreasing temperature requirements and/or providing higher purity products by reducing carbon dioxide and carbon monoxide in product streams.
Claims7
A catalyst system comprising:
- a substrate comprising a metal oxide;
- an atomically dispersed transition metal comprising Mo;
- wherein the atomically dispersed transition metal is dispersed in groupings less than or equal to 50 atoms;
- wherein said catalyst promotes the conversion of CO2 and H2 into CH4.
A catalyst system comprising:
- a substrate selected from the group consisting of TiO2 and Of CeO2;
- an atomically dispersed transition metal comprising Mo;
- wherein the atomically dispersed transition metal is dispersed in groupings less than or equal to 50 atoms;
- wherein said catalyst promotes the conversion of biogas comprising a mixture of CH4 and CO2 into a recycled natural gas comprising greater than 90% CH4, excluding produced water.
