Wheat bran is a very interesting feedstock for lignocellulosic biorefineries. The recovery of proteins, oil and phytochemicals can be integrated with the fractionation of polysaccharides and lignin, adding value to a multi-product biorefinery concept. After reviewing the work previously reported in the literature concerning the use of sc-CO2 and subcritical and supercritical water, the present […]

NEW REVIEW: Understanding biomass fractionation in subcritical&supercritical water
[:en]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 […]
WCCE NEWS: AWARD TO THE BEST ORAL COMMUNICATION FOR OUR GROUP
[:en]Gianluca Gallina has been awarded during the 10th World Congress of Chemical Engineering held in Barcelona (Spain) for his lecture titled: New pilot plant for hemicellulose extraction with hot pressurized water in the International Symposium of Ligno-Cellulosic Materials. Additionally, this system was patented and detailed information about the work can be found in this paper: https://doi.org/10.1016/j.biortech.2017.09.155 […]
NEW RESEARCH PAPER. Hydrothermal extraction of hemicellulose from lab to pilot scale
A flow-through reactor for hemicelluloses extraction with hot pressurized water was scaled with a factor of 73. System performance was evaluated by comparing the temperature profile, extraction yield and kinetics of the two systems, performing experiments at 160 and 170 ºC, 11 bar for 90 min, using catalpa wood as raw material. Hemicellulose yields were […]
NEW RESEARCH PAPER. MAXIMIZATION OF MONOMERIC C5 SUGARS FROM WHEAT BRAN BY USING MESOPOROUS ORDERED SILICA CATALYSTS
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 […]
