Synthesis and Characterization of Fe-Co Catalyst Prepared via Reverse Microemulsion Method

This paper reports the characterization of bimetallic catalyst systems comprising cobalt and iron on CNTs support prepared via reverse microemulsion method. The properties of the bimetallic catalyst were characterized using TEM, FESEM and N2 adsorption. Based on TEM analyses, the calculated average particle sizes ranged from 4.6 nm to 5.2 nm for the various catalyst compositions. The performance of the Co-based catalyst in a Fischer-Tropsch reaction was evaluated in a fixed-bed reactor at 220oC, 1 atm and H2/CO v/v ratio of 2:1 . Amongst the catalysts tested, the 90Co10Fe/CNTs resulted in the highest CO conversion of 14.1% whereas the 100Co/CNTs resulted in the highest C5+ hydrocarbon selectivity.
