The utilization of renewable biomass resources play an important role in solving the energy crisis and reducing environmental pollution. Along this background, the production of furan-based chemicals from lignocellulose becomes one of the research focuses in biorefinery. Furfural is the key furan-based building block, which is manufactured from hemicellulose fraction directly, and offers a promising, rich platform for lignocellulosic biofuels and value-added chemicals. So it is of great practical significance to develop green technologies for the production of furfural and the conversion of furfural to primary furan-based chemicals. In this review, the formation routes and catalytic conversion of hemicellulose into furfural were summarized with special attentions on the heterogeneous acid-catalysts for the production of furfural in the liquid phase, including zeolites, metal oxides, ion-exchange resins, clays and carbon materials. The formation routes and technologies starting from furfural to various furan-based chemicals, including furfuryl alcohol, tetrahydrofurfuryl alcohol, 2-methylfuran, 2-methyltetrahydrofuran, furan, tetrahydrofuran, were reviewed.%生物质资源的开发利用是解决我国能源、资源与环境问题的重要途径之一.木质纤维作为生物质的主要组分,通过对其转化制备呋喃化学品是当前生物炼制领域研究的热点.糠醛是以半纤维素为直接原料的重要呋喃基平台化合物,开发其绿色制备工艺技术并大力发展高值糠醛下游产品,具有重要的现实意义.本文从催化转化角度出发,对糠醛形成的路线、近年来糠醛制备技术(水解技术和热解技术)及其重要呋喃基下游化学品的研究进展进行综述,重点介绍了非均相酸,包括分子筛、金属氧化物、离子交换树脂、黏土等催化的水解技术,以及糠醇、2-甲基呋喃、2-甲基四氢呋喃、呋喃和四氢呋喃等呋喃基衍生物的制备路线及方法,以期为绿色糠醛制备技术的建立及高值糠醛下游呋喃基化学品研发提供思路和参考.
