Oxidation of hydrocarbons and oxygenates in supercritical water
The project, Supercritical Oxidation of Hazardous Chemical Wastes,'' is a Hazardous Waste Remedial Program Research and Development task being carried out by the Los Alamos National Laboratory. Its objective is to achieve an understanding of the technology for use in scaling up and applying oxidation in supercritical water as a viable process for treating a variety of Department of Energy Defense Programs waste streams. This report presents the results of a study of the chemical kinetics of the oxidation of one-carbon compounds in supercritical water. The experimental and modeling results obtained on these model compounds indicate that the mechanism of oxidation in supercritical water can be presented by free-radical reactions with appropriate modifications for high pressure and the high water concentration. If these conclusions hold true for higher-molecular-weight compounds, a large body of existing literature data on the kinetics of elementary reactions can be utilized to predict the oxidation kinetics and destruction and removal efficiencies of other compounds and their mixtures in pilot or commercial scale facilities. 8 figs., 16 refs., 4 tabs.
