摘要/Abstract

摘要： Mechanism analysis on simultaneous oxidation of NO and SO2 with additives was presented and
numerical simulation was developed to investigate the performances of three additives on
oxidation of NO and SO2. The simulation result showed that reaction temperature, residence
time, additive dose and NO concentration influence the oxidation process significantly.
There exists an optimum reaction condition for each additive. n-C4H10 has the strongest
ability to oxidize NO and SO2.
