“…The ether‐oxygen bond in hemicellulose is disconnected by the action of hydrogen protons from the CS−SO 3 H. Then it was hydrolyzed to form monosaccharides such as xylose. The hydrogen proton from the CS−SO 3 H protonates the hydroxyl group in xylose to lose three water molecules to form furfural [45] . Monosaccharides is easily consumed by side reactions with other components.…”

“…The hydrogen proton from the CSÀ SO 3 H protonates the hydroxyl group in xylose to lose three water molecules to form furfural. [45] Monosaccharides is easily consumed by side reactions with other components. Based on the above process analysis, it can be found that several reasons contribute to the relatively low yield of furfural from corn cob.…”

Carbon‐based solid acid catalysts (CS−SO3H) were prepared by one‐pot carbonization‐sulfonation method with concentrated sulfuric acid using cotton as raw material, which was used to transformation of xylose and corn cob to furfural. The catalyst preparation conditions were optimized to be that the cotton mass/sulfuric acid volume ratio is 1 : 20 (g/mL), and the reaction is carried out at 160 °C for 10 h. The morphology, functional groups and surface chemical state were investigated. The yield of furfural can reach 87.3 % from xylose under the optimal reaction condition of 0.1 g xylose, 0.05 g catalyst, 180 °C for 90 min in 5.0 mL γ‐valerolactone‐water solvent. The yield of furfural can reach 63.2 % by the direct one‐pot conversion of corn cob over the CS−SO3H under the optimal reaction condition of 0.1 g corn cob, 0.1 g catalyst, 190 °C for 90 min in 5.0 mL γ‐valerolactone‐water solvent. The catalytic activity gradually declined when it was cycled for four times. The reason was determined to be the partial shedding of the sulfonic acid groups grafted on the catalyst during the reaction and insoluble humus accumulated on the catalyst surface. After regeneration, the catalytic activity can be restored.

“…As shown in Figure 1 , lignocellulose is mainly composed of cellulose (40–45%), hemicellulose (20–40%), and lignin (10–25%), which are tightly bound together to form the skeletal framework of plant. The three-dimensional network structure shows that cellulose and hemicellulose are mainly connected by hydrogen bonds, and lignin and hemicellulose are also linked with chemical bonds, such as hydrogen bonds, ionic bonds, covalent bonds, and hydrophobic interactions [ 23 ].…”

The stubborn and complex structure of lignocellulose hinders the valorization of each component of cellulose, hemicellulose, and lignin in the biorefinery industries. Therefore, efficient pretreatment is an essential and prerequisite step for lignocellulose biorefinery. Recently, a considerable number of studies have focused on peroxyacetic acid (PAA) pretreatment in lignocellulose fractionation and some breakthroughs have been achieved in recent decades. In this article, we aim to highlight the challenges of PAA pretreatment and propose a roadmap towards lignocellulose fractionation by PAA for future research. As a novel promising pretreatment method towards lignocellulosic fractionation, PAA is a strong oxidizing agent that can selectively remove lignin and hemicellulose from lignocellulose, retaining intact cellulose for downstream upgrading. PAA in lignocellulose pretreatment can be divided into commercial PAA, chemical activation PAA, and enzymatic in-situ generation of PAA. Each PAA for lignocellulose fractionation shows its own advantages and disadvantages. To meet the theme of green chemistry, enzymatic in-situ generation of PAA has aroused a great deal of enthusiasm in lignocellulose fractionation. Furthermore, mass balance and techno-economic analyses are discussed in order to evaluate the feasibility of PAA pretreatment in lignocellulose fractionation. Ultimately, some perspectives and opportunities are proposed to address the existing limitations in PAA pretreatment towards biomass biorefinery valorization. In summary, from the views of green chemistry, enzymatic in-situ generation of PAA will become a cutting-edge topic research in the lignocellulose fractionation in future.

“…The valorization of hemicellulose fraction usually involves three steps: (i) the deconstruction of the hemicellulose−cellulose− lignin network to extract hemicellulose, (ii) the hydrolysis of hemicellulose to pentose, and (iii) the pentose conversion. 9 In the present work, the catalytic hydrogenation of hemicellulose hydrolysates from wheat bran is studied. As a low-cost and abundantly produced byproduct of the milling industry, cereal bran can also be used as a raw material in a cereal-based biorefinery.…”

Monometallic Ru/MCM48 and Zr/MCM48 and bimetallic Ru/Zr-MCM48 and Zr/Ru-MCM48 catalysts have been synthesized and tested in the hydrogenation of wheat bran hydrolysates. Catalysts have been characterized by XRD, SAXS, TPR, TPD-NH3, TEM, and N2 adsorption/desorption at 77 K. The hemicellulose fraction has been extracted, hydrolyzed, and purified before the hydrogenation reaction. The purification step mainly consists of the extraction of the sugars in an organic phase and a back-extraction in an acid-aqueous solution. Ru/Zr-MCM48 catalyst exhibited the highest conversions of sugars in the hydrogenation of the purified wheat bran hydrolysate (PWBH), practically unchanged after 5 reaction cycles. Sugar alcohol yields were 73.2% in pentitols and 65.9% in sorbitol. The incorporation of the tetragonal ZrO2 to the MCM48 support has led to a more active and stable catalyst for the hydrogenation of PWBH. Results have shown that this incorporation must be done before the deposition of the Ru(0) phase.
