Investigation of Plasma Assisted Low-temperature Oxidation of DME

For a better understanding of the role of kinetic enhancement mechanism in the plasma assisted combustion (PAC), the well-defined experimental platform has been developed to elucidate the fundamental plasma-assisted kinetic enhancement mechanisms. With this apparatus, a nearly full view of speciation information including ions, excited species and radicals can be detected. A comprehensive study of plasma assisted low-temperature oxidation of dimethyl ether (DME) was conducted, which allowed for the identification of 10 ions and 13 neutral species. With the help of the detailed speciation information, we can make an effort to elucidate how the low-temperature reactivity of DME was enhanced by the plasma. Moreover, we can get more support in the work of kinetic model development of the plasma-assisted DME low-temperature oxidation. © 2020, Science Press. All right reserved.
