[Paper]: Hydrothermal fractionation of grape seeds in subcritical water to produce oil extract, sugars and lignin

The fractionation of grape seeds as a model biomass was studied using a combination of two processes: solvothermal extraction using ethanol and hydrothermal fractionation-autohydrolysis process in a semicontinuous reactor using subcritial water. Around 70% of the polyphenols were extracted in the first step and close to 80% of the sugars in the second step.

[Paper] Prediction of residence time distributions in supercritical hydrothermal reactors working at low Reynolds numbers

This work presents a methodology to characterise continuous hydrothermal flow systems both experimentally and numerically, working at low Reynolds numbers. Under these conditions traditional computational approaches in the field are of limited use, so new tools are in demand. Residence time distributions (RTD) experiments are carried out using a purpose built continuous flow rig featuring […]

[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 […]

[Paper] The use of modelling to understand the mechanism of hydrogen peroxide direct synthesis from batch, semibatch and continuous reactor points of view

Hydrogen peroxide direct synthesis was experimentally studied in three different reactors, namely the batch, semibatch and trickle bed reactors (TBR), using a new promising catalyst based on Pd/K2621. Excellent results were obtained from the experimental point of view, achieving high H2O2 selectivities, around 90% for a short contact time in the batch reactor, 60% in […]
