Decomposition of benzene using non-thermal plasma reactor packed with ferroelectric pellet

The decomposition of benzene in air was carried out using a non-thermal discharge plasma reactor packed with ferroelectric materials. It was found that the ferroelectric materials having the diameter of 1-2 mm and a relative dielectric constant of epsilon(r) greater than or equal to 1100 exhibited the most effective energy efficiency for the decomposition of benzene. Benzene of low concentration, below 50 ppm, was completely decomposed to CO and CO2 without the formation of other hydrocarbons. The ratio of CO to CO2 produced from benzene was minimized under the atmosphere containing more than 5% of O-2.
