Study of hemicelluloses composition of different tree species, extraction using subcritical water with a batch cascade reactor

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 […]

Silica aerogels; alternative matrix for catalytic palladium nanoparticles

Effective routes to obtain more valuable products from biomass requires the design of efficient catalysts. Novel catalytic structures are therefore needed to overcome the present challenges. These novel structures require the integration of support active sites in a way that preserves their advantages and capabilities. Here, we introduce novel catalytic structures achieved by the integration […]

Disolution/Hydrolysis and repolymerization of lignin using ultrafast reactors in supercritical water

Efficient biomass fractionation is actually one of the major challenges posed to the biorefinery, because the complex structure of the plant cell wall and the high crystallinity of cellulose make the feedstock recalcitrant to separation into its components. Isolation/pretreatment methods that result in consistent types of lignin of high quality and purity are highly desirable. […]

Efficient production of soy-bean lecithin – pluronic L64® encapsulated quercetin particles in nanometric scale using SFEE and PGSS drying processes

Quercetin occurs in various fruits, vegetables and many other food components. According to preliminary studies, it has strong antioxidant-, antiviral-, antibacterial-, antihistaminic-, and anti-inflammatory effect. Due to these properties, quercetin is a highly promising material against a wide variety of diseases, including cancer. A major limitation for the clinical application of quercetin is its low […]

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), […]
