ENHANCED CO2 ADSORPTION USING TRANSITION METALS SUCH AS RU AND NI AND THEIR OXIDES IN COMBINATION WITH ALKALINE METAL OXIDES AND HIGH SURFACE AREA CARRIERS

Document Type and Number:

WIPO Patent Application WO/2022/256361

Kind Code:

A3

Abstract:

A dual function material is provided that captures carbon dioxide from ambient air, i.e., direct air capture, and converts the CO2 to a desired product such as methane. The material includes a high surface area carrier such as AI2O3 upon which catalysts and alkaline adsorbents are positioned proximate each other. In the presence of reactive gas such as hydrogen, the catalysts reduce the adjacent adsorbents to generate additional active sites and enhance the amount of CO2 captured by the material. Once the material becomes saturated with CO2, hydrogen is reintroduced to reduce the catalyst, such as ruthenium, at which time the adsorbed CO2 can migrate from the adsorbent to the catalyst for catalytic conversion to methane. The materials can be employed in isothermal, cyclic reactor systems where target species are bound and then desorbed to reactivate the material, e.g., bind more target species for desorption and/or conversion to additional product.
