Fischer-Tropsch Synthesis over Unpromoted Co/ɣ-Al2O3 Catalyst: Effect of Activation with CO Compared to H2 on Catalyst Performance
The effect of activating Co/Al2O3 catalyst by diluted CO or H2 on catalyst performance for Fischer-Tropsch reaction was investigated. The catalyst was prepared by incipient wetness impregnation of the support and characterized using BET N2 physisorption, SEM, and XRD analyses. The reduction behavior...
