Abstract
The purpose of this study is to investigate the application of DC water plasmas on liquid waste decomposition. Decomposition system of liquid waste by DC water plasma at atmospheric pressure has been developed. 1-Decanol emulsion used a model substance of water-insoluble organic compound was mixed with emulsifier (Tween 60) for plasma supporting gas. The decomposed gas was investigated with gas chromatography and mass spectroscopy. The main gases after the decomposition were H_2, CO, and CO_2. The mole fraction of H_2 in the decomposition gas was 68% in the decomposition gas. The water plasma system can be used for industrial application of liquid waste decomposition.
