The selectivity for gasoline fuels (C5-C11) selectivity over the Fe + ZSM5(33) catalyst is as high as 65.1 wt%, which is greater than that of traditional outstanding than the traditionally zeolite-supported and physically mixed bifunctional catalysts. The enhanced catalytic performance can be attributed to the weak acid content governing the catalytic cracking. ZSM5 zeolite with a suitable weak acid content and desorption temperature can facilitate the cracking of C12+ hydrocarbons, thereby facilitating the C5-C11 selectivity and inhibiting the deactivation of active sites resulting from the aggregation of C12+ hydrocarbons. Fe + ZSM5(27) with an suitable weak acid content provides a higher CO conversion of 93.6% combined with an excellent C5-C11 selectivity of 62.7 wt%.

The synthesized catalysts were systematically characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), N2 adsorption–desorption isotherm, temperature-programmed desorption of NH3 and CO2 (NH3/CO2-TPD), temperature-programmed reduction of H2 (H2-TPR), and X-ray photoelectron spectroscopy (XPS).
