| 英文摘要 | sulfonated hierarchical h-usy zeolite was prepared and characterized by x-ray diffraction, n-2 physisorption, fourier transform infrared spectroscopy, inductively coupled plasma atomic emission spectroscopy, temperature-programmed desorption of ammonia, and acid-base titration. it was proved that sulfonic group was successfully anchored onto the hierarchical h-usy zeolite. the acidity of the hierarchical h-usy was remarkably improved. sulfonated hierarchical h-usy zeolite was efficient for the hydrolysis of hemicellulose and cellulose. the yield of trs for hydrolysis of hemicellulose reached 78.0% at 140 c for 9 h. for hydrolysis of alpha-cellulose, 60.8% conversion with 22.4% yield of glucose was obtained. even for microcrystalline cellulose, 43.7% conversion with 15.1% yield of glucose can be obtained. these results are much higher than those obtained over hierarchical h-usy zeolite, indicating that both the acidity and the pore structure determine the activity of zeolite as catalyst in the hydrolysis of biomass.
