Hydrogen production by iso-octane steam reforming over Cu catalysts supported on rare earth oxides (REOs)

Why is it important?

Steam reforming of iso-octane over Cu supported on rare earth oxides is examined. H2 yield follows the sequence: CeO2 ≫ Nd2O3 > Gd2O3 > Sm2O3 ≈ Pr6O11 ≈ La2O3. H2 yields up to ∼55% are obtained at the expense of CH4 and higher hydrocarbons. Close correlation between redox/textural properties and reforming activity is revealed. Severe deactivation due to carbon deposition and catalyst sintering is observed.
