Abstract
Molecular sieves of MCM-41 impregnated with MgO, MoO3, and Mo2C synthesized using a wet impregnation method. The compounds developed herein, were characterized by means of XRD, SEM-EDS and FT-IR techniques. The production capacity of acetaldehyde from ethanol was analyzed by catalytic processes employing as-synthesized MCM-41. The obtained results show that the changes in crystallinity of MCM-41 were due to the impregnation of oxides, which generate damage to the structure of MCM-41. However, the characteristics of the compounds are favorable, allowing them to be used as heterogeneous catalyst material due to the similarity of the characteristics between MCM-41 with and without of Mg and Mo oxides. The catalysis tests show the influence between the type of catalyst used and the temperature applied to the production process of acetaldehyde from ethanol, obtaining the best results in the samples impregnated with Mo2C at 250 °C, with a production percentage of acetaldehyde of 80.7% and 77.9% for the catalysts impregnated with 0.5% and 2.0% Mg and 3.0% Mo carbide, respectively.
