Emission reduction characteristics of NO_x catalyst with simulated lean burn methanol fuel vehicles exhaust gas

摘要

Characteristics of methanol reduction and formaldehyde formation with NO_x catalyst (Co_(-y) Al_2O_3 and Sn_(-y) Al_2O_3) have been investigated in comparison with oxidation catalyst (Pt_(-y) Al_2O_3). Pure y-Al_2O_3 was also used additionally. Laboratory experiments were conducted by using above catalysts in oxygen rich atmosphere considering lean burn methanol engines or diesel type methanol engines. Catalyst temperature and concentration of NO in the simulated exhaust gas were selected as experimental parameters.
