摘要:

针对恶臭气体污染问题,以甲硫醚(DMS)为对象,研究介质阻挡放电等离子体协同V2O5 WO3/TiO2催化剂对恶臭气体降解的影响规律.考察不同参数(能量密度、气体流量、体积分数)对甲硫醚降解效果的影响及副产物生成规律.结果表明,V2O5 WO3/TiO2催化剂对甲硫醚的降解有明显的促进作用.随着V2O5质量分数的增加,催化剂比表面积减小,氧化还原性提升.甲硫醚降解效率和能量效率随V2O5质量分数的增加而增加.当V2O5质量分数为0.6%,能量密度为788.4 J/L时,甲硫醚降解效率为91.6%,甲硫醚降解的能量效率为6.54 g/(kW·h).甲硫醚初始体积分数越高,气体体积流量越大,降解效率越低.

Abstract:

Plasma catalytic removal of dimethyl sulfide (DMS) over V2O5 WO3/TiO2 catalyst was investigated in a dielectric barrier discharge (DBD) reactor in order to solve the problem of odor gas pollution. The influence of different experimental parameters (energy density, gas flow, volume fraction, etc.) on the plasma catalytic process was examined in terms of DMS removal efficiency, energy yield and the formation of by products. Results show that the combination of plasma with the V2OWO3/TiO2 catalyst significantly enhanced the removal efficiency of DMS. When the mass fraction of V2O5 increased, the surface area of catalyst decreased while reducibility increased. Then DMS removal efficiency and energy yield increased. When V2O5 loading mass fraction is 0.6%, the DMS removal efficiency achieved 91.6% and energy yield was 6.54 g/(kW·h) at the energy density of 788.4 J/L. DMS removal efficiency decreased with increasing flow rate and DMS initial volume fraction.
