[Display omitted] •The yield of furfural are affected by temperature, reaction time, additives and initial pressure.•Reaction pathways are clarified from dehydration, isomerization and 1, 2-enediol intermediate.•The kinetics of converting xylose and lignocellulose into furfural were reviewed.•The effects of homogeneous and heterogeneous catalysts on hydrothermal reactions were evaluated. Furfural is an important platform chemical, and the hydrothermal conversion of biomass to produce furfural is a research hotspot at present. The ideal carbohydrate for furfural production comes from biomass rich in hemicellulose. In this review, the latest progress of furfural production by biomass hydrolysis was summarized, and the influencing factors of furfural yield were analyzed in detail. In addition, the new catalysts and solvent system developed recently were also reviewed. Catalysts and solvent systems are classified. The synergistic effect of different catalysts and solvent systems on furfural production was elaborated. The reaction mechanism for the production of furfural from biomass was described in terms of kinetics and reaction pathways. However, among the numerous laboratory research results, it is necessary to further analyze its economy and explore the catalytics and solvent systems which are suitable for industrial production. This review has certain reference significance for the industrial production of furfural.
