Trace Methane Destruction within the Effluent of Microwave Plasma.

ABSTRACT: Atmospheric methane concentrations have more than doubled since preindustrial times, intensifying the global climate crisis. We experimentally examined the performance of microwave plasma for the destruction of trace methane (<1 mol %), emulating a cow barn. We evaluated a range of gases in the plasma and injected methane-containing air downstream, aiming to use excited species formed in the plasma to convert methane into valuable products, as well as species with a lower global warming potential, such as CO₂. Fourier transform infrared spectroscopy (FTIR) was used to measure the concentration of methane and other IR-active products within the reactor effluent. Our analysis indicates that none of the tested experiments demonstrate lower energy costs than the already existing met
