摘要:
采用介质阻挡放电(DBD)低温N2、O2等离子体技术对黏胶基活性炭纤维(V-ACF)进行表面改性,运用BET、SEM、NH3-TPD和 FT-IR对催化剂进行表征,并对催化剂低温选择性催化还原(SCR)NO性能进行了研究。结果表明,N2、O2等离子体最佳改性时间分别为5 min与10 min,最佳反应温度为100 ℃,低温等离子体改性能明显提高ACF上NO转化率,且N2等离子体改性ACF催化效率高于O2等离子体改性ACF。
Abstract:
Viscose-activated carbon fiber(V-ACF)modified by low-temperature N2 and O2 plasma with dielectric barrier discharge(DBD)was studied for low-temperature selective catalytic reduction(SCR)of NO. Structure of the plasma modified V-ACF was characterized by BET,SEM,NH3-TPD and FT-IR. Experimental results showed that the optimal surface modification time was 5 and 10 minutes for N2 and O2 plasma,respectively. The optimal reaction temperature was 100℃. Surface modification of V-ACF by low-temperature plasma technology could greatly improve the NO removal rate. V-ACF modified by N2 plasma showed higher NO removal rate than that modified by O2 plasma.
