co-precipitation, impregnation and sol-gel techniques were employed to examine effect of temperature on light olefins selectivity using Fischer-Tropsch Synthesis (FTS). The results illustrated that Fe/Mn/Al2O3 catalyst which is prepared by the impregnation method had less methane selectivity and more selectivity to light olefins which had the highest chain growth probability based on heavier hydrocarbon formation but it had more CO2 selectivity than the other techniques.
