“…In our previous report [16], the methane conversion is limited to 9.5%, but the main product is ethane (nearly 60%) followed by propane (around 20%). The distributions of these main products by DBD are also similar values to the other reports [9][10][11][12][13][14][15], improving the methane conversion by use of catalysts, although the increase of C 2 selectivities has been limited by ca. 20%.…”

“…Subsequently, intensive investigations on dehydrogenative (nonoxidative) coupling of methane have been conducted in atmospheric nonthermal plasmas generated by spark discharge or dieletric-barrier discharge (DBD) without catalysts [9][10][11] and by DBD with special catalysts [12][13][14][15]. Ethane is the main product of these methane activation techniques, and the selectivity was as much as 60%, accompanying unsaturated and C3+ hydrocarbons.…”

The effect of coexistence of hydrogen on the product selectivity to ethane from methane by dielectric-barrier discharge (DBD) reactor was examined experimentally under ordinary pressure without use of catalyst and external heating. By the dilution of methane with hydrogen, both the increase of methane conversion and the decrease of alkene production were observed, improving the selectivities to ethane by ca. 70%.

The carbon dioxide reforming of methane to synthesis gas under DC-pulsed plasma was investigated. The effects of specific input energy and feed ratio on the product distribution and also feed conversion was studied. At the input energy of about 11 eV/ molecule per methane and/or carbon dioxide the feed conversion of 38% for CH 4 and 28% for CO 2 and product selectivity of 74% has been attained for H 2 and CO at feed flow rate of 90 ml/min. The energy consumption in this work displays potential to further study and optimization of the process. The importance of the electron impact reactions in the process was discussed. The results show that by prudent tuning of system variables, the process be able to run in the way of synthesis gas, instead of hydrocarbon production.

“…Diamy et al (2001;Legrand et al 1997Legrand et al , 1999 found that the acetylene formed the majority of the products when corona-like discharge was used. Other groups (Kim et al 2003a(Kim et al , 2003bJeong et al 2001;Indarto et al 2008) found ethane (C 2 H 6 ) as the major products although the distribution could be different with some process manipulations or optimization. By kinetic calculation, Indarto et al (2005b) showed that the concentration of ÁCH 3 radical (ÁCH 3 ) and hydrogen atom (H) was increased sharply just after the initiation of plasma reaction, then ÁCH 3 was consumed and reacted to form higher mass molecules.…”

The topic of decomposition and reduction of greenhouse gases is becoming an important issue in tackling the global warming effect since several years ago. Several technologies, including plasma-utilized process, were proposed to improve the treatment ability for the destruction of green house gases usually emitted by industrial activities. In this review paper, the application of plasma to reduce the emission of greenhouse gases was briefly summarized.
