Phosphorus-modified ordered mesoporous CoAlOx mixed oxides for product distribution during Fischer-Tropsch synthesis reaction |
초록 |
Fischer-Tropsch synthesis (FTS) is an alternative chemical process which can convert various carbon feedstocks into synthetic fuels via reforming process. A phosphorous-modified ordered mesoporous CoAlOx mixed oxides was prepared by using a hard-template of KIT-6 and a subsequent impregnation of phosphorous species with different contents. The phosphorous modification of mesoporous CoAlOx revealed a suppressed cobalt aluminate formation and less pronounced aggregation of cobalt particles as well. The suppressed aggregation of cobalt particles seems to be attributed to a localized presence of aluminum phosphate by forming a thermally stable metal–phosphorous oxo-species on mixed CoAlOx surfaces, which can significantly enhance the catalytic activity and structural stability of the phosphorous-modified ordered mesoporous CoAlOx under FTS reaction conditions. |
