Interaction of nonthermal plasma and Ag-supported zeolite

Abstract:
In this work, we report the interaction of nonthermal plasma andAg-supported zeolite for the effective removal of volatile organic compounds(VOCs). The Si/Al ratio affected the status of Ag, which in turn leaded to adifferent catalytic performance. The higher the Si/Al ratio, the higher the metallic
Ag and the larger the reduction in relative resistivity. The propagation of surface
streamer became weak as the Si/Al ratio increased. These electro- and physicalproperties of zeolites were found to be closely linked with the catalytic activity ofAg/zeolite. The direct interaction of surface plasma with the surface of zeolite
was also evidenced by the electron spin resonance (ESR) spectrometer. The
possible mechanism on these observation will be discussed.

Experiment and Simulation of CO2 Decomposition Using
Dielectric Barrier Discharge○Yota YOSHIDA, Naoki SHIRAI, Satoshi UCHIDA, Fumiyoshi TOCHIKUBOTokyo Metropolitan University,

Abstract:
We studied CO2 decomposition using dielectric barrier discharge andpacked bed discharge with coaxial electrode configuration at atmosphericpressure aiming the conversion into methanol. To discuss the possibility ofconversion of CO2 into methanol, the reaction pathway was investigated by thereaction simulation using CHEMKIN. The simulation results suggest that therate-limiting reaction is the hydrogenation of CH2O.

Effect of Reverse Water-Gas Shift and Methanation
Reactions on Plasma-assisted Dry Methane Reforming○Seigo KAMESHIMA*, Keishiro TAMURA*, Sampson MOORE**, Tomohiro

Abstract:
This study focuses on the reaction mechanism of low temperatureplasma-assisted dry methane reforming (DMR). At low temperature (< 500 °C),
CO2 is reduced by H2 catalytically, which may produce either CO (CO2 + H2 =CO + H2O; reverse water-gas shift reaction) or CH4 (CO2 + 4H2 = CH4 + 2H2O;
methanation). We found that the RWGS is dominant reaction pathway, while
CH4 production has negligible effect. Plasma-catalyst hybrid reaction converted
CO2 beyond chemical equilibrium. On the other hand, H2 conversion wassmaller than CO2 conversion probably because the formation of water isprobably the rate-determining step for the RWGS.2014 Annual Meeting of The Institute of Electrostatics Japan

Study on the Decomposition Performance of theFormaldehyde by Photocatalyst which Processed by theIndirect Dielectric Barrier Discharge○Tomonari TSURUMI, Masashi TOJO, Shota YAZAWA, Yusuke KUDO, Tetsuro

College of Industrial Technology, Nihon University

Abstract:
A photocatalyst works by only light. It is very clean and can be used
semipermanently. Therefore, a photocatalyst is environment-friendly. A
photocatalyst has a useful characteristic such as an oxidative decomposition
and a super-hydrophilicity. We have been studying about the removal
performance of the formaldehyde by photocatalyst substrate which processedby an electric discharge. In this study, indirect electric discharge was used forprocessing substrates. The evaluation method of substrate was formaldehyde
decomposition.

Yamagata University*，KASUGA DENKI. INC. **Abstract:
Although there are many sheet products stuck by glue or adhesivematerial, it is very difficult to stick and peel with keeping strong force by theseadhesive materials. In this study, we proposed an electrostatic sheet stapler thatcan stick and peel the sheet material by an electrostatic force. The sheet
material is charged by the positive and negative corona charging using two
needle and grid electrodes. It was found that the electrostatic sheet stapler cancontrol sticking and peeingl force by the corona charging and charge eliminationand that the sticking force is over than 50gf/cm2.
