Abstract
By using different catalyst pretreatments, silica supported cobalt catalysts were activated to produce either hcp or fcc cobalt metal particles, as verified by XRD. H2-TPR and pulse re-oxidation experiments show a higher dispersion of cobalt for the catalyst containing the hcp metallic phase compared to the fcc phase. Cobalt containing hcp metallic phase has shown higher CO conversion on a catalyst weight basis and less methane selectivity compared to fcc containing catalysts under similar reaction conditions. Both hcp and fcc phases of cobalt are stable during the Fischer-Tropsch (FT) synthesis.
