The 3D-printing fabrication of multichannel silicone microreactors for catalytic applications
Microstructured reactors (MSRs) are especially indicated for highly demanding heterogeneous catalysis due to the small channel dimensions that minimize diffusional limitations and enhance mass and heat transport between ... -
Application of a modeling tool to describe fly ash generation, composition, and melting behavior in a wheat straw fired commercial power plant
Ash behavior is a key operational aspect of industrial-scale power generation by means of biomass combustion. In this work, FactSage™ 6.4 software was used to develop and assess three models of wheat straw combustion in a ... -
Catalytic hydroprocessing of lignin β-O-4 ether bond model compound phenethyl phenyl ether over ruthenium catalysts
The catalytic hydroprocessing of phenethyl phenyl ether (PPE), a model compound of one of the most significant ether linkages within lignin structure, β-O-4, has been studied. Reactions were carried out using two ruthenium-based ... -
CO2 methanation over nickel catalysts: support effects investigated through specific activity and operando IR spectroscopy measurement
Renewed interest in CO2 methanation is due to its role within the framework of the Power-to-Methane processes. While the use of nickel-based catalysts for CO2 methanation is well stablished, the support is being subjected ... -
Desarrollo de catalizadores de cobalto y rodio para la producción de gas de síntesis por oxidación parcial de metano
Los procesos Gas-to-Liquid (GTL), basados en la transformación de gas natural en hidrocarburos sintéticos, son de gran interés para la valorización de los nuevos recursos que emergen actualmente fruto de la aparición de ... -
Encuesta de satisfacción de un proyecto de mejora de calidad del servicio aragonés de salud
Introducción: Según el informe de 2008 del Sistema Nacional de Salud, existe un 4,7% de los usuarios que opina que el sistema sanitario debería rehacerse por completo y casi un 27%, que es necesario introducir cambios ... -
Extraction of phenolic compounds from populus salicaceae bark
Lignocellulosic residues have the potential for obtaining high value-added products that could be better valorized if biorefinery strategies are adopted. The debarking of short-rotation crops yields important amounts of ... -
Modelizado y estudio experimental del comportamiento de las cenizas en instalaciones industriales de combustión de biomasa con tecnología de parrilla
El presente trabajo tiene por objetivo general el desarrollo de una metodología para el análisis y predicción del comportamiento de cenizas y compuestos inorgánicos generados en la combustión de biomasa a alta temperatura ... -
Performance comparison between washcoated and packed-bed monolithic reactors for the low-temperature Fischer-Tropsch synthesis
Washcoating and packing of Co-Re catalyst particles have been employed as structuring methods of parallel channel monoliths used in the low-temperature Fischer-Tropsch synthesis (FTS). These methods were compared with ... -
Production of aromatic compounds by catalytic depolymerization of technical and downstream biorefinery lignins
Lignocellulosic materials are promising alternatives to non-renewable fossil sources when producing aromatic compounds. Lignins from Populus salicaceae., Pinus radiata and Pinus pinaster from industrial wastes and biorefinery ... -
Renewable hydrocarbon production from waste cottonseed oil pyrolysis and catalytic upgrading of vapors with Mo-Co and Mo-Ni catalysts supported on γ-Al2O3
In this work, the production of renewable hydrocarbons was explored by the means of waste cottonseed oil (WCSO) micropyrolysis at 500◦C. Catalytic upgrading of the pyrolysis vapors was studied using α-Al2O3, γ-Al2O3, ... -
Rutas y retos para la valorización de biogás
Las tecnologías de digestión anaerobia para procesar corrientes residuales (fracción orgánica de residuos de vertedero, lodos de estaciones depuradoras de aguas residuales, purines, etc.) han originado un incremento de ...
