CATHYCEL – Ganador Greenweekend Valladolid 2017
El proyecto CATHYCEL, catalizadores para hidrogenación de celulosa y productos lignocelulósicos ha sido presentado por nuestro investigador Alberto Romero y ha ganado la Greenweekend Valladolid 2017. El vídeo explica este concepto de biorrefinería. https://youtu.be/lePesznZO4M
Kinetics analysis of solubilized biomass from a hydrolysis process by supercritical and subcritical water
A suitable technique to upgrade biomass is an essential point in order to make it possible to develop a sustainable economy based on biomass sources. One likely and green option to extract chemicals from biomass is hydrothermal processing. A process that only requires water, high temperature and pressure to fractionate biomass. In the same way, […]
[Thesis]: Innovative Strategies to Enhance Properties of Solid Hydrogen Storage Materials Based on Hydrides
Dr. Miriam Rueda defended her thesis on Friday 18th November 2016 at the University of Valladolid (international PhD by University of Pavia). Nowadays, the development of renewable energy resources is attracting much more attention in order to reduce economic and environmental problems associated to the use of fossil fuels. However, their production is variable during time […]
[Course]: Dynamics of Chemical Reaction Systems
For November 7th to November 10th, Prof. Antonio Alvarez Alonso, from (Bio)Process Engineering Group at IMM-CSIC (Vigo, Spain), will teach the course “Dynamics of Chemical Reaction Systems“. The course will be held at classroom 3 at the department of Systems Engineer (Alfonso VIII). First session will start at 16:00, schedule will be fix subsequently. The objective of this course […]
Kinetic model for hydrothermal fractionation of lignocellulosic biomass in a lab-scale biorefinery
A novel physico-chemical model for hydrothermal fractionation of lignocellulosic biomass in a packed bed reactor is proposed in this work. The objective of this work is to reproduce the experimental behaviour with this model, including the effect of temperature, water flow and biomass properties. To do so, a novel reaction pathway based on two types […]

[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 […]
