The role of supercritical fluids in the fractionation pretreatments of a wheat bran-based biorefinery (Review)

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 […]

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 […]
