Structured catalysts for biofuels transformation into syngas with active components based on perovskite and spinel oxides supported on Mg-doped alumina

For structured catalysts of biofuels transformation into syngas inexpensive and stable to sintering active components based upon Mg-doped gamma-alumina with supported LaNi0.9Ru0.1O3 perovskite or MnCr2O4 spinel promoted by Ru + Ni were developed. Characterization of the surface features, reactivity, catalytic activity and routes of ethanol transformation on these catalysts demonstrated that suppression of support acidity, strong interaction of Ru-Ni alloy nanoparticles with manganese chromite layers on support and a high redox ability provide a high yield of syngas and stability to coking. The most promising active component (2 wt% Ni + 2 wt% Ru)/MnCr2O4/10 wt% MgO gamma-Al2O3 supported on microchannel heat-conducting CrAlO cermet plates demonstrated a high performance and stability to coking in the autothermal reforming of such reactive fuels as glycerol, anisol and turpentine, oil.
