介质阻挡放电协同催化萘降解
Naphthalene Degradation by Dielectric Barrier Discharge Coupling Catalyst
摘要
Abstract
To improve the naphthalene degradation,we put forward a method of dielectric barrier discharge (DBD) coupling catalyst.Moreover,we studied the effect of packed media on discharge characteristics and naphthalene degradation,and deeply analyzed the influence mechanisms of naphthalene degradation under different TiO2 loads and gas temperatures.The results show that the packed TiO2/diatomite has a negative function on DBD discharge,and it can lead to the decrease of peak current.Compared with that of no packed TiO2/diatomite,the degradation rate of naphthalene and COx selectivity of packed TiO2/diatomite improves obviously,especially the COx selectivity increases nearly by 30％.With the increase of loaded amount of TiO2 on the diatomite,COx selectivity increases from 47.5％ to 76.5％.The CO2 selectivity increases by 24.2％,while the CO selectivity is only 4.8％.As the temperature of simulated gas rises from 25 ℃ to 100 ℃,the degradation rate of naphthalene increases only from 83.8％ to 91.8％.However,the COx selectivity enhances from 45.3％ to 87.5％,nearly double.YiO2 has played an important role in the process of naphthalene degradation,which provides a new evidence for the harmless treatment of non-degradable organic gas.关键词
