“…Previously, p-toluenesulfonic acid solution has been used to dissolve and remove lignin from waste wheat straw, bark, and wood in order to improve cellulose nanofibrillation and further to produce lignin containing CNF using disk grinding (Bian et al, 2017b;Bian et al, 2019;Bian et al, 2018;Dou et al, 2019). Recently, it was also found that lignin can be solubilized in some acidic deep eutectic solvents (ADESs), such as choline chloride-lactic acid (ChCl-LA) and choline chloride-oxalic acid (ChCl-OA) (Alvarezvasco et al, 2016;Guo et al, 2019;Hong et al, 2016;Liu et al, 2017b;Lynam et al, 2017;Shen et al, 2019).…”

“…The term acid hydrotrope fractionation was first proposed and applied to fractionate lignocelluloses only recently by Zhu and co‐workers at the USDA Forest Service, Forest Products Laboratory [50] . They used p ‐toluenesulfonic acid ( p ‐TsOH) to fractionate a variety of plant biomass, such as wood [66,67] as well as herbaceous and forest biomass [68,69] . They also found some novel acid hydrotropic agents such as MA [51] that can also functionalize lignin for efficient fractionation.…”

This Minireview provides a comprehensive discussion on the potential of using acid hydrotropes for sustainably fractionating lignocelluloses for biorefinery applications. Acid hydrotropes are a class of acids that have hydrotrope properties toward lignin, which helps to solubilize lignin in aqueous systems. With the capability of cleaving ether and ester bonds and even lignin‐carbohydrate complex (LCC) linkages, these acid hydrotropes can therefore isolate lignin embedded in the plant biomass cell wall and subsequently solubilize the isolated lignin in aqueous systems. Performances of two acid hydrotropes, that is, an aromatic sulfonic acid [p‐toluenesulfonic acid (p‐TsOH)] and a dicarboxylic acid [maleic acid (MA)], in terms of delignification and dissolution of hemicelluloses, and reducing lignin condensation, were evaluated and compared. The advantages of lignin esterification by MA for producing cellulosic sugars through enzymatic hydrolysis and lignin‐containing cellulose nanofibrils (LCNFs) through mechanical fibrillation from the fractionated water insoluble solids (WIS), and for obtaining less condensed lignin with light color, were demonstrated. The excellent enzymatic digestibility of maleic acid hydrotropic fractionation WISs was also demonstrated by comparing with WISs from other fractionation processes. The recyclability and reusability of acid hydrotropes were also reviewed. Finally, perspectives on future research needs to address key technical issues for commercialization were also provided.

“…The incorporation of lignin as a component of cellulose membranes was reported by Farooq et.al., whereby lignin-containing membranes were applied to absorb UV radiation [ 19 ]. Dou et al reported the manufacture of highly hydrophobic films from willow bark lignocellulose [ 20 ], and physisorption studies of CO 2 capture by lignin-derived carbons have also been reported [ 6 , 21 , 22 ].…”

Nanocellulose membranes based on tunicate-derived cellulose nanofibers, starch, and ~5% wood-derived lignin were investigated using three different types of lignin. The addition of lignin into cellulose membranes increased the specific surface area (from 5 to ~50 m2/g), however the fine porous geometry of the nanocellulose with characteristic pores below 10 nm in diameter remained similar for all membranes. The permeation of H2, CO2, N2, and O2 through the membranes was investigated and a characteristic Knudsen diffusion through the membranes was observed at a rate proportional to the inverse of their molecular sizes. Permeability values, however, varied significantly between samples containing different lignins, ranging from several to thousands of barrers (10−10 cm3 (STP) cm cm−2 s−1 cmHg−1cm), and were related to the observed morphology and lignin distribution inside the membranes. Additionally, the addition of ~5% lignin resulted in a significant increase in tensile strength from 3 GPa to ~6–7 GPa, but did not change thermal properties (glass transition or thermal stability). Overall, the combination of plant-derived lignin as a filler or binder in cellulose–starch composites with a sea-animal derived nanocellulose presents an interesting new approach for the fabrication of membranes from abundant bio-derived materials. Future studies should focus on the optimization of these types of membranes for the selective and fast transport of gases needed for a variety of industrial separation processes.
