摘要：Thermochemical conversion of lignocellulosic biomass into value-added chemicals has attracted great interest worldwide. Herein, we report an effective and facile process to transform bamboo into 5-hydroxymethylfurfural (5-HMF), furfural (FF) and levulinic acid (LA) using metal chlorides as catalysts. The effects of the reaction parameters, such as the reaction time, temperature, initial pressure and catalyst loading on the bamboo conversion and product yields were investigated. Notably, the optimum reaction conditions were heating 200 °C for 2 h using 0.75 g of SnCl4 as catalyst in a 90.0 wt% aqueous sulfolane solution, where the conversion of bamboo was 90.0 wt% forming 41.2 mol% of 5-HMF, 20.1 mol% of FF and 24.6 mol% of LA. The synergistic effect of [Sn(OH)3(aq)]+ and cation polarization has an important role in the outstanding efficiency and specificity of our selective liquefaction system. Moreover, the water/sulfolane system displays excellent performance for maintaining the Lewis acid active sites in [Sn(OH)3(aq)]+. In the process, sulfolane regulates the hydrolysis of SnCl4 to provide an effective Lewis acid strength. This study sheds light on the remarkable potential of the process for future industrial application. ? 2020 Energy Institute
