Chemical and Environmental Engineering Group

David Alique was born in 1981 and he was graduated in Chemical Engineering by University Rey Juan Carlos since 2004. His academic formation was continuated with the PhD program in Chemical Engineering, Environment and Materials of both Rey Juan Carlos and Castilla la Mancha universities. Currently, after obtaining the Advanced Studies Certificate in 2006, he combines his research activities with teaching assignments.
His research focuses primarily on production and purification of hydrogen through selective membranes, mainly composed of palladium or alloys. It is important to include the contributions presented for several international conferences and the two fellowships awarded by the European Commission Research through the Marie Curie Actions for attendance at courses "Nanostructured materials and membranes, synthesis and characterization" and "Nanostructured materials and membranes for energy ". Moreover, he enjoyed of a predoctoral stay during 4 months at the “Dipartamento di Ingegneria Chimica e delle Tecnologie Ambientali Mineraria, Università degli Studi di Bologna”, under the supervision of Prof. Giulio Sarti Cessare.
Regarding his teaching activities, it is important to outline his participation in several matters at graduate and post-graduate levels and his functions as co-director in more than 10 projects, mainly related to Chemical Engineering.

    Summary : The controversy generated by the use of agricultural edible crops for energetic applications has increased the interest of microalgae for biofuels production. Microalgae do not need large fields for its cultivation and can grow quickly. Microalgae are a renewable, sustainable and non-polluting feedstock that contribute to reduce the greenhouse gas emissions because they use CO2 in their growth. For these reasons, the overall aim of this project is the sustainable production of hydrogen and bio-oil from microalgae.
    The microalgae hydrothermal liquefaction (HTL) requires lower temperatures than pyrolysis and high pressures to maintain liquid water. This is an advantage because a highly energy demand step like microalgae drying is not needed in liquefaction with the subsequent cost saving. Based on the previous results achieved by the research group (CTQ2013-44447-R project) the bio-oil obtained from one step HTL contains high oxygen (10-20 %) and nitrogen (1-8 %) amounts which are responsible of bio-oil low stability and also of the NOx emissions during bio-oil combustion. To solve these problems, a two-step HTL process is planned in this project. The first step is carried out at low temperature (T< 200 ºC) and provides an aqueous stream by decomposition of proteins and short chain carbohydrates. Next, the solid fraction undergoes a second stage of HTL at higher temperature (T = 250-350°C) with the aim of achieving a bio-oil with low content of nitrogen and oxygen. The second stage of liquefaction also produces a gas stream mainly containing carbon dioxide that may be recirculated to the cultivation of the microalgae.
    The aqueous fractions from both stages of liquefaction can be revalued through the production of high purity hydrogen by catalytic steam reforming in a membrane reactor. Hydrogen can be used as fuel using conventional technologies (combustion engines) or in development ones (fuel cells). Additionally in this project, oxidative steam reforming reactions will be done in order to reduce the energy needs of the process and to avoid catalysts deactivation by coke deposition.
    From the environmental point of view, the project will use tools like the Life Cycle Analysis (LCA) to assess the emissions and energy balances, checking that they conform to a model of sustainable development.
