摘      要：Different Fe catalysts have been synthesized both conventionally and by ultrasonic impregnation with different promoters (K, Mn) to obtain light olefins with high selectivity from the synthesis gas, avoiding excess CO2 production and reducing CH4 formation. The performance of proposed catalysts was analyzed and compared in terms of CO conversion, saturated hydrocarbons C2-C4 selectivity, unsaturated hydrocarbons C2-C4 selectivity, and unsaturated hydrocarbons C2-C4 yield, while varying the temperature in the range 250 – 350 °C. The influence of CO:H2 molar ratio (1:1 and 1:2) was also observed. © 2022, Politechnica University of Bucharest. All rights reserved.
