Plasma driven catalysis technology was applied for NO removal from flue gas over HZSM-5 zeolite. The A-N2-D-N2 (Adsorption-N2 flushing-non-thermal plasma(NTP) decomposition-N2 flushing) system was found to be effective for both NO removal and energy consumption. HZSM-5 exhibited excellent performance in adsorbing NO from the low-concentration gas emissions and the adsorption capacity could be well recovered in the subsequent non-thermal plasma treatment process. In the adsorption-plasma process, the N2 purging after NO adsorption stage significantly improved the decomposition efficiency of adsorbed NOx. The A-N2-D-N2 system exhibited excellent recyclability and sustainable capability with about 90% NO removal efficiency after six cycles.

通过循环吸附-等离子工艺从HZSM-5上去除烟道气中的NO

等离子体驱动的催化技术被应用于在HZSM-5沸石上去除烟道气中的NO。发现AN 2 -DN 2(吸附-N 2冲洗-非热等离子体(NTP)分解-N 2冲洗)系统对于去除NO和消耗能量均有效。HZSM-5在从低浓度气体排放中吸附NO方面表现出出色的性能,并且在随后的非热等离子体处理过程中可以很好地恢复吸附能力。在吸附等离子过程中,NO吸附阶段之后的N 2吹扫显着提高了吸附的NOx的分解效率。该AN 2 〜DN 2 该系统具有出色的可回收性和可持续能力,六个循环后的脱氮效率约为90%。
