| Abstract: | An oil drop granulation process was developed to prepare porous meso-structured gamma (??) alumina (Al2O3) granules. The ??-Al2O3 granules prepared were 2?mm diameter spherical particles with low sphericity factor (0.02?±?0.01). The XRD results validated that the synthesized granule possesses crystallinity of ??-Al2O3 phase. The N2 adsorption?Cdesorption isotherm and BJH pore size distribution of the synthesized granule elucidated the existence of mesoporous characteristic with unimodal pore in the mesopore region. The synthesized and characterized granules can be used as a potential support for catalyst in either moving or fluidized bed reactor. |
