  3. David Alique
David Alique (Madrid, 1981) reached a degree in Chemical Engineering from Rey Juan Carlos University in 2004. After working in practice for a short period in Repsol S.A. oil refinery located in Cartagena, Murcia (Spain), he started his Ph.D. studies that were completed in 2014 with the maximum grade of “Sobresaliente Cum Laude” and Extraordinary Doctorate Mention. His main research is based on the development of H2-selective Pd-dense membranes and their application in independent separators or membrane reactors. His mobility experience includes four months in the Department of Chemical Engineering, Mining and Environmental Technologies of the University of Bologna (Bologna, Italy) and 6 months in the Italian National Agency for New Technologies, Energies and Sustainable Economic Development (Frascati-Roma, Italia). He has participated in 13 competitive research projects, being the main investigator in some of them. Moreover, he has also participated in multiple tasks for dissemination of the scientific results, including more than 50 communications in International conferences, thirty publications in high-quality international journals with a JCR index, and four book chapters. His activity as a reviewer of more than two hundred scientific manuscripts for diverse international journals also deserves to be highlighted.
Related to his teaching experience, he has taught more than 2,400 hours in both practice and theoretical courses for multiple official engineering grades including, among others, Chemical, Energy, Environmental, Industrial Technologies, Mechanical, Materials, and Aerospace. Moreover, he supervised multiple final degree/master's projects and participated in pre-university programs promoted by Rey Juan Carlos University. Finally, it should be mentioned his participation in various activities of teaching innovation to improve his daily work as a professor.

      Show 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.
