Abstract: Lignocellulosic biomass provides alternative and renewable energy resources for sustainable production of organic fuels and chemicals. The deconstruction of lignocellulosic biomass is very difficult due to its complex, intricate and rigid structure formed by several covalent and non-covalent interactions. However, the ionic liquid technology on biomass processing is recently gaining importance over the other conventional methods due to the unique properties of ILs. This review focuses on the recent studies on biomass dissolution in several ILs for the fractionation and recovery of lignocellulosic components such as cellulose, hemicelluloses and lignin. The review further considers the influence of several crucial parameters that governs the dissolution process. This study also focuses on the role of membrane technology for separation and purification of lignin. As ionic liquids are very expensive therefore its recovery and reuse are necessary, and this study also emphasizes the use of nanofiltration for recovery of ILs.
