摘要：减排N_2O对控制地球温室效应和保护人类健康具有重要的意义。综述了有关分离纯化N_2O的技术及N_2O回收利用于芳烃氧化制苯酚的研究进展,介绍了N_2O的热分解及催化分解等减排技术的研究成果。指出:采用N_2O直接氧化芳烃制苯酚技术需要解决的技术关键是开发高选择性的催化剂;催化分解是目前可行的N_2O减排技术,而制备高活性且抗O_2、水蒸气及硫化物干扰的催化剂是今后的研究热点。
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.
