In this research, the biochar-based tin-loaded heterogeneous catalyst Sn-NUS-BH was used for efficient catalytic conversion of corncob (CC) in a green biphasic system cyclopentyl methyl ether–water (CPME-H2O). By optimizing conditions (CPME to H2O ratio, dosage, reaction time, and temperature), stubborn structure corncobs maximally disrupted. The chemical composition structural characteristics (accessibility, lignin surface area, hydrophobicity) CC before after treatment were assessed, demonstrating that natural physical barriers disrupted effectually eliminated. accessibility enhanced from 137.5 mg/g 518.5 mg/g, area declined 588.0 m2/g 325.0 m2/g, hydrophobicity changed 4.7 L/g 1.3 L/g. Through at 170 °C 20 min, furfural (11.7 g/L) xylooligosaccharides (4.5 acquired pretreatment liquor. residual could be enzymatically saccharified into reducing sugars yield 65.2%. combination with tin-based biochar chemocatalyst combined solvent CPME-H2O shows great promise valorization biomass.

Preparation and Characterization of Oil Palm Empty Fruit Bunch-Based Cellulose for Levulinic Acid Production

Malaysian Journal of Science and Advanced Technology, Год журнала: 2024, Номер unknown, С. 374 - 382

Опубликована: Сен. 2, 2024

This study investigates the process of isolating and characterizing cellulose from Oil Palm Empty Fruit Bunch (OPEFB) fibers collected Sime Darby Plantation, Selangor. The OPEFB underwent a sequence chemical processes including dewaxing, alkali pretreatment bleaching, to isolate cellulose. resulting was analyzed for its composition, crystallinity yield hydrolysis products. Comparative analysis with recent studies indicates that content isolated falls within reported range, relatively lower lignin suggesting successful removal during treatments. index significantly increased after post-treatment, reaching 76.43%, which is higher than some values. yielded levulinic acid (LA) levels comparable commercial cellulose, OPEFB-based producing an LA 8.98% 9.73% highlights potential as viable source high-quality production sugars LA.

Abstract Magnetic nickel oxide multi‐walled carbon nanotubes (MWCNT‐NiO) were employed in the immobilization of xylanase from Thermomyces lanuginosus , after modification with (3‐glycidoxypropyl)trimethoxysilane or 3‐aminopropyltriethoxysilane (APTES). The APTES‐derivatized MWCNT‐NiO particles activated glutaraldehyde to immobilize T. via covalent attachment. (3‐glycidoxypropyl)trimethoxysilane‐derivatized directly used for xylanase, formed epoxy groups converted aldehyde groups. free had maximum activity at pH 7.5, whereas immobilized samples showed an optimum 7.0. temperature was 60°C samples. thermal stability increased 7 and/or 12 folds immobilization. results xylooligosaccharide synthesis that main xylooligosaccharides xylobiose, xylotriose, and xylotetraose Furthermore, effect enzyme loading could be found, increase this parameter promoted xylobiose xylotriose amounts slightly increased, amount decreased. retained least 80% their initial five reuses 7.0 60°C. show new preparations easily separable, thermally stable, reusable xylooligosaccharides.
