The performance of 1,1,1,2-tetrafluoroethane or HFC-134a decomposition and the formation of byproducts in a dielectric barrier discharge plasma reactor were studied with different packing systems such as a-Al 2 O 3 (porous and nonporous), c-Al 2 O 3 (porous) and ZrO 2 (nonporous). Experimental variables such as reactor temperature, initial HFC-134a concentration and oxygen levels were chosen for the performance analysis. Among the packing systems, the porous c-Al 2 O 3 and a-Al 2 O 3 decomposed HFC-134a much more effectively than the nonporous a-Al 2 O 3 and ZrO 2 . The combination of the plasma with the porous cAl 2 O 3 was found to cover a wide range of initial concentration. The decomposition efficiency tended to increase with the addition of oxygen up to 2 %, but further increase in the oxygen led to a decrease. As well as carbon oxides (CO 2 and CO), significant amounts of unwanted byproducts such as COF 2 and CF 4 were also identified in the effluent gas with the nonporous a-Al 2 O 3 and ZrO 2 . On the contrary, with the porous c-Al 2 O 3 and a-Al 2 O 3 , such unwanted byproducts were considerably suppressed, enhancing the formation of CO 2 and CO.

“…Quartz or glass tubes are widely used as dielectric barrier in the packed bed reactors used for the decomposition of VOCs. The high voltage (or discharge) electrode can be made of stainless steel rod [47][48][49][50][51], stainless steel wire [52,53], stainless steel spring [54,55], stainless steel bolt [56,57], aluminum rod [58], copper rod [59], molybdenum rod [60] or tungsten wire [43,[61][62][63]. The surface area and geometry of the inner electrode plays an important role in the discharge characteristics of the plasma reactor.…”

“…As shown in Figure 2, the presence of packing materials in the discharge region maximizes the number of micro streamers and thus producing more high energy electrons [18]. These energetic electrons produce reactive intermediates resulting in increased VOC removal efficiency when compared to the unpacked reactors [57,73,74]. Surface discharges produced along the surface of the packing material may distribute the plasma more evenly and intensively throughout the reactor [75] and the catalytic reactions occur on the surface of the packing material.…”

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

et al. 2017

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 characteristics, power consumption, etc.) and chemical characteristics (oxidation and destruction pathway, formation of by-products, etc.) of the reactor. Thus, packed bed reactors can overcome the disadvantages of NTP reactors for abatement of volatile organic compounds (VOCs) such as lower energy efficiency and formation of unwanted toxic by-products. This paper aims at reviewing the effect of different packing materials on the abatement of different aliphatic, aromatic and chlorinated volatile organic compounds.

“…Several studies on laboratory applications of the DBD for VOC removal focused on single VOCs (Magureanu et al, 2007;Gandhi et al, 2013;Quoc et al, 2011;Ragazzi et al, 2014), whilst real emissions from industrial or waste treatment plants include a large variety of compounds. However, the number of studies focusing on mixtures of VOCs is still limited.…”
