Advances in production furfural via hydrolysis and application of furfural

As a value-added chemical product derived from renewable biomass, the furfural has many promising applications. In this paper, recent advances in the furfural production from biomass via hydrolysis were summarized, and the important derivatives of furfural and their applications were discussed. Based on the mechanical analysis of hemicellulose hydrolysis reaction and xylose dehydration reaction, the production advances of furfural via hydrolysis were discussed from the aspects of feedstock, solvent system, catalyst, and separation process. Furthermore, the shortcomings and possible solutions of the current furfural production method were proposed. In addition, the synthesis of high value chemicals via the hydrogenation, amination, oxidation, acetal or polymerization of furfural was summarized. In order to realize the green and efficient production and application of furfural, the reaction system with low cost, low energy consumption, low pollution, and high efficiency should be designed. At the same time, it’s very important to develop an economic and environmentally-friendly method to achieve the complete utilization of furfural-derived products.
