Aging wine lees are water-wastes produced during the wine aging inside wood barrels that can be considered as alternative sources of bioactive compounds. Phenolic characterization and antioxidant activity (AA) measurements of wines lees solid-liquid extracts have been undertaken on a dry extract (DE) basis. Solvents with different polarities (water, methanol, ethanol, two hydroalcoholic mixtures and […]

9th Conference Horizon2020: Fomentando la Innovación Impulsando el Conocimiento
Last November the 16th, CDTI celebrated at Valladolid the 9th edition of the national conference about Framework Program about Researching and Innovation of the European Union. More than 450 stakeholders reunited to analyze the progress of Horizon 2020 during its first years. The meeting was organized by CDTI and the Economy, Industry and Competitiveness Ministry […]
Scaling-Up Of SFEE, Identification Of Process Parameters On Product Characteristics And Economic Impact
A scaled-up SFEE equipment (Fig 1) was designed and used for producing sufficient amount of aqueous suspensions for PGSS-drying treatment. Using PGSS-drying water content of aqueous suspensions was extracted, and hence long-term stability of product was increased, without irreversible change on its morphology. The scaled-up SFEE equipment consists of an electrically tempered extractor vessel with […]
Start up of a new continuous facility for the hydrothermal reduction of CO2
The high pressure processes of the University of Valladolid have built a continuous pilot plant for studying the scale up of hydrothermal CO2 reduction processes. The hydrothermal CO2 reduction (in aqueous media at high pressure and temperature) is a promising method for converting the CO2 in chemicals and fuels such as formic acid, methanol or […]
New method to connect Aspen Plus with Ansys Fluent CFD simulations
Traditional CFD simulations have been limited by the calculation of thermodynamic properties for uncommon compounds or non-ideal operating conditions. A method of integration of Aspen Plus®, a commercial process engineering simulator, and Ansys Fluent®, a CFD simulator, has been developed. The method of integration is based in the intercommunication of both programs using Matlab® and […]
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, […]
Multistage Pilot Plant for the extraction of hemicellulose with subcritical water
Hemicellulose is a natural polymer, made up of several sugars. It can be used to replace oil in many applications, like: production of biofuels; production of films for packaging; production of gels for drug delivery; production of xylitol, compound of great interest in the medical field; production of furfural, which is used in the production […]
Hydrolysis of Arabinoxylans From Wheat Bran into Monomeric Sugars Over Heterogeneous Catalysts
The aim of this work is to study the conversion of arabinoxylans from wheat bran into monomeric sugars, namely xylose and arabinose, using RuCl3-based catalysts. Arabinoxylans (AX), which are the major components of wheat bran, can be converted into arabinose and xylose by a hydrolysis process (Fig. 1). These two sugars are very interesting platform […]
One-pot conversion of D-Glucose into liquid straigh-chain alkanes over Ru-based catalysts
Regarding the shortage of fossil resources and energy sustainability, a great piece of attention has been paid to look for novel alternatives in order to obtain fuels, chemicals and energy. Due to its high oxygen-to-carbon ratio, cellulosic biomass appears as a promising feedstock for its valorization into chemicals and building blocks. In recent years, direct […]
Selective conversion of sugar beet pulp into sugars and high value products by supercritical water hydrolysis
Agro-industrial biomass are considered promising resources for the production of organic carbon-based chemicals and materials. This is the case of sugar beet pulp (SBP), which is the major by-product in beet sugar industry.
