T
he use of bio-energy as a renewable alternative to fossil fuels is nowadays attracting more and more attention. The bio-
fuel from biomass seems to be a potential energy substitute for fossil fuels since it is a renewable resource that could
contribute to sustainable development and global environmental preservation and it appears to have significant economic
potential. Liquid fuels can be obtained from fast pyrolysis of lignocellulosic biomass, where fast pyrolysis is a promising route
because the process takes place at moderate temperatures, in absence of air and with a short hot vapor residence time. However,
these liquid fuels have poor quality due to their low volatility, high viscosity, low heating value, a high oxygen content and
poor chemical stability. This high oxygen content is due to the presence of oxygen-containing compounds such as alcohols,
aldehydes, ketones, furans and phenols. In this sense, catalytic hydrodeoxygenation (HDO) is one the most efficient process
to remove oxygen from these liquid fuels. In this context, the catalyst design is of upmost importance to achieve a high degree
of deoxygenation, and bifunctional catalysts are required to achieve high degrees of activity. Noble metal and non-noble
metal based catalysts will be evaluated in HDO of model molecules in order to get further insight about the important role
of the active phase. Transition metal phosphides have shown excellent catalytic performances due to their good hydrogen
transfer properties that diminishes the amount of metal exposed, avoiding, as much as possible, the deactivation, and modifies
the electronic density of the catalyst leading to solids that favors the HDO. In addition these phosphides show bifunctional
catalytic properties (metallic sites for hydrogenation and acid sites for cracking, methyl transfer reaction, dehydration and
isomerization).

Biography
Antonia Infantes-Molina is a Senior researcher at the University of Malaga. Chemical Engineer (2002) and Ph in Science (2006-University of Malaga) has developed
its research line in the synthesis and characterization of nanomaterials and nanocatalysts as well as their use for environmental applications. After her PhD, she has
studied adsorbent materials in collaboration with Pesquisa em Separações por Adsorção, Universidade Federal do Ceará (Brasil); catalytic systems for clean fuels
production in the Institute of Catalysis and Petroleochemistry (ICP-CSIC) in Madrid (Spain) and NOx catalytic removal frommobile sources and catalytic processes for CO
2
transformation in the Laboratory of Catalysis and Catalytic Processes group at Politecnico di Milano. Her current research includes catalytic hydrodeoxygenation as well
as waste valorization: new catalytic formulations and new applications for ashes derived from biomass treatment.
