Tailored one-pot lignocellulose fractionation to maximize biorefinery toward versatile xylochemicals and nanomaterials

Abstract

Efficient fractionation of lignocellulose and refinery of all its components remain challenging. Here we describe the use of diols-tailored deep eutectic solvents for superior lignocellulose fractionation and maximizing refinery efficiency....

Toward cleaner production of nanocellulose: a review and evaluation

“…131 While, a solvent composed of a hydrogen bond donor and a hydrogen bond acceptor which is called a deep eutectic solvent (DES) has very similar physicochemical properties to ionic liquids, and can also be used to extract nanocellulose. 132,133…”

“…131 While, a solvent composed of a hydrogen bond donor and a hydrogen bond acceptor which is called a deep eutectic solvent (DES) has very similar physicochemical properties to ionic liquids, and can also be used to extract nanocellulose. 132,133 The IL, BmimHSO 4 , was used to treat MCC at 70-90 °C for 1 h to obtain CNCs for the first time. 134 The IL can be recovered after subsequent centrifugation and vacuum evaporation.…”

Formic acid–hydrogen peroxide treatment of furfural residue for production of nanocellulose, lignin, and nano-scale lignin

“…Nonetheless, the primary components of lignocellulosic biomass, cellulose and lignin, are tightly intertwined and embedded in the cell wall, resulting in difficult separation. 8 Up to now, several kinds of strategies have been developed to separate the main constituents of biomass. Chemical pulping processes such as alkali pulping and kraft pulping have been the mature technologies to obtain pulp in the papermaking industry, 9 which can achieve the separation of biomass components effectively.…”

Valorization of bamboo shoot shell waste for the coproduction of fermentable sugars and xylooligosaccharides

“…In the past, BSS was incinerated and sent to landfill sites rather than being used effectively, resulting in a considerable waste of resources. BSS has a great cost advantage over other lignocellulosic resources used as energy sources (Ma et al, 2022;Yu et al, 2022). As a type of food processing waste, BSS is inexpensive to acquire.…”

“…As the autohydrolysis reaction system is a weakly acidic environment, the number of produced fermentation inhibitors is relatively small (Kim et al, 2009;Kumar et al, 2009). Under highintensity autohydrolysis conditions, the processing of xylan by acetic acid results in shedding of xylan in fragments of different lengths, including XOS and xylose (Zhang et al, 2018;Yu et al, 2022). XOS is sensitive to the intensity of the reaction conditions, and highintensity conditions result in a decrease of DP for XOS.…”
