Degradation mechanism of monosaccharides and xylan under pyrolytic conditions with theoretic modeling on the energy profiles

- Xylan, mannose, galactose, and arabinose were used to represent hemicellulose.
- The evolution of typical pyrolysis products were illustrated by TG-FTIR.
- Three possible routes for xylose pyrolysis were discussed via DFT calculation.
- Insights were obtained into the formation pathways of furans and acetic acid.
