“…This trend matches with the report by Q. H. Trnh and colleagues [28]. Accordingly, the adsorption amount per 10 g Agzeolite is 3.37 × 10 −2 g (i.e., 3.37 × 10 −3 g per 1 g Agzeolite pellets).…”

“…These results demonstrate that the ethylene adsorption amount significantly increase by loading Ag nanoparticles on zeolite. This trend matches with the report by Q. H. Trnh and colleagues [28]. Figure 8 shows the outlet ethylene concentration change against the input energy density when Ag-zeolite, zeolite, and glass were, respectively, used as pellets.…”

Ethylene gas was decomposed using packed-bed type dielectric barrier discharge (PBDBD) plasma reactor to keep freshness of fruits. The ethylene gas was diluted with gas mixture of nitrogen, oxygen, and carbon dioxide as simulated gas in the transportation container. The PBDBD plasma was generated by a pulse switching power supply, which consisted of MOS-FET switching devices, capacitors, and pulse transformers. The Ag nanoparticle-loaded zeolite as catalyst has high activity and good performance for reduction of ozone and oxidizing carbon monoxide at room temperature. The Ag nanoparticle-loaded zeolite pellets enhanced ethylene removal efficiency and reduced ozone and carbon monoxide produced by the plasma treatment. It was confirmed that the carbon monoxide in the gas simulated dry air composition was oxidized using Ag nanoparticle-loaded zeolite with plasma treatment. C⃝ 2017 Wiley Periodicals, Inc.

“…The ethylene adsorption capacity of zeolites is enhanced by the presence Ag cation due to the strong interaction between the charge compensating cation in the zeolite framework and the double bond of ethylene [51,[90][91][92][93][94]. When compared to bare 13X zeolite, Ag/13X zeolite exhibited higher ethylene adsorption capacity because of the π-complexation between Ag(I) species and ethylene double bond [93,95,96] in addition to the interaction between the adsorbed oxygen and ethylene. The metals with empty s-orbital and available electrons in the d-orbital could form π-complexation bonding.…”

“…Also, the emission of by-products such as O 3 and CH 4 was suppressed by the Ag-Fe/13X zeolite when compared with other bimetallic 13X-zeolite. Thus, the affinity of the metal oxide loaded zeolite towards the adsorbed VOCs plays an important role in the desorption and oxidation of the desorbed VOCs [95] as the rate of oxidation reaction is higher in the gaseous phase [93]. The increase in the amount of adsorbent from 4.8 g (HiSiv 3000) to 8 g (HiSiv3000 = 2.5 g and HiSiv1000 = 5.5 g), decreases the conversion efficiency of p-xylene due to the fact that the conversion is faster in gaseous phase and the increase in the amount of adsorbent reduces the desorption of p-xylene [47], and thus the reduced conversion efficiency.…”

Non-thermal plasma technique can be easily integrated with catalysis and adsorption for environmental applications such as volatile organic compound (VOC) abatement to overcome the shortcomings of individual techniques. This review attempts to give an overview of the literature about the application of zeolite as adsorbent and catalyst in combination with non-thermal plasma for VOC abatement in flue gas. The superior surface properties of zeolites in combination with its excellent catalytic properties obtained by metal loading make it an ideal packing material for adsorption plasma catalytic removal of VOCs. This work highlights the use of zeolites for cyclic adsorption plasma catalysis in order to reduce the energy cost to decompose per VOC molecule and to regenerate zeolites via plasma.

Some of fresh produces emit ethylene gas, one of plant hormones, which promotes the aging for themselves and accelerates senescence of other agricultural produce. In transportation of some kinds of agricultural produce, reducing ethylene gas in the transportation container is important for keeping freshness of fruits and vegetables. In this study, ethylene gas was decomposed using a dielectric barrier discharge (DBD) plasma reactor. The ethylene gas was diluted with the gas mixture of nitrogen, oxygen and carbon dioxide as simulated gas in the transportation container. The DBD plasma was generated by a pulse switching power supply consisted of MOS-FET switching devices, capacitors and pulse transformers. The mixture gas was contained harmful by-products, ozone and carbon monoxide after DBD plasma treatment. An Ag nanoparticle-loaded zeolite was set in the catalytic reactor to remove the by-products. The catalytic reactions reduced the by-products produced by the plasma treatment. It was confirmed that carbon monoxide diluted with simulated dry air was oxidized to carbon dioxide by the catalyst and DBD plasma.
