The influence of thermochemical treatments on the lignocellulosic structure of wheat straw as studied by natural abundance 13C NMR

- Thermochemical biorefinery products of wheat straw are studied with solid state NMR.
- Aquathermolysis breaks lignin C4 ether bonds and converts hemicellulose in furfural.
- Removal of ash elements inhibits pyrolysis and enhances yield of levoglucosan.
- A pyrolysis resistant cutin type of waxy polymer seems present in pyrolysis chars.
