The cylindrical-type porous pellets of copper-manganese oxide mixed with light-weight inorganic fillers were prepared by extrusion method and the gas removal activity depending on the various process variables was systematically compared. In addition, the mechanical properties including pellet hardness, density, and physical properties such as porosity, surface area, etc, were also investigated. It was found that the newly prepared oxide catalyst-loaded pellet type granules exhibited excellent mechanical and physico-chemical properties; high pellet hardness(＞4.0 kg/cm2), very low apparent density (＜0.7 g/cm3), large pore volume (＞1.0 cm3/g) and specific surface area (＞500 m2/g), respectively. Furthermore they showed excellent CO removal activity at room temperature. |
