    Curso abierto de ayuda para la elaboración del Trabajo Fin de Grado en los Grados en Química e Ingeniería Química

    Get PDF
    Este proyecto llevará a cabo el desarrollo de un curso abierto que sirva a los estudiantes como guía de ayuda a la hora de elaborar su Trabajo Fin de Grado (TFG) en los Grados de Química e Ingeniería Química. Se incluirá una descripción de herramientas que los estudiantes puedan emplear en el desarrollo de sus TFG. Éstas serán seleccionadas de acuerdo con la experiencia de los miembros del Grupo y en función de las necesidades de los estudiantes. El curso resultante se editará para libre acceso a través del portal iTunes U, de ámbito internacional, convirtiéndose en el primer curso UCM ofertado en esta plataforma (tras consulta y aprobación del Vicerrectorado de Innovación; de no ser así, se alojará en alguna otra plataforma de amplia difusión). Se aprovechará la accesibilidad ofertada a los estudiantes por iTunes U para poner a su disposición el material elaborado logrando una gran difusión, incrementándose la visibilidad internacional de la UCM. El material de ayuda elaborado para el curso se presentará tanto en español como en inglés, para facilitar su uso por alumnos visitantes de la UCM, favoreciendo la movilidad de los estudiantes en el marco del EEES. Este material también se adaptará para poder ser empleado de forma directa, totalmente o en forma de módulos, en el Campus Virtual UCM

    Fractionation of Pinus radiata by ethanol-based organosolv process

    The lignocellulosic materials are promising feedstock to produce biofuels and bioproducts in the biorefnery framework. However, a pretreatment step is required to disrupt lignin-carbohydrate complex. In this work, the fractionation of Pinus radiata wood into its main components, cellulose-rich delignifed solid, recovered lignin after precipitation, and solublein-black liquor hemicellulose, was studied. For this purpose, an organosolv process employing ethanol/water mixture as solvent in absence of a catalyst was carried out. The efects of operating conditions on delignifed solid were evaluated by using a 23 central composite experimental design, being the responses delignifed solid yield, delignifcation degree, hemicellulose content, and glucan content. The variables studied were temperature (170–200 °C), time (50–100 min), and ethanol concentration (40–60%). The increase of organosolv severity (temperature and time) and reduction of ethanol concentration favor the glucan enrichment of delignifed solid, due to lignin removal and hemicellulose solubilization. A glucan content of more than 66% is obtained by applying temperature higher than 195 °C and time longer than 90 min, when 40 wt% alcohol concentration is used. The liquid fraction obtained during the organosolv process (black liquors) was used to recover lignin and hemicellulosic fractions solubilized. Furthermore, hemicellulose and lignin content of delignifed solid was correlated with the thermal stability measured as T10%

    Technoeconomic Assessment of a Biomass Pretreatment + Ionic Liquid Recovery Process with Aprotic and Choline Derived Ionic Liquids

    Ionic liquids have shown promising results in biomass pretreatment; however, an extensive water washing step is necessary. This fact increases not only the processing costs but also those associated with the ionic liquid recovery step. In this work, Eucalyptus globulus wood pretreated with two acetate-based ionic liquids, namely 1-ethyl-3-methylimidazolium acetate and choline acetate, has been washed with increasing volumes of water in order to analyze the influence of the amount of washing water used on the subsequent enzymatic hydrolysis stage and on the IL recovery costs. Vapor−liquid equilibria data of recovered ionic liquid/water mixtures have been determined to simulate the IL recovery step with Aspen Plus, calculating the operating costs using the Aspen Plus Economics Analyzer afterward. [Emim][OAc] was more efficiently washed and more effective toward wood pretreatment than [Ch][OAc]. Both IL/water systems were successfully modeled, and simulation studies showed that incremental volumes of water led to higher operating costs in the IL recovery step that are compensated with less IL makeup costs. Therefore, this work offers a technoeconomical analysis of the IL recovery step in a real biorefinery pretreatment process as a function of the volume of water used in the pretreated wood washing stage
