Synthesis and Characterization of MgO/MCM-22 as Catalytic Support Using the Impregnation Technique

Abstract:

MCM-22 is a microporous molecular sieve with a system of sinusoidal three-dimensional channels that do not interconnect themselves, which presents good adsorption capacity and high acidity. Thus, this study aims to evaluate the chemical and structural properties of the catalyst MgO/MCM-22 using wet impregnation method. The synthesis of the zeolite was performed using the static hydrothermal method. Through the XRD patterns, it was possible to observe that the metal incorporation process did not cause structural changes, as well as the analysis showed small peaks related to the magnesium oxide in the structure. The micrographs presented a spherical morphology with depression in the central region. FTIR spectra showed the typical peaks of metal with little differences in the typical peaks of MCM-22.
