NEW RESEARCH ARTICLE. PRETREATMENT EFFECT ON THE THERMAL DEGRADATION OF A FEEDSTOCK WITH LOW HEMICELLULOSE CONTENT: BRAZILIAN GINSENG

Pyrolysis is a well-known process for biomass upgrading, and a great deal of works are available about it. However, they focus on conventional lignocellulosic samples, and the information about any other less common samples, while still valuable, is very difficult to find. For instance, Brazilian ginseng (Pfaffia glomerata) is a feedstock without hemicellulose and a […]

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 […]

NEW RESEARCH ARTICLE: Microwave pretreatment to improve extraction efficiency and polyphenol extract richness. Effect on antioxidant bioactivity

Microwave assisted extraction advantages are widely recognised. However, its implementation at an industrial scale is restricted due to microwave limitations. In this work, a microwave pretreatment is proposed as an easy scale-up alternative. The double effect of this pretreatment on extraction yield and on product richness is assessed. Microwaves accelerate the extraction kinetics of most […]

NEW RESEARCH PAPER. MAXIMIZATION OF MONOMERIC C5 SUGARS FROM WHEAT BRAN BY USING MESOPOROUS ORDERED SILICA CATALYSTS

The hydrolysis process of a real fraction of arabinoxylans derived from wheat bran was studied. The influence of catalyst type and loading, reaction time and different metal cations were discussed in terms of the hydrolysis yield of arabinose and xylose oligomers as well as the formation of furfural as degradation product. A high yield of […]

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 […]

Kinetics analysis of solubilized biomass from a hydrolysis process by supercritical and subcritical water

A suitable technique to upgrade biomass is an essential point in order to make it possible to develop a sustainable economy based on biomass sources. One likely and green option to extract chemicals from biomass is hydrothermal processing. A process that only requires water, high temperature and pressure to fractionate biomass. In the same way, […]
