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.%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.
