摘要: In the present article, effects of Fe/Cu/K catalyst particle size have been considered on CO and CO2 hydrogenation reactions. The variation crucial factors such as surface area basicity, reduction, carburization catalytic behavior precipitated catalysts were scrutinized. Various tensions hematite nanoparticles produced by homogeneous precipitation in alcohol/water mixed solvents. CO2-TPD results revealed that basicity potassium promoted iron is increased with lower size. Increasing K-basic sites at attributed to their higher areas. Moreover, CO-TPR proved elevation leads increasing dissociative adsorption considerably. Shifting oxygen removal pattern temperature consequence faster nucleation FeCx crystallites oxides. also indicate reaction can occurred two distinct direct indirect routs via Fischer-Tropsch mechanism.
