A novel physico-chemical model for hydrothermal fractionation of lignocellulosic biomass in a packed bed reactor is proposed in this work. The objective of this work is to reproduce the experimental behaviour with this model, including the effect of temperature, water flow and biomass properties. To do so, a novel reaction pathway based on two types […]
In this research, the heat and pressure integration possibilities of the supercritical water hydrolysis process are analyzed. The main objective is to improve the global energetic efficiency and therefore reduce the consumption of utilities.
Danilo Cantero, one of our former PhD students and current collaborator, has been recognized as one of MIT Technology Review Innovators Under 35 Argentina and Uruguay 2016, thanks to his innovations and developments on a high efficiency supercritical water reactor for cellulose hydrolisis. http://innovatorsunder35.com/innovators-under-35-argentina-uruguay http://innovatorsunder35.com/innovator/danilo-cantero
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 […]
Nowadays, the increasing energy demand, depletion of fossil fuels and global warming issues have motivated our society to look for alternative sources in order to produce energy, fuels and chemicals. In this sense, biomass is one of the most promising alternative carbon source which is renewable and potentially sustainable and thus a high research effort […]
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), […]
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 […]
