Effect of steam treatment on chemical changes of wood components
Poplar wood chips were treated by steaming in different conditions. The chemical composition changes of milled wood were studied. The obtained results indicate hemicelluloses degradation, reduction of acetyl groups and formation of organic acid during the treatment. It was also found that steam trea...

Poplar wood chips were treated by steaming in different conditions. The chemical composition changes of milled wood were studied.
