Abstract

Abstract:

Based upon demonstrating the discharge mechanism and plasma characteristic of spark discharge, electrode configuration and plasma reactor of spark discharge were discussed especially. A novel kHz AC spark discharge reactor with rotating electrode, developed in our group, was applied in methane pyrolysis to produce acetylene and reforming of methane with CO₂ to produce syngas. Its discharge stability, reactant conversion, product concentration and energy efficiency are higher obviously than those of other discharge reactors.

Key words: Spark discharge, Atmospheric-pressure non-thermal plasma, Plasma ignition, Fuel reforming, Electrical discharge machining, Nano-material preparation
