Influence of C atom concentration for acetylene production in a CH4/N2 afterglow

Dilute Methane Treatment by Atmospheric Pressure Dielectric Barrier Discharge: Effects of Water Vapor

“…Toward this objective, the presented work specifically focuses on the influence of water vapor on methane oxidation by means of an atmospheric pressure dielectric barrier discharge (DBD). Previous studies on dilute methane treatment by non-thermal plasma at atmospheric pressure alone [13][14][15] and in combination with catalysts [16] have been done. The present work expands on these studies and will be discussed in light of them.…”

Decomposition of greenhouse gases by plasma

“…This characteristic made it suitable for chemical synthesis selection. Methane utilization using glow discharge (Diamy et al 2001;Legrand et al 1997Legrand et al , 1999, dielectric barrier discharge (Kado et al 2004;Zhang et al 2003;Hwang et al 2003, Kim et al 2003a2003b, Jeong et al 2001, Larkin et al 2001, corona (Legrand et al 1997, Liu et al 1997, spark (Legrand et al 1997), arc plasma-jet (Coltrin and Dandy 1993), radio frequency plasma (Savinov et al 2004) and thermal plasma (Fabry et al 2001, Kim 2004) have been investigated already. Other parameters of plasma methane reaction, such as plasma power generator (Yao et al 2001, Song et al 2004a, catalyst process-assisted (Kim et al 2004, water vapor injection (Hijikata et al 1999) were also investigated experimentally.…”

“…Higher HCs could be formed by coupling reactions of methyl radical (Indarto et al 2008) or carbon with radical species (Diamy et al 2001).…”

“…In some particular cases, the reaction between carbon and radical shows important role, especially in the case when the concentration of acetylene is the highest among other products (Diamy et al 2001). Legrand et al (1997Legrand et al ( , 1999 the investigation have investigated methane conversion using dielectric barrier discharge.…”

“…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.…”
