“…Even though the measurements presented above show much energy going toward creation of excited molecular N 2 *, there is plenty of literature that proves beyond doubt that AP DBD N 2 discharges can result in efficient dissociation, which requires 9.79 eV for N 2 bond‐breakage. Work recently published by Peeters et al using a pure nitrogen AP plasma jet, constitutes a good example. Having stated this, we are regrettably still no closer to explaining the very low value, ( E m ) max = 1.9 eV, observed in Figure .…”

A large research reactor for performingdielectric barrier discharge (DBD) experiments at atmospheric pressure (AP) has been used with argon (Ar) carrier gas under constant plasma conditions (f ¼ 20 kHz, V a (f) ¼ 8 kV p-p ¼ 2.8 kV rms ). Various permanent gases (H 2 , O 2 , N 2 , light hydrocarbons) and some heavier organic molecules were introduced as reactive ''dopant'' flows, F d , at ‰ concentrations in the F ¼ 10 standard liters per minute (slm) flow of argon. We have earlier perfected and reported a method for measuring E g , the energy dissipated per cycle of the applied a.c. voltage, and DE g , the energy difference with and without reactive dopant in the Ar flow. The latter and F d permit calculation of E m , the energy absorbed from the plasma by each dopant molecule. Plots of E m versus F d and 1/F d yield much valuable information about excitation, fragmentation, and polymerization in the DBD plasma environment. Optical emission (OES) and Fourier-transform infrared (FTIR) spectroscopies help to further enhance and complement interpretation of measured data.

“…By substituting Eqs. (12) and (13) in (11) and solving for n e,res we find the minimum gas-phase electron density required to have a noticeable plasma current throughout a full period of the applied voltage: n e, res ≫ ε 0 2πf eμ e ≈ f Á 10 10 m À3 :…”

“…Though spatially uniform discharging in DBDs can be achieved under certain conditions [1][2][3][4][5][6][7], under most circumstances a filamentary discharge will develop [8]. Since filaments are characterised by high local electron densities of up to 10 15 cm À3 and strong electric fields of up to 10 5 V/cm, it is these filaments that determine the plasma chemistry [9][10][11]. The filaments are self-limiting, because they charge the dielectric surface and locally negate the gap voltage until extinction occurs within 10 À7 s. Not only are the filaments spread out over the surface, they also occur over a wide timeframe.…”

“…This ignition voltage tends to be constant and is here referred to as the 'burning voltage' U b , as depicted in Figure 1. The burning voltage U b provides a measure for the (reduced) electric field within the DBD plasma and is highly relevant for assessing the plasma chemistry occurring within the reactor [11,13]. Along with large scale discharges, individual filaments have also been a subject of study, both experimentally [10,[14][15][16] and in modelling [9,10,17,18].…”

Atmospheric Pressure Plasma - From Diagnostics to Applications

View full text Add to dashboard Cite

Atmospheric pressure dielectric barrier discharges (DBD) has many industrial applications and remains a focus of academic research. This chapter provides a thorough overview of electrical diagnostics for DBD, with a specific focus on charge-voltage measurement techniques. These methods are often underutilised in the existing scientific literature, despite the fact that they can provide useful insights into plasma behaviour. Both optimization of the electrical measurement setup and the interpretation of results are treated in-depth. The diagnostic techniques are discussed for a range of applications, from classic planar DBDs, to catalyst packed beds, plasma actuators, as well as techniques for measuring single microdischarges.

“…is typically filamentary. Hence, a lower power may also manifest itself in less filaments instead of a lower electric field in these filaments (Peeters et al, 2015;Ozkan et al, 2016). Thus, it would not be straightforward to control the electric field values in a DBD plasma.…”

Plasma Technology for CO2 Conversion: A Personal Perspective on Prospects and Gaps

2020

View full text Add to dashboard Cite

There is increasing interest in plasma technology for CO 2 conversion because it can operate at mild conditions and it can store fluctuating renewable electricity into value-added compounds and renewable fuels. This perspective paper aims to provide a view on the future for non-specialists who want to understand the role of plasma technology in the new scenario for sustainable and low-carbon energy and chemistry. Thus, it is prepared to give a personal view on future opportunities and challenges. First, we introduce the current state-of-the-art and the potential of plasma-based CO 2 conversion. Subsequently, we discuss the challenges to overcome the current limitations and to apply plasma technology on a large scale. The final section discusses the general context and the potential benefits of plasma-based CO 2 conversion for our life and the impact on climate change. It also includes a brief analysis on the future scenario for energy and chemical production, and how plasma technology may realize new paths for CO 2 utilization.
