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 […]

Heterogeneous catalysts for the extraction of arabinoxylans from wheat bran

The conversion of biomass within biorefineries into chemicals and energy is seen as a real possibility for the substitution of fossil resources. Raw materials of high lignocellulosic content are an interesting option. Nowadays wheat bran is gaining interest as raw material for biorefineries due to its high content in polysaccharides. In this sense, arabinoxylans (AX), […]

[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 […]

Supercritical Water Oxidation (SCWO) with hydrothermal flame sustained by disaccharides without using co-fuel

The High Pressure Process Group of the University of Valladolid has recently proved that hydrothermal flames can be sustained by supercritical water oxidation of disaccharides, thus opening the possibility of processing different waste effluent containing sugars or biopolymers using this technology. Using the Cooled Wall Reactor with a hydrothermal flame inside, developed by the High […]
