Abstract
The ionic liquids (ILs) are recognized as the potential solvents for the pretreatment of lignocellulosic materials before biomass conversion. However, little knowledge of how the cell wall of biomass responds to the IL locally and dynamically during the pretreatment is available. In the current work, the process of IL pretreatment of poplar using 1-ethyl-3-methylimidazolium acetate ([C2 mim][OAc]) was real-time monitored on a cellular level by employing confocal Raman microscopy. The results showed that the biomass dissolution during the IL pretreatment can be clearly divided into two stages: (1) slow penetration of IL, and (2) rapid dissolution of lignin and carbohydrates. In this case, the onset of the dissolution of these compositions occurred only after the cell wall of biomass swelled to a certain extent. Because the first stage was a slow process which determined the process reaction rate, it can be deduced that enhancing the penetration capacity of IL was crucial for improving the pretreatment efficiency. Based on the obtained results, a model was proposed to better understand how the plant cell wall responds to the IL before, during, and after pretreatment.
