Bio-ethanol catalytic steam reforming over supported metal catalysts

SSCI-VIDE+CARE+CDSInternational audienceConsidering both the influence of the nature of the metal (Rh, Pt, Ni, Cu, Zn, Fe) and the role of the support (gamma-Al2O3, 12%CeO2-Al2O3, CeO2, Ce0.63Zr0.37O2), CO2 is presented as a primary product in the bio-ethanol steam-reforming catalytic reaction (SRR) over some supported metal catalysts. Based on this unexpected observation, a new strategy for maximizing the hydrogen production and minimizing the CO formation is proposed. Any highly selective catalytic formulation should be free of any promoter in the water gas shift reaction (WGSR) which tends to equilibrate the SRR gas towards higher CO concentrations.

Catalytic steam reforming: Use for on-board hydrogen production from hydrocarbons or alcohols

SSCI-VIDE+CARE+CDSInternational audienceTo identify the challenges in the development of electrical vehicles, literature was rapidly reviewed. Research on hydrogen production processes suitable for fuel cell applications is a major challenge. Catalytic steam reforming of hydrocarbons as well as alcohol is a very promising route. The choice of ethanol and supported rhodium catalysts will be justified in the light of ethanol physico-chemical properties, reaction mechanism, cerium-based oxides characteristics and the specifications imposed by fuel cell applications
