Biohydrogen production by gas phase reforming of glycerine and ethanol mixtures

► Bioalcohol mixtures conversion mainly resulted in gaseous products at 773 K. ► Important quantities of intermediate liquid products were detected at 723 K and 673 K. ► La2O3 on Ni/Al2O3 catalyst improved Ni dispersion, resulting in higher H2 yield. ► CeO2 on Pt/Al2O3 catalyst enhanced reducibility and Pt surface exposure.
