  Title Methane coupling in nanosecond pulsed plasmas: Correlation between temperature and pressure and effects on product selectivity Type A1 Journal Article
  Year (down) 2023 Publication Chemical engineering journal Abbreviated Journal  
  Volume 462 Issue Pages 142227  
  Keywords A1 Journal article; Plasma Lab for Applications in Sustainability and Medicine – Antwerp (PLASMANT)  
  Abstract We present a zero-dimensional kinetic model to characterise specifically the gas-phase dynamics of methane

conversion in a nanosecond pulsed discharge (NPD) plasma reactor. The model includes a systematic approach to

capture the nanoscale power discharges and the rapid ensuing changes in electric field, gas and electron temperature,

as well as species densities. The effects of gas temperature and reactor pressure on gas conversion and

product selectivity are extensively investigated and validated against experimental work. We discuss the

important reaction pathways and provide an analysis of the dynamics of the heating and cooling mechanisms. H

radicals are found to be the most populous plasma species and they participate in hydrogenation and dehydrogenation

reactions, which are the dominant recombination reactions leading to C2H4 and C2H2 as main

products (depending on the pressure).
