Non-Thermal Plasma Incorporated with Cu-Mn/γ-Al2O3 for Mixed Benzene Series VOCs’ Degradation

نویسندگان

چکیده

In this work, a coaxial dielectric barrier discharge (DBD) reactor was constructed to degrade the mixture of toluene and o-xylene, two typical benzene series. The Cu-MnO2/γ-Al2O3 series catalysts prepared by redox impregnation methods were filled into plasma device VOCs synergistically explore degradation effect. experimental results showed that introduction Cu-doped MnO2 catalyst significantly improved pollutants’ removal efficiency CO2 selectivity, greatly inhibited formation by-products. Among them, Cu0.15Mn/γ-Al2O3 highest (toluene 100% o-xylene 100%), best selectivity (92.73%). XRD, BET, XPS SEM confirmed synergistic effect between Cu Mn in Cu-Mn solid solution could promote amount reducibility surface active oxygen species, which catalytic performance. Finally, decomposition pathways NTP system speculated according detected organic matter. This work provides theoretical basis for application DBD-catalyzed hybrid VOCs.

VOCs degradation with non-thermal plasma and Ag-MnOx catalysis

Non-thermal plasma (NTP) is effective for degradation of aromatic molecules, achieving complete mineralization, however, is difficult. In contrast, thermal catalysis may be very effective toward achieving complete mineralization at high temperatures. Its drawbacks at a low processing temperature are undesirable intermediate byproducts production. By integrating dielectric barrier discharge with...

Non-thermal Plasma Processing for Dilute VOCs Decomposition Combined with the Catalyst

0BAbstract: Atmospheric pressure non-thermal plasma process combined with the new catalyst for volatile organic compounds, especially dilute tricholorethylene (TCE) in synthesized dry air is discussed. TCE decomposition efficiency is very good and more than 95% of TCE is easily decomposed at SED (specific energy density) of 18 Joule/litter which is practical value. However, more discharge energ...

Abatement of VOCs Using Packed Bed Non-Thermal Plasma Reactors: A Review

Non thermal plasma (NTP) reactors packed with non-catalytic or catalytic packing material have been widely used for the abatement of volatile organic compounds such as toluene, benzene, etc. Packed bed reactors are single stage reactors where the packing material is placed directly in the plasma discharge region. The presence of packing material can alter the physical (such as discharge charact...

Non-thermal Plasma Technology for Degradation of Organic Compounds in Wastewater Control: a Critical Review

Non-thermal plasma is an emerging technique in environmental pollution control technology, produced by the high-voltage discharge processes and therefore a large amount of high energy electrons and active species are generated. The degradation of difficult-degraded organic pollutions will be greatly enhanced by the active species generated from non-thermal plasma process. However, research on n...
