Preparation and characterization of thermally stable cellulose nanocrystals via a sustainable approach of FeCl3-catalyzed formic acid hydrolysis

Xylitol can be obtained from hemicelullosic fraction of lignocellulosic materials containing D-xylose. Formic acid hydrolysis is widely used in lignocellulose pretreatment. However, formic acid hydrolysis wheat straw cannot be directly used as fermentation subsequently owing to various fermentation inhibitors, especially the formic acid in reaction system and released during pretreatment. This study describes main hydrolysis components and inhibitors prepared by hydrolysis of wheat straw with formic acid solution, and different detoxification methods ware used to romve the inhibitors. Study found treatment of wheat straw hydrolysate with overliming treatment and D311 ion-exchange resin had a good result on reduction formic acid and other main inhibitors, results showed which can eliminate 94% of residual formic acid and with only 15% reducion of xylose. To verify the effectiveness of different detoxification methods, hydrolysates of detoxification werr fermented by Candida.tropicalis AS2.1776, and the results also found that the hydrolysate treatmented with overliming treatment and D311 ion-exchange resin have the hightest xylitol yield.

Hydrolysis Residue

Utilization of wheat straw for bio-based chemicals production is a research focus. In this work, experiments were conducted to study the preparation conditions of activated carbon from formic acid hydrolysis residue of wheat straw applying response surface methodology. The effects of activation reaction temperature, retention time and activator quantity on the decolorizing capacity of activated carbon were dealt with in this paper. Optimal preparation conditions were abtained by response surface methodology as followed: the content of ZnCl2 solution was 14.2%, reaction temperature was 798°C and retained time was 30 mins with a decolorizing capacity of 15.8 mL methylene blue. Results indicated that the technology was available.
