| Abstract: | The research status and progress both at domestic and abroad in view of the problem of N2O abatement and recycling have been introduced in this paper. The research related to N2O separation and purification potentially applied in medical and electronic manufacturing and aromatics oxidation to phenol is analyzed in detail. The achievements and research status on N2O abatement techniques such as thermal and catalytic decomposition are summarized. It is pointed out that catalytic decomposition is a feasible technique about N2O emission reduction. The catalyst with high activity and good resistance to O2 and impurities such as water vapor and sulphur oxide in exhaust gas is still a research hotspot in this field both at domestic and abroad. |
