摘要：

Role of nitrogen-containing organic compounds produced during the plasma process on the subsequent Of C2H4-SCR of NOx over Ag/gamma-Al2O3 catalyst at 523 K was studied in a two-stage plasma-facilitated catalysis system. Results showed that nitrogen-containing organic compounds (methyl nitrate, ethyl nitrate, nitro methyl) produced in the plasma reactor can improve the subsequent catalytic performance at lower temperature besides NO2 and aldehyde; more the amounts of nitrogen-containing organic compounds produced after plasma pretreatment, more the amounts of N-2 produced in the subsequent catalysis process, and N-2 selectivity leveled at about 82%.
