| 英文摘要 | 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). |
