Abstrakt: Honeycomb catalysts are used in cars for the exhaust gas removal. Their performance depends on gas composition and temperature and can be improved by a combination with plasma. Generation of homogenous and stable plasma inside thin channels of honeycomb catalysts is, however, rather difficult. The paper presents a novel method of setting up stable discharge plasma inside thin channels utilizing a sliding discharge. The sliding discharge is a discharge generated on dielectrics by combination of AC and DC powers in three-electrode geometry. The discharge
can be generated either on flat dielectric surfaces, or along the inner surface of the glass capillaries. The basic characteristics of the sliding discharge inside the capillary channels, addressing the effects of the length of the capillaries and the applied voltage, are presented.
