NEW REVIEW: Understanding biomass fractionation in subcritical&supercritical water

Biomass fractionation into its individual building blocks poses a major challenge to the biorefinery concept. The recalcitrance of the lignocellulose matrix and the high crystallinity of cellulose make typical feed stocks difficult to separate into their components. Hydrothermal processing fractionates biomass by its hydrolysis. However, a deep knowledge of hydrolysis principles is required since an […]

Multistage Pilot Plant for the extraction of hemicellulose with subcritical water

Hemicellulose is a natural polymer, made up of several sugars. It can be used to replace oil in many applications, like: production of biofuels; production of films for packaging; production of gels for drug delivery; production of xylitol, compound of great interest in the medical field; production of furfural, which is used in the production […]

Disolution/Hydrolysis and repolymerization of lignin using ultrafast reactors in supercritical water

Efficient biomass fractionation is actually one of the major challenges posed to the biorefinery, because the complex structure of the plant cell wall and the high crystallinity of cellulose make the feedstock recalcitrant to separation into its components. Isolation/pretreatment methods that result in consistent types of lignin of high quality and purity are highly desirable. […]

[Paper] Optimal conditions for hemicelluloses extraction in a semi-continuous reactor

Optimal conditions for hemicellulose extraction from wooden biomass in a semi-continuous system have been assessed in this work. This study would constitute the first stage for a profitable and green industrial process. Eucalyptus globulus was selected as raw material due to its low water consumption, high growth and its efficiency in lignocellulose production. Download for […]
