摘　　要：采用滑动弧放电低温等离子体催化协同技术研究了催化剂床填充材料、初始浓度、流量等对正己烷降解的影响。研究表明,滑动弧放电催化协同技术可以实现正己烷的有效裂解。对于反应器中不同的填充材料,蜂窝状催化剂优于颗粒状;降解率以蜂窝状Al2O3填充时最高;单位功耗以填充蜂窝状Al2O3最小。无论是以Al2O3填充还是以Pt/Pb催化剂填充,正己烷的降解率均随初始浓度、流量的增加而呈现降低的趋势,但绝对处理量增大。The gliding arc discharge combined with a catalytic bed was applied for destroying gas phase hexane decomposition. The effects of initial hexane concentration, element of catalyst and the flow flux were studied. It was found the effect of alveolate catalyst was better than that of the pellet catalyst in the whole decomposition system. The removal efficiency of hexane can get the highest level whereas the consumption of energy was the minimum when alveolate Al2O3 was filled in the catalytic bed. The decomposition rate reduced with the initial hexane concentration and its flux, no matter which was filled in the catalytic bed.
