Ethylene decomposition with a wire-plate dielectric barrier discharge reactor: parameters and kinetic study

摘要: Ethylene is an undesirable compound for the storage of horticultural products. The traditional fresh-keeping method fruits and vegetables refrigeration. However, even in refrigeration environment, ethylene released by products themselves or other sources. residual can accelerate maturation corruption thus should better be wiped away. technique dielectric barrier discharge was applied to decompose ethylene. Under electric discharge, many energetic highly reactive species produced, which react with chemical compounds contact them. In this study, efficiency removal using reactor studied. rates were affected factors, such as gas gap, wire distance, flow rate, initial concentration humidity. kinetics To disintegrate ethylene, optimal gap 3 mm, distance 0.5 rate 3.5 L min−1 humidity 61 %. Two models selected decomposition, experimental results could fit model a maximum absolute error 4 With condition, totally removed. future, decomposition technology will promising keep fresh.
