SYNTHESIS OF SILICOALUMINATE MESOPOROUS SUPPORT BY THE ATRANO ROUTE, MORPHOLOGICAL AND ACIDITY PROPERTIES OF THE MESOCELLULAR FOAM, MCF, FOR COBALT CATALYSTS DESIGN

Abstract

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 FischerTropsch (FTS) syntheses is identified.
