[:en] El pasado viernes 3 de Noviembre se presentaron los 23 proyectos de estudiantes de la Universidad de Valladolid que han sido galardonados en la octava edición de los “Premios Prometeo”. Estos premios tienen por objetivo apoyar e incentivar el desarrollo de prototipos orientados hacia el mercado. Entre los ganadores de esta edición se encuentran […]
Last week, University of Valladolid’s Chancellor, Daniel Miguel San José, welcomed the members of LightEnergy project. This project has been recently awarded with the Model2Market award (10,000 €). The project, development by a team constituted by 4 members of our research group, was selected from among 463 projects from 12 different Ibero-American countries. LightEnergy has […]
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.
Luis Miguel Sánz (Ph. D. student), Miriam Rueda (Ph. D. student), Ángel Martin (full professor) and Alexander Navarrete (Postdoc researcher) from High Pressure Processes Group (Universidad de Valladolid), have been rewarded with one of five awards of the Model2Market 2016 competition, the biggest event of Ibero-American entrepreneurship. The project, LightEnergy, about the use of hydrides […]
In this research, the heat and pressure integration possibilities of the supercritical water hydrolysis process are analyzed. The main objective is to improve the global energetic efficiency and therefore reduce the consumption of utilities.
The use of hydrogen as an energy vector stands as an interesting alternative to traditional energy sources, but it is necessary to find an efficient way of hydrogen storage for mobile devices. A possible solution is the use of solid materials containing hydrogen which would desorb it through thermal treatment on-board. Many solid hydrides that […]
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 […]
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 […]
Silica aerogel is a synthetic porous ultralight material derived from a gel, in which the liquid component of the gel has been replaced with a gas. The result is a solid with extremely low density and low thermal conductivity. Therefore these materials have been used in a variety of applications such as lightweight thermal and […]
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 […]
