Alumina (γ-Al2O3), Silica (SiO2) and Titania (TiO2) have been widely used as adsorbents or catalyst/catalyst supports for dehydrogenation and desulfurization because of their high surface area, high thermal and chemical stability. In this study, γ-Al2O3, SiO2, TiO2 particles were synthesized by spray pyrolysis combined with sol-gel process. The spray pyrolysis method has advantages of synthesizing spherical nano- or micron-sized particles in one step and controlling the size and morphology of the product particles. Also, mass production is possible with this method as it tis a continuous reaction process. In order to control specific surface area and pore structures, the particles were prepared by adding CTAB as a template. The product particles were analyzed by BET, XRD and FE-SEM. |
