“…In this work, the two graphite electrodes were substituted with two tungsten electrodes, and the origin of the carbon precursor was the carbon black which comes from the decomposition of the benzene in the reactor. Benzene was used as the origin of the carbon precursor because the hydrocarbon (benzene, methane, acetylene, ethylene) has no influence on the products' properties [9] and the experimental device can be simplified.…”

Carbon nanostructures have received much attention for a wide range of applications. In this paper, we produced carbon nanostructures by decomposition of benzene using AC arc discharge plasma process at atmospheric pressure. Discharge was carried out at a voltage of 380 V, with a current of 6 A-20 A. The products were characterized by scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HRTEM), powder X-ray diffraction (XRD), and Raman spectra. The results show that the products on the inner wall of the reactor and the sand core are nanoparticles with 20-60 nm diameter, and the products on the electrode ends are nanoparticles, agglomerate carbon particles, and multiwalled carbon nanotubes (MWCNTs). The maximum yield content of carbon nanotubes occurs when the arc discharge current is 8 A. Finally, the reaction mechanism was discussed.

The conversion of trichloromethane in mixtures with air was investigated under normal pressure in a gliding discharge (GD) reactor operated in both a homogeneous gas system and with a solid catalyst. The Pt catalyst supported by a honey-comb cordierite structure was placed in the reactor below the ends of the electrodes. Cl 2 and HCl were the main products of the CHCl 3 conversion. The presence of CCl 4 was also noted. The influence of the electrode length and the distance between the electrodes in the narrowest section on CHCl 3 conversion was examined. The Pt catalyst revealed some activity in the trichloromethane processing. This resulted in an increased overall CHCl 3 conversion with the portion of CHCl 3 converted to CCl 4 smaller than that in the homogeneous system. The effect of temperature on CHCl 3 conversion was found to be significant.

“…The advantage of nonequilibrium plasma lies in its nonequilibrium property: it has a high electron temperature (10 4 -10 5 K), whereas the gas temperature remains low (as low as room temperature), which leads to some unusual chemical performance. Direct methane conversion using discharge plasmas to syngas, 21 acetylene or other C 2 hydrocarbon, 12,[14][15][16]19,20 liquid fuels (methanol or higher hydrocarbons), 8,23 and oxygenates (such as acids and alcohols) [8][9][10][11] have been extensively investigated. Especially, direct synthesis of oxygenates and liquid fuels from methane using nonequilibrium plasmas has recently attracted much attention.…”

Plasma Methane Conversion in the Presence of Dimethyl Ether Using Dielectric-Barrier Discharge

2005

An experimental investigation was conducted to convert methane in the presence of dimethyl ether (DME), using dielectric barrier discharge (DBD) at atmospheric pressure and 100 °C. The co-feed of DME induces an increase in methane conversion, from 18.22% to 38.46%. The major products include C 2 and C 3 hydrocarbons, methoxy-containing oxygenates (methyl ethyl ether (MEE), dimethoxymethane (DMM), and dimethoxyethane (DMET)) and syngas (CO and H 2 ). The selectivity of products changes with the CH 4 /DME feed ratio. The larger the CH 4 /DME feed ratio, the higher the selectivity of light hydrocarbons. The highest selectivity of all the oxygenates is observed for a CH 4 /DME feed ratio of 1:1.
