Abstract: Furfural is a highly versatile and key derivative used in the manufacture of a wide range of important chemicals. However，it is also associated with low yield，energy-intensive and negative environment impact in conventional process for producing furfural. Current mainstream techniques (Quaker Oats，Agrifuran，Petrole-chimie，Escher Wyss and Rosenlew) for furfural production are reviewed；the mechanism and kinetics of hydrolysis of hemicelluloses into furfural are analyzed. The equipment up to date and alteration for furfural production are also discussed. Besides，new furfural manufacturing-processes are analyzed by optimizing solvent，catalyst，separation and heat-up. In order to minimize the impact of furfural production to environment，the research on new green catalyst and solvent system should be more emphasized.

Key words: furfural, technology, synthesis, catalyst, reaction solvent

摘要： 糠醛是一种应用广泛的化工原料，其现有生产工艺在产率、能耗及环境污染等方面存在较大问题。本文介绍了现有的主流生产工艺如Quaker Oats工艺，Agrifuran工艺，Petrole-chimie工艺，Escher Wyss工艺及Rosenlew工艺存在的不足，分析了半纤维素生成糠醛的机理及水解动力学研究、糠醛生产设备的更新改造。从溶剂体系、催化剂体系、分离方法、加热方式等多方面探讨发展新的糠醛生产工艺。提出今后的研究重点要放在开发绿色的溶剂及催化剂上，以期对生态环境的危害降至最低。
