摘要

研究了以超临界水氧化法（ＳＣＷＯ）处理乙醇废水的过程。实验表明，一氧化碳和二氧化碳分别是反应中间产物和最终产物。５５０℃、２５ＭＰａ、停留时间大于１０ｓ时，ＳＣＷＯ能将乙醇完全氧化为二氧化碳，达到彻底处理的目的。随停留时间增大、温度升高，乙醇的去除率增大，而压力和氧气浓度的变化对过程没有显著影响。

Abstract

There is growing interest in applying supercritical water oxidation (SCWO) to the treatment of wastewaters arid sludgest As the typical representation of alcohols wastewater ethanol was selected and its oxidation in supercritical water was investigated. The experiments were performed in an isothermal

plug-flow reactor at temperatures from 748.2 to 823.2K

pressures from 22 to 30 MPa

reactor residence times from 0.6 to 63.7s

and oxygen/ethanol molar feed ratios from 4.56 to 9.09. The oxidation of ethanol was fast in supercritical water At temperature of 823.2K

pressure of 25MPa and residence time of more than 10s

the reaction conversion of ethanol to carbon dioxide was near 100 percent. Monoxide was the major intermediate of the process. The ethanol conversion increased with increasing residence time and temperature and did not obviously change with varying pressure or oxygen concentration.
