| Abstract | Bi-functional catalysts were prepared using hybrid supports, mesoporous SiO2(SG) and microporous HP zeolites with different Si/Al ratios of 25, 60 and 80 for direct jet fuel-range hydrocarbon synthesis (C-8-C-18). The textual and structural properties of the catalysts were studied by Fourier transform infrared (FTIR), X-ray diffraction(XRD), H-2-temperature-programmed desorption(H-2-TPR) and N-2 physisorption. The results showed that catalysts supported on tailor-made SiO2 and H beta hybrid maintained both meso- and micro-pores with acid centers. With the decrease of Si/Al ratio, the bands corresponding to the characteristic adsorptions of Co/SG/H beta catalysts shifted to the lower wave numbers, which accompanied by increased acidity. SiO2 decreased the acidity of H beta and the interaction between Co and support, resulting in high Co dispersion, reduction and CO conversion for Co/SG/H beta. The microporous structure and acidity of H beta accelerated the hydrocracking/hydroisomerizaion reaction, which contributed to the high selectivity to jet fuel-range isoparaffins. The increased BET surface area and microporous volume with moderate acidity of Co/SG/H beta(80) were essential for its high CO conversion (95.7%) and selectivity to jet fuel-range hydrocarbons (42.3%, including 27.6% of isoparaffins). |
