Background and Aims.
The complex structure of the lignocelluloses is the main obstacle in the conversion of lignocellulosic biomass into valuable products.
Ionic liquids provide the opportunities for their efficient pretreatment for biomass.
Therefore, in this work, pretreatment of corn stalk was carried out in ultrasonic-assisted ionic liquid including 1-butyl-3-methylimidazolium chloride [BMIM]Cl, 1-H-3-methylimidazolium chloride [HMIM]Cl, and 1-(1-propylsulfonic)-3-imidazolium chloride [HSO3-pMIM]Cl at 70°C for 2 h.
We compared the pretreatments by ionic liquid with and without the addition of deionized water.
Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM) were employed to analyze the chemical characteristics of regenerated cellulose-rich materials.
Results.
[HMIM]Cl and [HSO3-pMIM]Cl were effective in lignin extraction to obtain cellulose-rich materials.
FTIR analysis and SEM analysis indicated the effective lignin removal and the reduced crystallinity of cellulose-rich materials.
Enzymatic hydrolysis of cellulose-rich materials was performed efficiently.
High yields of reducing sugar and glucose were obtained when the corn stalk was pretreated by [HMIM]Cl and [HSO3-pMIM]Cl.
Conclusions.
Ionic liquids provided the ideal environment for lignin extraction and enzymatic hydrolysis of corn stalk and [HMIM]Cl and [HSO3-pMIM]Cl proved the most efficient ionic liquids.
This simple and environmentally acceptable method has a great potential for the preparation of bioethanol for industrial production.
