The purpose of this paper is to investigate the decomposition mechanism of organic compounds by water plasmas. The plasma torch can generate 100%-steam by DC discharge without a commercially available steam generator. Methanol or ethanol used as a model substance of water-soluble organic compounds was mixed with water for plasma supporting gas. The main gases after the decomposition were H_2, CO. and CO_2. The 50wt% of carbon was transformed into solid carbon in 5mol%-ethanol decomposition, while the solid-carbon formation from 5mol%-methanol was negligible. Larger amount of solid-carbon formation from ethanol decomposition indicates the different mechanism between methanol and ethanol decomposition.
