Abstract
Fischer-tropsch catalysts with high activity and selectivity for olefins were produced using mordenite type SiO2/Al2O3= 12, 20, 28, 62 zeolite supported iron carbonyl compounds and were characterized by X-ray powder diffraction. The adsorptionof volatile Fe(CO)5 on the support surface was carried out under vacuum at room temperature. Reduction les were monitored by vibrating sample magnetometer (VSM). The magnetic saturation time was observed to increase with increasing the Al2O3 content of catalyst system indicating an increasing interaction between iron and alumina. The activity and selectivity of different iron deposited mordenite sample were investigated during Fischer-Tropsch synthesis of hydrocarbons with H2/CO=3 in the temperature range of 400-500 °C using a microreactor system. The results correlated with the acidic properties of surface and/or with metallic state of active iron particles of the catalyst.
