Process design for acidic and alcohol based deep eutectic solvent pretreatment and high pressure homogenization of palm bunches for nanocellulose production

Scientific Reports, Год журнала: 2024, Номер 14(1)

Опубликована: Март 30, 2024

Abstract This research aimed to study on nanocellulose production from palm bunch using process design and cost analysis. Choline chloride based deep eutectic solvent pretreatment was selected for high-purity cellulose separation at mild condition, followed by nano-fibrillation mechanical treatment. Three types of choline chloride-based solvents employing different hydrogen-bond donors (HBDs) namely lactic acid, 1,3-butanediol oxalic acid were studied. The optimal extraction condition chloride/lactic (ChLa80C) empty 80 °C bleaching yielding 94.96%w/w content in product. Size reduction ultrasonication high-pressure homogenization produced 67.12%w/w raw material. Different morphologies tunable the forms nanocrystals, nano-rods nanofibers dissimilar solvents. work offered a sustainable environmentally friendly as well provided analysis DES overview operating production. Application fabrication highly functional biodegradable material nanomedicine, electronic, optical, micromechanical devices is achievable near future.

Nanocellulose (CNF) has emerged as a promising alternative to synthetic petroleum-based polymers, but the conventional preparation process involves multiple tedious steps, heavily dependent on chemical input, and proves cost-inefficient. This study presented an, in situ ultrasound-assisted extraction using deep eutectic solvent (DES) based choline chloride oxalic acid for more facile production of CNF from raw durian husk fibers. FESEM analysis confirmed successful web-like nanofibril structure with width size ranging 18 26 nm. Chemical composition FTIR revealed selective removal lignin hemicellulose fiber. As compared post-ultrasound treatment, consistently outperforms, yielding higher yield finer fiber significantly reduced content. Integrating this eco-friendly ultrasonication-assisted one-pot method 7.5 min interval yielded highest 58.22 % minimal The superior delignification ability achieved through proposed protocol surpasses individual efficacy DES ultrasonication processes, neither which our experimental setup. single-step fabrication reduces usage streamlines steps web-structured that is ideal sustainable application membrane separator.

Deep Eutectic Solvent Pretreatment and Green Separation of Lignocellulose

Applied Sciences, Год журнала: 2024, Номер 14(17), С. 7662 - 7662

Опубликована: Авг. 30, 2024

Plant-based waste biomass with lignocellulose as an important component is produced in large quantities worldwide every year. The components of that typically exhibit high utilization value include cellulose and hemicellulose, well pentoses hexoses derived from their hydrolysis. As a pretreatment for the hydrolysis process, delignification pivotal step to enhance cellulose/hemicellulose accessibility achieve yields fermentable sugars. Additionally, deep eutectic solvents (DESs) are most widely used during fractionation due clean environmentally friendly attributes. DESs dissolve lignin by inducing amount β-O-4 bond cleavage partial carbon–carbon cleavage, retaining solid residue, while hemicellulose hydrolyzed DES pretreatment. This article provides comprehensive review influence separation process. Key factors such removal rate, sugar conversion product chemical structure critically reviewed assess feasibility employing separation.
