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 […]

[Thesis] Fractionation process of surplus biomass by autohydrolysis in subcritical water obtaining added value products by Florencia M. Yedro

In the past years, the challenge is a society based on the concept of bioeconomy. This term refers to the sustainable production and conversion of biomass into a range of food, health, fibre, industrial products and energy developed in futures biorefineries. The hydrothermal process has been proposed to develop sustainable and efficient conversion of natural […]
