Trabajo final elaborado por mi amigo brasileño Caio Ishikura en el marco del Diploma de Especialización en Tecnologías de Hidrógeno y Pilas de Combustible dictado por el Centro de Investigación de Recursos y Consumos Energéticos de la Universidad de Zaragoza.

Se trata de producción de hidrógeno por medio de reformado de vapor de materias-primas o recursos renovables.

 Título: Steam Reforming of Renewable Feedstock’s for the Production of Hydrogen

Abstract: In view of the continuing importance of the biofuels as a source of hydrogen, there is a need for a comprehensive review on this topic. The importance of process engineering related aspects is evident and these need to be discussed at length.

This work is aimed at fulfilling this need. It reviews the available literature on catalytic steam reforming of biofuels. The key research issue for this concept is to demonstrate that bio-fuels can be efficiently steam reformed. All published information on this topic is analyzed and presented in a coherent manner. The role of the catalyst composition and the process conditions in determining product distribution is elucidated. The possible reaction pathways and thermodynamic considerations have also been discussed. The strategy can be applied to bio-oils, residual fractions derived from industrial operations and from ethanol production. Effluents

from other biomass processing technologies such as transesterification of vegetable oils can also be attractive feedstocks for the production of hydrogen.

The focus is on catalytic steam reforming of different biomass-derived liquids. It is expected that this will provide an insight into the possibilities of steam reforming of biofuels to produce hydrogen.
