“…Biomass is one of the most attractive alternatives to fossil resources for producing fuels and many other important chemicals and has therefore been studied intensely in recent years. − In countries with large forested areas, such as Japan, lignocellulosic biomass is expected to be an abundant natural resource; thus, its utilization has gradually increased. Its potential as an alternative to fossil resources is not the only reason why the utilization of biomass is important.…”

5-Hydroxymethylfurfural (HMF) was effectively produced from monosaccharides in a microreactor. A biphasic reaction system was employed to achieve the immediate extraction of produced HMF and suppress the overreaction. A microreactor was utilized to ensure that the reaction occurred under segmented flow to enhance the extraction efficiency. Through many attempts using phosphate buffer saline (PBS) as the reaction phase and 2-sec-butyl phenol (2BP) as the extraction phase, the favorable conditions were determined. By using PBS with pH of 2.0 and 2BP at a volume ratio of 3 to PBS, 80.9 mol % of fructose and 75.7 mol % of glucose were converted into HMF, respectively, at 180 °C. By comparing the results obtained through monophasic reactions, it was confirmed that the biphasic system successfully suppressed both the overreaction and the byproducts. The system employed only a simple experimental apparatus and the acid solution and organic solvent reagents without any complex expensive catalyst.

“…Lignocellulose, including cellulose, hemicellulose and lignin, is the largest renewable resource and can be transformed into value-added chemicals, materials and fuels by biorefining. [1] At present, lignocellulose refining is mainly focused on carbohydrate-derived sugar monomers, [2,3] while most lignin is used as a low-grade fuel. [1,4,5] As a natural aromatic polymer, researchers are dedicated to explore value-added applications of lignin to improve the economy of biorefining process, [1,4] including liquid fuel, [6][7][8] aromatic chemicals, [9,10] functional materials, [11][12][13][14][15] et al.…”

Lignin-based functional material has become an important way to realize the high-value utilization of lignin. However, the unstable performance limited its practical application, resulting from the inherent heterogeneity and uncertain extraction process of lignin. Here, a coupling process of the preparation of lignin-based silver nanoparticles (AgNPs) and carbohydrate refining was presented to realize the facile and stable preparation of AgNPs from lignocellulose, of which γ-Valerolactone (GVL)/H 2 O was used both as the extraction solvent of lignin and the catalyst for AgNPs synthesis in Ag 2 O/lignin system. The reaction rules and behaviors of AgNPs were systematically studied. Meanwhile, the separation rate of hemicellulose could exceed 90 % and a high-purity cellulose of 95.12 % was obtained. The enzymatic hydrolysis efficiency of residual cellulose from corncob was close to 71 %. The reliability of different biomass sources was also verified. This work provided a potential solution for improving the economic benefits of lignocellulose refining.

“…In the presence of initiators, the graft copolymerization reaction can occur subject to the appropriate selection of grafting monomers. This means that the exceptional properties of the grafted polymer can be fully exploited and incorporated into the overall modification process, so that the end products can demonstrate an improved performance and be utilized more extensively (Muranaka et al, 2016;Wang et al, 2015b). The graft copolymerization technique has been widely applied in several fields including mining.…”

“…Therefore, it is important to address the reconstruction of their structures through modification and subsequently make them widely usable (Gordobil et al, 2016). For example, lignosulfonate, a type of derivative in the sulfonation of lignin, is abundant in the effluents paper industry, the discharge of which can seriously contaminate the environment (Muranaka et al, 2016). Furthermore, because of its irregular structure, lignosulfonate can only be recycled for energy purposes; however, large amounts of active functional groups in lignin, such as hydroxy and benzene rings, will be wasted if lignosulfonate is only used for such purposes.…”

“…Those working with other natural molecular materials are also grappling with similar problems. Consequently, in order to ensure these polymer materials can be used in an environmentally friendly manner, their natural molecular structures have to be modified by physical, chemical, or biological modification methods (Kim et al, 2016;Muranaka et al, 2016).…”

This paper proposes the development of a novel coagulant for dust suppression in open-cast mines. Specifically, pretreated sodium lignin sulfonate and acrylic acid were first cross-linked, then the graft copolymerization of the intermediate product (the cross-linking product) and acrylamide was conducted and finally the resulting gelatinous substances were crushed. During the reaction process, N,N'-methylene-bis-acrylamide and ammonium persulfate were used as the cross-linking agent and initiator, respectively. Subsequently, the functional groups, crystalline structure, and thermal stability of the dust coagulant were examined by means of Fourier transform infrared spectra measurements, X-ray diffraction spectra measurements, and differential scanning calorimeter analysis. Moreover, single-factor experiments were conducted to explore the optimal synthesis condition. According to the experimental results, the coagulant achieved its optimal dust suppression performance under the following conditions: the mass ratio of lignin to acrylic acid was 1:3, the mass ratio of lignin to acrylamide was 2:7, the content of the cross-linking agent was 0.9%, the mass ratio of initiator to acrylamide was 2:100, the reaction temperature was set as 60 C, and the pH value was set as 7. Finally, the coagulant was measured for its swelling kinetics, viscosity, film-forming hardness, peeling strength, and ability to suppress dust. It can be concluded that the coagulant exhibits a very high standard of both dust suppression and wind resistance.
