Highlights
• Recycle of [amim]Cl and [bmim]OAc for the pretreatment and hydrolysis of eucalyptus.
• The hydrolysis yields of eucalyptus were improved by recycled ILs pretreatment.
• Cellulose digestibility slightly decreased with the increased reuse number of ILs.
• No appreciable changes in structure and thermal stability of recycled [amim]Cl.
• The anionic structure of 4th recycled [bmim]OAc was destroyed or replaced.
论文摘要 Abstract
It is urgent to develop recycled ionic liquids (ILs) as green solvents for sustainable biomass pretreatment. The goal of this study is to explore the availability and performance of reusing 1-allyl-3-methylimidazolium chloride ([amim]Cl) and 1-butyl-3-methylimidazolium acetate ([bmim]OAc) for pretreatment, structural evolution, and enzymatic hydrolysis of eucalyptus. Cellulose enzymatic digestibility slightly decreased with the increased number of pretreatment recycles. The hydrolysis efficiencies of eucalyptus pretreated via 4th recycled ILs were 54.3% for [amim]Cl and 72.8% for [bmim]OAc, which were 5.0 and 6.7-folds higher than that of untreated eucalyptus. Deteriorations of ILs were observed by the relatively lower sugar conversion and lignin removal from eucalyptus after 4th reuse. No appreciable changes in fundamental framework and thermal stability of [amim]Cl were observed even after successive pretreatments, whereas the anionic structure of [bmim]OAc was destroyed or replaced. This study suggested that the biomass pretreatment with recycled ILs was a potential alternative for low-cost biorefinery.
