【Abstract】 Oxidation activity of the CuO/r-Al2O3 catalysts for n-Hexane (n-C6H14) and effect of CuO contents for activity have been studied. The addition of CeO2 over CuO/r-Al2O3 catalysts for carbon monoxide(CO) oxidation were investigated by means of the CO-flow method between the condition of lean O2 (O21.8%,CO3.0%) and abundant O2 (029.0%, CO 3.0%). Experimental results showed that the addition of CeO2 could improve oxidation activity of CuO/r-Al2O3 catalysts at the lean O2 state. The test of engine industrial condition for catalysts also indicated that this catalysts had excellent oxidation ability for CO and HC.更多还原
