Hidrogeno-ekoizpena bio-oilaren erreformatze katalitikoaren bidez

Abstract

The growing demand of H₂ for its use as petrochemical raw material and clean fuel has boosted the development of processes for its production from alternative sources to oil, among which biomass has received special attention due to its availability and renewable nature. There is an increasing interest in the development of indirect routes for H₂ production from biomass, via steam reforming of biomass-derived oxygenated compounds. Indirect pathways to obtain hydrogen from biomass, such as the steam reforming of oxygenates derived from biomass, are these days in the spotlight. Among them, the so called bio-oil deserves special attention, due to its economic viability. Actually, delocalized production of bio-oil in biomass production plants allows for its subsequent transportation to centralized units for its further valorization. However, problems caused by the pyrolytic lignin produced during this process need to be also considered, specially, the solid residue deposited on both the catalyst and the reaction setup when bio-oil evaporates. Scale up technology is deemed necessary in order to solve this drawback. Moreover, the development of an active, selective and stable catalyst is of the utmost importance towards achieving full viability of the process. In this piece of work, we aim at giving an overview on the main bio-oil reforming strategies in literature, with special emphasis on the results from our research group.
