英文摘要Ball milling pretreatment was found to be an efficient method to promote the catalytic conversion of lignocellulosic biomass to ethylene glycol (eg). after 3-6 h ball milling of miscanthus at 450 rpm, the eg yield reached about 52%, which is comparable to the result of pure cellulose conversion. the reasons of the promotion effect were investigated by characterizing the structure of biomass and the reaction residuals with x-ray diffraction, scanning electron microscopy, particle size distribution analyzer, contact angle measurement, thermogravimetric analysis-differential scanning calorimetry, and fourier-transform infrared spectroscopy. the mild ball milling liberated (hemi)cellulose from the compact plant tissues without affecting the crystallinity of cellulose. it reduced the size of biomass to 30 mu m and improved the accessibility of (hemi)cellulose, leading to a hydrophilic surface and high energy state of biomass for catalytic conversion. during the catalytic conversion, the mass transfer between sugar intermediates and heterogeneous hydrogenation catalysts were improved. correspondingly, the self-reaction of sugar intermediates, and the reactions between sugar intermediates and lignin fractions were suppressed, resulting in the high eg yield.
