本文旨在探讨水等离子体对有机化合物的分解机理。等离子炬可以产生100%的蒸汽直流放电，而无需商用蒸汽发生器。甲醇或乙醇作为水溶性有机化合物的模型物质与水混合作为等离子体支持气体。分解后的主要气体为H-2、CO和CO2。50%的碳在5mol %-乙醇分解过程中转化为固体碳，而5mol %-甲醇分解过程中形成的固体碳几乎可以忽略不计。乙醇分解生成的固碳量较大，说明甲醇与乙醇分解的机理不同。(C) 2009 Elsevier B.V.版权所有
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 CO2. The 50 wt.% of carbon was transformed into solid carbon in 5 mol%-ethanol decomposition, while the solid-carbon formation from 5 mol%-methanol was negligible. Larger amount of solid-carbon formation from ethanol decomposition indicates the different mechanism between methanol and ethanol decomposition. (C) 2009 Elsevier B.V. All rights reserved.
