Fe-promoted Co/AC catalysts (15CoxFe/AC) were synthesized by co-impregnation method and studied using CO hydrogenation reaction, N2 adsorption, ex-situ/in-situ XRD, H2-TPR, CO chemisorption and HRTEM. The results showed that the catalytic performance was improved by adding Fe into the 15Co/AC catalyst. Appropriate amount of Fe improved metal dispersion and CO uptake, thus leading to the enhancement...
An alternative CaO-promoted Co/AC catalysts with high selectivity of C1–C16 alcohols were synthesized and systematically studied. The catalysts were characterized by means of N2-physisorption, XRD, H2-TPR, CO-chemisorption and HRTEM. Then the activated catalysts were used in the CO hydrogenation reaction for the alcohols synthesis. Reaction results showed that CaO promoter improved the yield of C1...
The influence of Al2O3 promoter on a performance of C1–C14 α-alcohols direct synthesis from syngas over activated carbon (AC) supported cobalt catalysts (Co/AC catalysts) was investigated using CO hydrogenation evaluation, XRD, HRTEM, H2-TPR, pulsed CO chemisorption, H2-TPD and N2 physisorption techniques. The results obtained showed that the addition of Al2O3 increased significantly the Co component...
