CLAURE ZEBALLOS, Mauricio; PARDO TARIFA, Fátima L.; LOPEZ N, Luis G.  e  CABRERA M, Saúl. Synthesis of silicoaluminate mesoporous support by the atrano route, morphological and acidity properties of the mesocellular foam, MCF, for cobalt catalysts design. Rev. Bol. Quim [online]. 2022, vol.39, n.3, pp.15-30. ISSN 0250-5460.  https://doi.org/10.34098/2078-3949.39.3.2.

The synthesis of silicoalumina mesoporous supports was carried out by the atran route. The supports obtained showed high homogeneity in the aluminum dispersion, a large surface area and a narrow pore size distribution. The synthesized mesoporous mesocellular foam (MCF) supports contain 5%, 10% and 15% Al2O3 in the SiO2 matrix. 12% cobalt was added to these mesostructured supports by the incipient wetness impregnation method. These materials were characterized by Nitrogen adsorption (BET-BJH), Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), Temperature Programmed Reduction of H2 (TPR), and Temperature Programmed Desorption of NH3. (TPD). According to the structural properties of these catalysts, a promising application in Fischer-Tropsch (FTS) syntheses is identified.
