CO<sub>2</sub> Methanation on Fe Catalysts Using Different Structural Concepts
Johann Kirchner, Christian Zambrzycki, Sven Kureti, Robert Güttel
Abstract
Abstract The hydrogenation of carbon dioxide towards methane and water is evaluated on different types of iron catalysts. The catalysts refer to different structural concepts implying a bare iron oxide, a silica‐supported and a core‐shell system. Highest CO 2 conversion of about 20 % is achieved with the bulk catalysts and the supported material. However, although revealing reduced CH 4 formation rate, the core‐shell catalyst exhibits pronounced resistance against coke formation as well as thermal sintering and particle attrition upon syngas reaction.
