| Popis: | Novel Fe���based core���shell catalysts are identified as promising CO2 hydrogenation catalysts. They reveal significantly reduced coke deposition (up to 300 times) and high thermal stability as compared to conventional impregnated and bulk Fe catalysts. 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 CO2 conversion of about 20 % is achieved with the bulk catalysts and the supported material. However, although revealing reduced CH4 formation rate, the core���shell catalyst exhibits pronounced resistance against coke formation as well as thermal sintering and particle attrition upon syngas reaction. publishedVersion |
