Hydrogen production via plasma methane pyrolysis is investigated using a microwave plasma torch (MPT) and a gliding arc plasmatron (GAP). The performance of the two plasma sources in terms of methane conversion, product spectrum, and energy...
NO synthesis using plasma catalysis is analyzed in a parallel-plate atmospheric pressure RF plasma from N$_2$/O$_2$ admixed to helium exposed to Fe and Pt catalysts on a SiO$_2$ support. The NO$_x$ species are measured by Fourier-transform...
Dielectric barrier discharges (DBD) are often used for gas conversion, such as carbon dioxide splitting, volatile organic compound removal or ozone generation. Due to the tiny plasma filaments in DBD discharges, efficient mixing of the gas flow...
The plasma catalytic oxidation of n-butane diluted in a helium-oxygen RF plasma jet is used to study volatile organic compound (VOC) removal to unravel plasma catalytic synergisms. The plasma conversion is tested for a stoichiometric n-butane...
The in-plasma-catalytic synthesis of ammonia from nitrogen and hydrogen admixed to a helium RF plasma is studied with infrared absorption spectroscopy, optical emission spectroscopy, and through chemical kinetics modeling. Sandblasted glass is...
Atmospheric pressure plasmas are widely used for nitrogen fixation processes to produce ammonia NH3 or nitrogen oxides NOx , including for example nitrite NO2– or nitrate NO3–. Small scale atmospheric pressure plasma jets (APPJs) can provide the...
In this work, the transport of hydroxyl radicals and hydrogen peroxide from a humid atmospheric pressure plasma jet into plasma-treated liquids is analysed. The concentration of H2O2 was measured by a spectrophotometric approach using the reagent...
This study investigates the flow field induced by a surface dielectric barrier discharge (SDBD) system, known for its efficient pollution remediation of volatile organic compounds (VOCs). We aim to understand the flow dynamics that contribute to...
Magnitude of the electric field of the microwave plasma torch simulated with ansys HFSS
Numerous studies have shown that dielectric barrier discharge (DBD) and DBD-like plasma jets interact with a treated surface in a complex manner. Eroded traces after treatment cannot be explained by conventional plasma-surface interaction theory....
