Efficient synthesis of furfural from waste biomasses by sulfonated crab shell-based solid acid in a sustainable approach

TL;DR: Sunflower straw was pretreated in tartaric acid (1 wt%) at 180 °C for 60 min to enhance its reducing sugar recovery, 39.9% of lignin and 90.2% of xylan were eliminated as mentioned in this paper .

TL;DR: In this article , a biochar-based heterogeneous catalyst Sn-FS-RH was prepared using equal mass of fish scale (FS) and rice husk (RH) as carriers.

TL;DR: Researchers developed a biochar-based catalyst to efficiently co-produce xylooligosaccharides, furfural, and reducing sugars from yellow bamboo, achieving 80.3% furfural yield, 2.8 g/L xylooligosaccharides, and 17.2 g/L reducing sugars.

TL;DR: Choline chloride-oxalic acid deep eutectic solvents enhance enzymatic hydrolysis of rape straw by increasing cellulose accessibility and decreasing lignin surface area, with optimal pretreatment conditions achieved at a 3:1 molar ratio of choline chloride to oxalic acid.

TL;DR: In this article, the authors review the recent development of HMF and levulinic acid production from lignocellulosic biomass, which focuses on pretreatment of LCLs, preparation principle for HMF, and the upgrading application.

TL;DR: In this article, the application of metal/zeolite-supported bifunctional catalysts in the conversion of biomass sources into chemicals and fuels via hydrodeoxygenation (HDO) is discussed.

TL;DR: In this article, the effects of three metal chlorides including FeCl3, CuCl2, and AlCl3 on corn stover biomass pretreatment and enzymatic hydrolysis were studied under lower severity conditions (reaction temperature of 150-160 °C, salt concentration of 0.075-0.125M, and reaction time of 10 min).

TL;DR: In this article, a comparative study was performed by using the conventional heating method to prepare chitin and chitosan, with a degree of deacetylation of 82.73%, was successfully prepared in 24min via microwave irradiation method.
