【Abstract】 Studied on preparation of laden catalysts for decomposing ozone tail gas by using dip method.The experiment was performed in a fixed bed reactor,and the catalytic activities are investigated.The experimental results showed that the catalysts with activated carbon had the best catalytic activity for decomposing ozone tail gas.Removal efficiency of ozone can reach about 97.2% when reacting time was controlled in 0.036s and initial ozone concentration of 2.5g/m 3.One gram the catalyst could reach 98h operation and completely decompose 8.8g ozone at the same initial ozone concentration and the residence time in reactor of 0.1s.The experimental result also indicated that humidity of reaction system influenced catalytic activity considerably.更多还原
