Catalyst-free single-step plasma reforming of CH4 and CO2 to higher value oxygenates under ambient conditions
TL;DR: In this paper , the authors report a promising plasma process for the catalyst-free single-step conversion of CH4 and CO2 into higher value oxygenates (i.e., methanol, acetic acid, ethanol, and acetone) at ambient pressure and room temperature using a water-cooled dielectric barrier discharge (DBD) reactor.
Journal ArticleDOI
Plasma‐Assisted Reforming of Methane
TL;DR: In this paper , a review of plasma-assisted reforming of methane (PARM) is presented from the perspective of reactor development, thermal and nonthermal PARM routes, and catalysis.
Journal ArticleDOI
Hydrogen Production by Microwave Discharge in Liquid: Study on the Characteristics Effect of Suspended Electrode
TL;DR: In this paper , a three-electrode reactor was designed and a suspended electrode was added to further improve the hydrogen production efficiency of microwave liquid-phase discharge, and the formation of bubbles during the discharge and the change characteristics of plasma morphology were studied after adding the suspended electrode.
Journal ArticleDOI
Deep learning-assisted pulsed discharge plasma catalysis modeling
TL;DR: In this paper , a multi-layer feed-forward deep neural network was introduced into the plasma/plasma catalysis kinetics modeling, which enables the initial input parameters for kinetics simulation, such as reduced electric field (E/N), to be extracted from specific experimental data after the neural network has been well-trained.
Journal ArticleDOI
Parametric investigations on plasma‐activated conversion of CH 4 –CH 3 OH to C2–C4 alcohols by nanosecond pulsed discharge
TL;DR: In this article , an innovative synthesis of higher alcohols from CH4-CH3OH was driven by a highly flexible nanosecond pulsed plasma, and the products distribution was strongly correlated with the electric field variation and reactants composition, and a maximum conversion of CH4 (35.9%) and CH3OH (77.4%) were obtained at the CH4/Ar ratio of 1:2.

Cross Sections for Electron Collisions with Methane
Mi-Young Song,Jung-Sik Yoon,Hyuck Cho,Yukikazu Itikawa,Grzegorz P. Karwasz,Viatcheslav Kokoouline,Yoshiharu Nakamura,Jonathan Tennyson +7 more
TL;DR: In this article, cross section data are compiled from the literature for electron collisions with methane (CH4) molecules and cross sections are collected and reviewed for total scattering, elastic scattering, momentum transfer, excitations of rotational and vibrational states, dissociation, ionization, and dissociative attachment.

Journal ArticleDOI
Study of the dry methane reforming process using a rotating gliding arc reactor
TL;DR: In this paper, the influence of the operational conditions (applied voltage and CH4/CO2 ratio) on the basic spectroscopic parameters (electron excitation temperature, electron density and rotational temperature) of a rotating gliding arc discharge, co-driven by a magnetic field and tangential flow was investigated.
