Abstract
The effect of activating Co/Al2O3 catalyst by diluted CO or H2 on catalyst performance for FischerTropsch 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 of the catalyst in presence of CO and H2 individually was evaluated using TPR analyses. The data
reveal that CO activates Co/Al2O3 catalyst at a lower temperature than H2 and produces a catalyst
with higher rate for liquid product formation. It also leads to higher methane selectivity probably due
to some cobalt carbide formation.
