Comparison of acid and alkali catalyzed ethylene glycol organosolv pretreatment for sugar production from bagasse

Weiqi Wei et al.

Summary: In this study, five acid or alkali catalyzed ethylene glycol (EG) organosolv pretreatments were proposed and compared for sugar production from bagasse. The results showed that EG/H2O-HCl pretreatment was more efficient for both hemicellulose and lignin remove, while EG/H2O-NaOH pretreatment was beneficial for lignin remove but weak for hemicellulose degradation. Both pretreatments have good capacity to reserve the cellulose in pretreated solids.

Victor Zhenquan Ong et al.

Summary: This study explored the use of ultrasound-assisted NaOH-aqueous DES pretreatment on oil palm frond to increase delignification and enhance enzymatic saccharification. Results showed that under the recommended ultrasonic pretreatment, lignin removal was significantly improved, leading to a high glucose yield during enzymatic saccharification. The use of NaOH-aqueous DES as an ultrasonic medium was proven to be an effective method for a novel one-pot, two-processes pretreatment system.

Facilitating enzymatic hydrolysis with a novel guaiacol-based deep eutectic solvent pretreatment

Chen Huang et al.

Summary: The study shows that the addition of trace AlCl3 during the enzymatic degradation process using DES can significantly enhance the degradation of hemicellulose and lignin, improving the enzymatic digestibility of pretreated plant fibers. Alkali washing is a feasible method to remove the precipitated lignin after degradation, which can significantly increase the enzymatic hydrolysis efficiency of the materials.

Structure-property-performance relationships of lactic acid-based deep eutectic solvents with different hydrogen bond acceptors for corn stover pretreatment

Xinquan Liang et al.

Summary: This study investigated the pretreatment of corn stover using lactic acid-based deep eutectic solvents with varying hydrogen bond acceptor structures. The results showed that DESs with short alkyl chain HBAs were more effective in removing lignin and xylan and promoting enzymatic digestion. Additionally, the hydrogen bond acidity of the DESs was found to have a strong positive relationship with pretreatment efficacy, providing insights into the design and selection of DESs for lignocellulose pretreatment.

High yield synthesis of hexitols and ethylene glycol through one-pot hydrolytic hydrogenation of cellulose

Akshay R. Mankar et al.

Summary: The catalytic valorization of biomass, particularly cellulose, has attracted significant attention globally. By using heteropolyacid/zirconia and Ru/C catalyst, a one-pot conversion of cellulose was achieved with high selectivity towards hexitols and ethylene glycol. Pre-treatment of cellulose with ball-milling showed improved catalytic performance, leading to almost complete conversion of cellulose and high yields of hexitols and ethylene glycol.
