Resumen:
The influence of the alumina layer nature which acts as the support on the preparation of structured catalysts
and on the catalytic performance in VOC combustion was studied. Anodized aluminum and a ferritic alloy
covered with colloidal alumina (Nyacol) and è-ä-Al2O3 were the materials used to prepare the monolith
catalysts. The impregnation was performed in one and two stages using two different concentrations of
manganese acetate solutions. The catalytic properties of these catalysts were evaluated in ethanol, ethyl acetate,
and toluene combustion. The most active catalysts in the combustion of the three molecules were those prepared
using a è-ä-Al2O3 as a support. The low activity of aluminum monoliths anodized with H2SO4 is due to the
presence of SO4
2- ions which act as catalyst poison. The anodization with H2C2O4 is a preferable method to
prepare MnOx monolithic catalysts.è-ä-Al2O3 were the materials used to prepare the monolith
