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 […]

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 […]

One-pot conversion of D-Glucose into liquid straigh-chain alkanes over Ru-based catalysts

Regarding the shortage of fossil resources and energy sustainability, a great piece of attention has been paid to look for novel alternatives in order to obtain fuels, chemicals and energy.  Due to its high oxygen-to-carbon ratio, cellulosic biomass appears as a promising feedstock for its valorization into chemicals and building blocks. In recent years, direct […]

[Paper]: Bimetallic Ru:Ni/MCM-48 catalysts for the effective hydrogenation of D – glucose into sorbitol

Three different bimetallic Ru:Ni catalysts supported on a mesoporous silica MCM-48 were prepared by consecutive wet impregnations, with a total metal loading of ca. 3 % (w·w-1). Ru:Ni ratios spanned in the range of 0.15 – 1.39 (w·w-1) and were compared with the corresponding monometallic Ni/MCM-48. The catalysts so prepared were characterized by X-Ray Diffraction, […]

Hydrolysis of Cellulose in Supercritical Water: Reagent Concentration as a Selective Factor

Biomass is mainly composed by cellulose, hemicellulose and lignin. These components can be separated and then used as starting materials to produce interesting compounds via thermo-chemical processes such as hydrolysis. In the recent years there is an increasing interest in using supercritical water (SCW) as hydrolysis medium due to its suitability as environmentally friendly, non-toxic […]
