Performance of Ce-incorporated KIT-6 supported cobalt catalysts for fischer-Tropsch synthesis

Performance of Ce-incorporated KIT-6 supported cobalt catalysts for fischer-Tropsch synthesis

A series of Ce-incorporated structure of cubic large mesoporous molecular sieves, KIT-6, with different Ce contents were synthesized by a direct hydrothermal process. A sample of Ce-loaded KIT-6 material was synthesised by incipent wetness impregnation. Similarly, catalysts with 15 wt.% Co loading o...
