NO直接分解催化剂研究

Study on the Catalysts for NO Direct Decomposition

在Cu_ZSM_5和Co_ZSM_5系列催化剂上 ,研究了NO直接分解时的催化性能 .实验结果表明 ,Cu_ZSM_5系列催化剂在高温、低W /F条件下具有较高的活性 ;而Co_ZSM_5系列催化剂活性较高 ,并且具有较好的稳定性 .在反应温度为 773K ,W /F为1g·s·cm- 3,反应时间达 30h以上时 ,NO的转化率大于 4 0 % .

Catalysts Cu_ZSM_5 and Co_ZSM_5 were prepared and used for the direct decomposition of NO. The experimental results showed that Co_ZSM_5 catalyst had the best catalytic properity under the condition of high temperature and low W/F value, but Cu_ZSM_5 showed high activity and good stability. On the condition of 773 K and 1 g·s·cm -3 of W/F value, the conversion of NO was still higher than 40% after 30 h of reaction.
