“…Dielectrics packed in the discharge zone cause the increase of mean electron energy and the decrease of electron density at an identical discharge power, that is, cause the decrease of the amount of microdischarges [20,30]. Thus the recombination of O radicals is promoted in a dielectric packed reactor, inhibiting the conversion of CO.…”

“…Suib et al [16][17][18] have conducted a series of study on CO 2 decomposition in AC glow discharge reactors, and investigated the various influence factors such as metal catalysts, discharge parameters and additional gases. Li et al [19][20][21][22] have used Ca x Sr (1-x) TiO 3 as barrier materials in the decomposition of CO 2 in dielectric barrier discharge (DBD) plasma, and investigated the relation between the microdischarges and the permittivity of the barrier materials. It was found that Ca 0.8 Sr 0.2 TiO 3 with 0.5 wt% Li 2 Si 2 O 5 as dielectric barrier is optimum to obtain a steady discharge state and an efficient decomposition of CO 2 .…”

The decomposition of CO 2 in a dielectric packed-bed plasma reactor has been studied. It was found that the dielectric properties and morphology of packing dielectric pellets play important roles in the reaction due to their influence on the electron energy distribution in the plasma. The acid-base properties of the packing materials also affect the reaction through the chemisorption of CO 2 on basic sites of the materials. Heterogeneous reactions on the solid surfaces of the dielectric materials also play a role in the reaction, which was also confirmed through the investigation of the influence of the discharge length on the reaction. The reverse reaction of CO 2 decomposition, the oxidation of CO, was also investigated to further understand the role of dielectric materials in the plasma and their effect on plasma reactions. Both the decomposition of CO 2 and the oxidation of CO in nonpacked or dielectric packed reactors are first-ordered.

“…A dielectric barrier with a high permittivity is highly desirable in order to generate plasma possessing high reactivity. R. Li et al [12] reported that the ratio of CO 2 decomposition using Ca 0.7 Sr 0.3 TiO 3 was much greater than commercial alumina and silica glass barriers, so as to obtain a conclusion that the CO 2 decomposition was proportional to the permittivity of the dielectric barrier materials. Analogously, filling suitable dielectric materials shaped in appropriate geometries through discharge volume may be an effective approach to enhance the destruction efficiency for VOCs.…”

a b s t r a c tDischarge characteristics and abatement of volatile organic compounds using plasma reactor packed with ceramic Raschig rings were investigated. It was found that the gap equivalent capacitance decreased with increasing voltage while the dielectric barrier equivalent capacitance increased initially and stabilized at about 700 pF. Compared with empty reactor, toluene removal was significantly enhanced by ceramic Raschig rings, 97% against 48%. With respect to the energy yield in the presence of padding, the efficiency was remarkably improved up to 10 g/kWh, which was 2 times higher than that of 5 g/kWh in the absence of padding with removal ratio exceeding 50%.Crown

“…In these years, some new technologies, such as biologic process, photocatalysis process, and plasma technology, were paid more and more attention (Ogata, 1999;Futamura et al, 2004;Li et al, 1998;Magureanu, 2007;Urashima et al, 2000;Zhu et al, 2007a). In particular, non-thermal plasma has attracted much attention as an method for VOCs control for two decades due to its unique properties such as quick response at ambient temperature, achievement of high electron energies within short residence times, system compactness, and easy operations (Muhamad, 2000;Li et al, 2006). In order to improve the energy efficiency of the VOCs decomposition process by the plasma, the cooperation with catalyst has been tested by some researchers (Einaga et al, 2001;Guo et al, 2006;Jim, 2008;Krawczyk, 2001;Magureanu et al, 2007a and b;Ogata et al, 2003;Wallis et al, 2007;Li et al, 2007;Zhu et al, 2007b).…”

Plasma technology has some shortcomings, such as higher energy consumption and byproducts produced in the reaction process. However non-thermal plasma associated with catalyst can resolve these problems. Therefore this kind of technology was paied more and more attention to treat waste gas. A hybrid system comprising a non-thermal plasma reactor and nanometer titanium dioxide catalyst was used for benzene removal in the air. The paper described the synergistic effect of ozone and photocatalyst in the plasma reactor. Except of electric field strength, humidity and flow velocity, the synergistic behavior of ozone and photocatalyst was tested. The removal efficiency of benzene reaches nearly 99% when benzene concentration is 600 mg/m 3 , and the removal efficiency of benzene also reaches above 90% when benzene concentration is 1500 mg/m 3 . The plasma reactor packed with photocatalyst shows a better selectivity of carbon dioxide than that without photocatalyst. The final products is mostly carbon dioxide, water and a small quantity of carbon monoxide.
