摘要:

糠醛是连接生物原料和生物炼制工业的桥梁。糠醛在水介质中的还原性转化是制备各种精细化学品的重要途径, 经多相催化剂催化可以得到大量的下游产品, 如(四氢)糠醇、2-甲基(四氢)呋喃、内酯、乙酰丙酸盐、环戊酮、环戊醇等。催化剂的活性主要取决于金属及载体的性质, 以及温度、时间、溶剂和压力等反应条件。本文针对不同的非贵金属(Cu、Ni和Co)和贵金属(Pd、Ru、Pt和Au)基催化剂对糠醛加氢制备环戊酮和环戊醇的研究进展进行了综述, Ru、Pd、Au和Cu基催化剂较其他催化剂有更高的选择性, Cu-Ni双金属催化剂具有优异的催化活性和选择性, 但稳定性有待提高。对金属表面发生氢化反应的机理进行了探讨, 结果表明: 水介质和较弱的路易斯酸性位点在环重排的反应中起关键作用, 同时提出了糠醛在水介质中的加氢反应的未来研究方向。

Abstract:

Furfural is the bridge connecting raw biomass to the biorefinery industry. The reductive transformations of furfural in aqueous medium is an important way to prepare a wide variety of fine chemicals. Plenty of downstream products can be obtained by heterogeneous catalyst, such as(tetrahydro) furfuryl alcohol, 2-methyl(tetrahydro) furan, lactone, levulinate, cyclopentanone, cyclopentanol, and so on. The activity of catalyst mainly depends on the properties of metal and support, as well as reaction conditions, such as temperature, time, solvent, and pressure and so on. The research progress of furfural hydrogenation for preparing cyclopentanone and cyclopentanol using different non-noble metal(Cu, Ni, and Co) and precious metals(Pd, Ru, Pt, and Au) based catalyst were summarized. It was found that Ru, Pd, Au, and Cu-based catalysts have higher selectivity than other catalysts, and Cu-Ni bimetallic catalysts have excellent catalytic activity and selectivity, while their stability needs to be improved. The mechanism of the hydrogenation reaction on the metal surface was discussed, and the results showed that the aqueous medium and weaker Lewis acid sites play an important role in the reaction of ring rearrangement. Meanwhile, the future research direction of the hydrogenation reaction of furfural in aqueous medium is proposed.
