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.
