The study explores using sago palm fronds (SPF) for eco-friendly high-purity cellulose production. It employs prehydrolysis, soda cooking with 2-methylanthraquinone (MAQ) as a green additive, and totally chlorine-free (TCF) bleaching. Optimal conditions of prehydrolysis at 150°C for 3 hours, followed by soda-MAQ cooking at 160°C for 1.5 hours with 0.03% MAQ and 23% active alkali, produce high-purity cellulose with desirable properties. The soda-MAQ method excels in delignification, improving pulp yields and reducing kappa numbers. Additionally, lignin recovery holds potential for biorefinery applications.

One-pot Eucalyptus globulus wood fractionation in acid-catalyzed mixtures of water and 1-pentanol: an optimization study

© Author

Eucalyptus globulus wood underwent processing using a mixture of 1-pentanol, water, and diluted acid catalyst. Response Surface Methodology assessed the effects of variables like 1-pentanol proportion, catalyst charge, and temperature on wood solubilization and phase composition. Statistical optimization identified optimal conditions, achieving extensive lignin and hemicellulose removal with good cellulose selectivity. Enzymatic hydrolysis yielded near-complete conversion, confirming 1-pentanol's potential for Eucalyptus globulus wood-based biorefineries.

The Journal of Wood Science is the official journal of the Japan Wood Research Society. This journal provides an international forum for the exchange of knowledge and the discussion of current issues in wood and its utilization. The journal publishes original articles on basic and applied research dealing with the science, technology, and engineering of wood, wood components, wood and wood-based products, and wood constructions. Articles concerned with pulp and paper, fiber resources from non-woody plants, wood-inhabiting insects and fungi, wood biomass, and environmental and ecological issues in forest products are also included. In addition to original articles, the journal publishes review articles on selected topics concerning wood science and related fields. The editors welcome the submission of manuscripts from any country.
