In this work, p-hydroxybenzenesulfonic acid-formaldehyde resin acid catalyst (MSPFR), was synthesized by a hydrothermal method, and employed for the furfural production from raw corn stover. Scanning electron microscopy (SEM), transmission electron microscopy (TEM), N adsorption-desorption, elemental analysis (EA), thermogravimetric analysis (TGA), and Fourier transform infrared spectroscopy (FT-IR) were used to characterize the MSPFR. The effects of reaction time, temperature, solvents and corn stover loading were investigated. The MSPFR presented high catalytic activity for the formation of furfural from corn stover. When the MSPFR/corn stover mass loading ratio was 0.5, a higher furfural yield of 43.4% could be achieved at 190 °C in 100 min with 30.7% 5-hydroxymethylfurfural (HMF) yield. Additionally, quite importantly, the recyclability of the MSPFR for xylose dehydration is good, and for the conversion of corn stover was reasonable.
在这项工作中，通过水热法合成了对羟基苯磺酸-甲醛树脂酸催化剂（MSPFR），并将其用于从原料玉米秸秆中生产糠醛。采用扫描电子显微镜（SEM）、透射电子显微镜（TEM）、N 吸附-脱附、元素分析（EA）、热重分析（TGA）和傅里叶变换红外光谱（FT-IR）对 MSPFR 进行了表征。考察了反应时间、温度、溶剂和玉米秸秆负载量的影响。MSPFR 对玉米秸秆生成糠醛具有较高的催化活性。当 MSPFR/玉米秸秆质量负载比为 0.5 时，在 190°C 下反应 100 分钟，MSPFR 用量为 0.5，30.7%的 5-羟甲基糠醛（HMF）收率可得到 43.4%的糠醛收率。此外，非常重要的是，MSPFR 用于木糖脱水的可回收性良好，用于玉米秸秆的转化率合理。
