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 […]

Meet María Anderez – PhD student on CO2 reduction project

She comes from Leibniz Institute for Catalysis, LIKAT (Rostock, Germany), where she focused on the homogeneous catalytic dehydrogenation of hydrogen carriers. During her thesis, she will study the CO2 reduction using lignocellulosic derivatives as reductans. CO2 reduction in hydrothermal environment using biomass as reductant In the last decades, CO2 has attracted more attention for its […]

[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 […]

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 […]
