The dependence of nonthermal plasma behavior of VOCs on their chemical structures

The dependence of nonthermal plasma behavior of volatile organic compounds (VOCs) on their chemical structures was investigated, using methane, ethane, ethylene, butane, 1,1,2-trichloroethane, trichloroethylene, and tetrachloroethylene as target VOCs. It has been shown that the above VOCs decompose...

Description
Summary:The dependence of nonthermal plasma behavior of volatile organic compounds (VOCs) on their chemical structures was investigated, using methane, ethane, ethylene, butane, 1,1,2-trichloroethane, trichloroethylene, and tetrachloroethylene as target VOCs. It has been shown that the above VOCs decompose homolytically via their excited states, irrespective of their electron affinities. Efficiencies of energy transfer from hot electrons to the VOCs could be important in the initial steps of their decomposition. Active oxygen species can be involved in the decomposition of nonchlorinated hydrocarbons under humid conditions. Byproduct distributions have been affected by residence time, carrier gas, and humidification, depending on VOC structures.
