The hydrolysis process of a real fraction of arabinoxylans derived from wheat bran was studied. The influence of catalyst type and loading, reaction time and different metal cations were discussed in terms of the hydrolysis yield of arabinose and xylose oligomers as well as the formation of furfural as degradation product. A high yield of […]

Study of hemicelluloses composition of different tree species, extraction using subcritical water with a batch cascade reactor
Hemicelluloses from 10 different tree species commonly growing in the Castilla y Leon region have been extracted with a batch cascade reactor. Raw materials came from tree branches, cut during the seasonal pruning. The aim was to correlate the yield of hemicellulose achieved through the extractions, with the total composition and the structure of the […]
[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 […]
[Paper] Hydrothermal fractionation of grape seeds in subcritical water to produce oil extract, sugars and lignin: biorefinery example
In the present work, the fractionation of grape seeds was studied using solvothermal extraction and a hydrothermal fractionation-hydrolysis process focused in the production of added value components. The grape seeds were hydrothermally treated using a multi-step two-solvent and temperature profile fractionation in order to separate the added value components from hemicelluloses, celluloses and lignin in […]
