Abstract: The catalysts mLnNi0.9Ru0.1О3/nMg-γ-Al2O3 (Ln = La, Pr, m=10-20%wt, n=6-15%wt) have been prepared by impregnation, characterized by XRD, BET, TEM with EDX, UV-vis, XPS, TPR-H2, FTIRS of CO test molecule and studied in ethanol steam reforming as fractions and layers on structured ceramic and Ni-Al alloy substrates. The influence of Ln nature and Mg concentration on the structural and redox properties of the catalysts have been elucidated. High activity and coking stability of catalysts are provided by a high dispersion of metallic Ni and Ni-Ru alloy due to strong interaction with LnOx/MgO/γ-Al2O3 support and suppressing support acidity by Mg/Ln cations. The optimal catalyst supported on Ni-Al foam substrate shows high and stable performance in a realistic reaction mixture during 50 hours.
