Perovskite modified catalysts with improved coke resistance for steam reforming of glycerol to renewable hydrogen fuel

Catalytic steam reforming of renewable feedstock to renewable energy or chemicals always goes with intense coking activities that produce carbonaceous products leading to low performance and eventual catalyst deactivation. A supported metal catalyst such as Ni/Al2O3 is known to catalyse gasification and decomposition of biomass feedstock largely for renewable fuel production with promising results. Catalyst deactivation from high carbon deposition, agglomeration, and phase transformations resulting in rapid deactivation are some of the issues identified with the use of the catalyst. In this work, improvement on the coke resistance and catalytic properties of the Ni/Al2O3 catalyst is sought via the use of a thermally stable and coke-resistant perovskite La0.75Sr0.25Cr0.5Mn0.5O3-δ (LSCM) as catalyst promoter/modifier and involving Zirconia-doped Ceria (Ce-Zr) as alternative support in steam reforming of pure and by-product glycerol. The stabilizing influence of the LSCM on the Ni catalyst..., The dataset is from material synthesis, characterisation, and catalyst testing., Origin software
