Multimodal Characterization of Wood Pretreated with Continuous Steam Explosion: Impact of Physical and Chemical Features on Bioethanol Production
Résumé
Oak was pretreated by steam explosion at pilot-scale at several severities (residence time and temperature). Samples were characterized through a multimodal approach to quantify physico-chemical parameters, while enzymatic saccharification followed by fermentation into bioethanol were carried out. Aim of this study is to relate compositional and structural properties of pretreated wood to its biological conversion into bioethanol. Morphological and chemical markers were found to be highly correlated to bioethanol production.
