“…Gas phase reactions using dielectric barrier discharge (DBD) cold plasma are highly interesting as new reaction routes become feasible at mild conditions. The partial oxidation of methane in DBD cold plasma has been studied experimentally by many authors [ 1–35 ] and several reviews [ 36–39 ] provide an overview of the results. We refer here to uncatalyzed partial oxidation of methane (CH 4 ) with pure oxygen (O 2 ) in DBD cold plasma and only mention that also studies of that reaction in the presence of a catalyst and other reactants exist.…”

In the present work, the application of dielectric barrier discharge (DBD) cold plasma technology for the partial oxidation of methane was systematically studied. Conversion of the reactants and selectivities were measured using an elaborate product analysis from a recent work by Müller et al. varying the reactant ratio in the feed, the mole fraction of the inert carrier gas argon in the feed, and the specific energy input at operating conditions close to ambient. The results from 20 new experiments carried out in the present work complement 23 previous experiments and provide an unprecedented comprehensive quantitative data set. This extends the available knowledge of partial oxidation of methane in DBD cold plasma considerably and is useful for testing mechanistic models.

“…Plasma catalysis is attracting substantial interest in various environmental applications such as gas contaminant removal, gas conversion, and O 3 production [1][2][3][4][5][6][7][8][9][10][11]. Plasma catalysis is a combination of plasma and catalyst, with the advantages of catalyst selectivity and plasma high efficiency.…”

Different shapes of dielectric packing beads could affect streamer propagating direction, plasma streamer behavior, and streamer types, such as surface discharge, surface-to-surface discharge, and volume discharge. In this paper, a 2D particle-in-cell/Monte Carlo collision model is used to investigate the effect of the bead shapes on streamer characteristics in packed-bed dielectric barrier discharges. We calculate the electron density, ion density, excitation rate, ionization rate and the electric field with different bead shapes in two cases of seed electron configurations. The results demonstrate that both the configurations of seed electrons and the shape of beads could influence plasma properties. In the case of seed electrons located directly above the beads, the streamer cannot be generated with square beads, while weak surface ionization waves (SIWs) are developed with circle and triangle beads, when the distance between the seed electrons and the upper plate is as close as 0.02 mm. Whereas, the distance between the seed electrons and the upper plate is 0.06 mm, the streamers can be generated with all three bead shapes, but SIWs are still weak. This is because different shapes of beads induce different electric field and surface charging along the dielectric bead surfaces, determining the generation of SIWs. In the case of seed electrons placed between two beads, streamers can propagate in all three bead shape configurations, and the SIWs are enhanced.

“…[1] Low-temperature plasma can generate different kinds of active particles by changing the chemical bond structure of stable gas molecules (such as CO 2 gas) through high-voltage electric field techniques. [6] It has been extensively investigated as an alternative sterilization method. [7] Research on inner tube plasma generation methods has been carried out in two directions: low-pressure discharge plasmas and atmospheric pressure discharge plasmas.…”

Plasma bacteria decontamination devices for the inner surface of medical tubes have to consider more practical application problems, such as the processing compatibility for medical tubes of variable scales, a reasonable and effective design model for plasma electrode parameters, and so on. This paper proposes a novel multisegment‐casing ring‐ring jet (MSC‐RRJ) without embedding the electrode into the target tube, obtaining the variable tube length processing capability. And through establishing an effective design model based on electric field distribution properties, ensuring the electric field strength margin in each segment of MSC‐RRJ to achieve the processing capability of variable tube diameters. A prototype device is developed based on the proposed MSC‐RRJ electrode and design method being verified by killing Staphylococcus aureus and Escherichia coli.
