[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.

Energy Recovery From Effluents Of Supercritical Water Oxidation Reactors

Supercritical Water Oxidation (SCWO) reactors can process waste effluents achieving high conversions without producing pollutants –apart from carbon dioxide-, but the required extreme pressure and temperature operational conditions entail high-energy operational expenditure. Because of this, it is necessary to study reasonable solutions which are able to solve this part of the process with a viable […]

Light hydrogen storage materials for mobile applications

Nowadays, economy and society depend on the use of fossil fuels. This dependence generates severe environmental, economic and political problems. For this reason, the development of alternative energy sources which are able to help to mitigate these problems is a priority research and development area. In recent years, this interest has boosted important advances in […]

Hydrogen storage in microparticles of silica aerogel for mobile applications

The application of fuel cells using hydrogen as their energy source in vehicles or electronic equipment requires the development of new hydrogen storage devices. Current needs: The simplest and most obvious storage solutions such as compressed gas bottles or cryogenic tanks have important disadvantages due to the low gravimetric/volumetric density of the former (40g/L at […]
