Abstract: As an important organic chemical raw material，furfural can be obtained from biomass conversion. It is a renewable and green chemical product，and widely used in chemical and pharmaceutical industries. The research on the production of furfural from biomass through hydrolysis and pyrolysis are summarized. One-step furfural production process，and two-step furfural production process as well as the progress in catalyst development in each processe are reviewed. The technology in one-step furfural production process from initial single - pot cooking to multiple pots in series and from technical process of batch reactor to a continuous reactor is discussed. Two-step method is more common and makes a significant breakthrough in new catalyst development，furfural extraction，and furfural yield. The affecting factors，procedure mechanism，as well as the advantages and disadvantages in hydrolysis and pyrolysis are discussed. The yield of furfural is also compared regarding the processing of biomass material. Overall，this review attempts to highlight the scope of further developments in the production of furfural，key factors in the development of furfural are pointed out.

摘要： 糠醛是目前只能由生物质转化而得到的重要的有机化工原料，是一种可再生、绿色的化工产品，被广泛应用于化工、医药等领域。本文归纳了生物质水解液化及高温分解制备糠醛研究中的关键问题，综述了生物质水解液化一步法、两步法转化制糠醛的催化剂发展及两种工艺的研究进展。一步法生产工艺及技术从最初的单锅蒸煮，发展到多锅串联以及连续生产工艺。两步法研究较为普遍，在新型催化剂、糠醛提取方式、糠醛收率方面都有很大突破。讨论了水解液化与高温分解过程的主要影响因素、机理以及各自的优缺点，从生物质原料处理的工序上比较糠醛的收率。并在此基础上，对生物质转化制糠醛的研究前景进行了展望，指出影响其发展的关键因素在于催化剂的开发，开发出环境友好、经济有效的催化剂是重中之重。
