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 […]
[Thesis]: Heterogeneous Catalytic Copolymerization Reactions Of Carbon Dioxide And Propylene Oxide Over Polyalcohols Under Subcritical Conditions
Dr. Maria Pinilla de Dios defended her thesis on 23rd January 2017 at the University of Valladolid. The thesis projects was supervised by Dr Juan Garcia Serna from University of Valladolid and Dr. José Román Galdámez Peña from Technological Center of Repsol, while the International supervisor was Prof. Tapio Salmi from the Laboratory of Industrial Chemistry and Reaction Engineering […]
Multistage Pilot Plant for the extraction of hemicellulose with subcritical water
Hemicellulose is a natural polymer, made up of several sugars. It can be used to replace oil in many applications, like: production of biofuels; production of films for packaging; production of gels for drug delivery; production of xylitol, compound of great interest in the medical field; production of furfural, which is used in the production […]
[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 […]
