The hydrolysis process of a real fraction of arabinoxylans derived from wheat bran was studied. The influence of catalyst type and loading, reaction time and different metal cations were discussed in terms of the hydrolysis yield of arabinose and xylose oligomers as well as the formation of furfural as degradation product. A high yield of […]

Aerogels supported ionic liquid phase to catalyze the reaction between CO2 + Epoxides
Visiting Portuguese researcher in the HPP Group of the University of Valladolid is studying the comparison of using bulk ionic liquids as reaction solvent and catalyst for the coupling reaction between CO2 and limonene oxide, with the utilization of an ionic liquid phase adsorbed into alginate aerogels (SILP) in the frame of project AQACO2NV and […]
[Thesis]: Heterogeneous Catalytic Copolymerization Reactions Of Carbon Dioxide And Propylene Oxide Over Polyalcohols Under Subcritical Conditions
Dr. Maria Pinilla de Dios defended her thesis on 23rd January 2017 at the University of Valladolid. The thesis projects was supervised by Dr Juan Garcia Serna from University of Valladolid and Dr. José Román Galdámez Peña from Technological Center of Repsol, while the International supervisor was Prof. Tapio Salmi from the Laboratory of Industrial Chemistry and Reaction Engineering […]
[Paper]: Extraction of arabinoxylans from wheat bran using hydrothermal processes assisted by heterogeneous catalysts
The extraction/hydrolysis process of arabinoxylans from destarched wheat bran was studied in this work using different mesoporous silica supports and the corresponding RuCl3-based catalysts. The effects of temperature, time, catalyst supports and ruthenium catalysts were investigated and discussed in terms of the arabinoxylans extraction yield and their polymerization degree. Relatively high temperatures (180 ºC), short […]

Downstream processing of model polyalcohols by catalytic copolymerization reaction of CO2 and propylene oxide under subcritical conditions
CO2 can be used in copolymerization reactions as a C1 feedstock. It can be inserted into the polymer chain. Through the mechanism of Ring Opening Polymerization, propylene oxide is a suitable monomer for such reaction.
[Thesis]: Development of functionalized aerogels for applications as catalysts and hydrides matrix
Dr. Luis Miguel Sanz defended his thesis on Tuesday 8th November 2016 at the University of Valladolid. Urban air pollution is a serious problem in many large cities in the world. In addition, the increasing share of solar and wind in the energetic mix and its fluctuating nature, demands the development of technologies for storage […]
