Abstract
Atmospheric pressure plasma conversion of methane is usually addressed in gas-only systems, such as dry reforming of methane. Introducing a liquid in such a system enables direct utilization of plasma-produced radicals, such as methyl (CH3), as a reactant in the liquid. Methylation of organic liquids by this technique can lead to the sustainable production of high-value products. A dielectric-barrier-discharge (DBD) microfluidic reactor having a 500 μm × 500 μm cross-section was developed to investigate the characteristics of methane-containing atmospheric pressure plasmas in contact with organic solvents. The sensors included optical emission spectroscopy and chip surface temperature measurement to estimate and predict plasma initiation in these methane-containing systems and provide insights into the plasma-liquid interfacial behavior. Fluids having high liquid hold-up, low boiling point, and low dielectric constant have been found to have adverse effects on non-equilibrium DBD methane plasma ignition.
期刊介绍：
Lab on a Chip is the premiere journal that publishes cutting-edge research in the field of miniaturization. By their very nature, microfluidic/nanofluidic/miniaturized systems are at the intersection of disciplines, spanning fundamental research to high-end application, which is reflected by the broad readership of the journal. Lab on a Chip publishes two types of papers on original research: full-length research papers and communications. Papers should demonstrate innovations, which can come from technical advancements or applications addressing pressing needs in globally important areas. The journal also publishes Comments, Reviews, and Perspectives.
