摘要: 分别以ZSM-5(MFI)分子筛、IM-5(IMF)分子筛以及IM-5经草酸处理得到的IM-3M分子筛为催化剂,考察其在葡萄糖转化制备5-羟甲基糠醛(HMF)反应中的催化性能,并通过X射线衍射、N2吸附-脱附、氨程序升温脱附和吡啶吸附红外光谱等手段对分子筛的物化性质进行表征。结果表明:IM-5与IM-3M分子筛的比表面积(分别为412.1m2/g与459.5 m2/g)均大于ZSM-5分子筛(371.9 m2/g);与IM-5分子筛相比,IM-3M分子筛的介孔更多,其总孔体积显著增加,达到0.62 cm3/g,传质性能明显增强,同时其酸强度有所降低,抑制了积炭的生成,在葡萄糖转化制备HMF的反应中展现出良好性能。在四氢呋喃与氯化钠-水溶液组成的反应体系中,以IM-3M为催化剂,170℃下反应60 min后葡萄糖转化率达95.0%,HMF选择性为59.2%。该催化剂在循环使用4次后,HMF选择性仍保持在50%以上,且反应后分子筛结构未发生明显变化,显示出良好的稳定性。

Abstract: This study investigates the catalytic performance of ZSM-5 (MFI), IM-5 (IMF), and oxalic acid-treated IM-3M zeolites in the conversion of glucose to 5-hydroxymethylfurfural (HMF). The physicochemical properties of the zeolites were systematically characterized by XRD, SEM,BET, NH3-TPD, and Py-FTIR. The results show that both IM-5 and IM-3M zeolites exhibit larger specific surface areas (412.1 m2/g and 459.5 m2/g, respectively) than ZSM-5 (371.9 m2/g). Moreover, the IM-3M sample obtained after oxalic acid treatment possesses more mesopores, leading to a significant increase in total pore volume (0.62 cm3/g), enhancing the diffusion of substrates and products. The reduction acid strength of IM-3M further suppressed coke formation, resulting in superior performance in the glucose-to-HMF conversion.Consequently, the IM-3M catalyst exhibited superior performance in a THF/NaCl-H2O biphasic system, achieving 95.0% glucose conversion with 59.2% HMF selectivity at 170 ℃ within 60 min. After four consecutive reaction cycles, the HMF selectivity remained above 50%, and the zeolite structure showed no significant changes, demonstrating excellent catalyst stability.
