Catalytic removal of nitrogen oxides for the lean-burn automobile exhaust

  • 摘要: 用溶胶-凝胶混合法制备了Al2O3,Ag/Al2O3,Sn/Al2O3,Ga/Al2O3,Co/Al2O3和Pt/Al2O3等催化剂.在相同实验条件下,比较了C3H6在这些催化剂上还原NO的活性,并考察了反应条件对C3H6和CH3OH在Ag/Al2O3上还原NO性能的影响.结果表明,Ag/Al2O3的还原NO活性优于其它催化剂.H2O对Ag/Al2O3催化剂的NO还原具有可逆抑制作用,SO2降低C3H6在Ag/Al2O3上还原NO的活性,但会显著提高CH3OH还原NO的活性.
