Glycerol steam reforming for hydrogen production in Pd/Al2O3 and Pd/CeO2/Al2O3 catalysts

Abstract

Pd/Al₂O₃ and Pd/CeO₂/Al₂O₃ catalysts were prepared and tested in glycerol steam reforming. The catalytic tests were carried out in a fixed bed reactor for continuous flow using glycerol solution 10 vol.% in water diluted in helium. The composition of the mixture and the reaction selectivity in H₂ was evaluated in these catalysts according to temperature and reaction time on stream, and the Pd/CeO₂/Al₂O₃ catalyst showed the highest H₂ selectivity and stability throughout the operating range study presented this work.
