| 제목 | Direct CO2 conversion to liquid fuels and lube base oil using cobalt-based catalyst |
| 초록 | Dueto the high methane selectivity, CO2 direct hydrogenation tolong-chain hydrocarbon over cobalt-based catalysts is challenging. We produce a high C5+ yield of 21.1% with low CO selectivityusing a Na- and Mn- promoted, core-shell Co@CoOx/Co2Ccatalyst. Catalyst activities such as C5+ selectivity and CO2conversion are well retained over 1425h. As the reaction progressed, C21+selectivity has increased to 14.9%. Oxygen-vacant Co3O4on the outer shell is an active site for the plausible reverse-water-gasshift reaction (RWGS). Mn promoter facilitated the core-shell structure andreduced the methanation by suppressing direct contact between CO2and metallic cobalt in the core. |
