文摘
- •
Torrefaction of softwood and hardwood is studied under different conditions.
- •
Solid-state 13C NMR is used to follow the structural changes of wood.
- •
The reactivities of lignins and hemicelluloses mainly govern the wood transformation.
- •
The behaviour of softwood under torrefaction is compared with hardwood.
- •
Oxygen and steam only impact the torrefaction kinetics above 280 °C.
