The production of light olefins, are the key components in petrochemical industries, is possible via different technologies. The Fischer–Tropsch (FT) process as a proper method, aims to convert syngas to light olefins with high selectivity over a proper catalyst, reduce methane formation, and avoid the production of excess CO2. In this research, Fe/Co/ γ-Al2O3 and Fe/Co/ γ-Al2O3+H-ZSM-5 catalysts synthesized by the IWI procedure to research the effects of H-ZSM-5 zeolite addition on the catalytic activity and selectivity in a fixed-bed reactor were Characterization of catalysts was carried out usingby XRD, BET, . Operation of synthetic catalysts conducted in a temperature range of 260–280-300 ˚C, pressure range of 1–5-10 bar, feed ratio of 1.3 and a space velocity of 2 . By adding 20% of zeolite H-ZSM-5 to gamma-alumina support, the production of light olefins increased from 7.86% to 8.49%, the percentage of carbon monoxide increased from 23.76% to 26.42% and also The selectivity of decreased from 89.43% to 41.28%.
