Book Description
This project consists of experiments and theoretical modeling designed to improve our understanding of the detailed chemical kinetics of supercritical water oxidation (SCWO) processes. The objective of the three year project is to develop working models that accurately predict the oxidation rates and mechanisms for a variety of key organic species over the range of temperatures and pressures important for industrial applications. Our examination of reaction kinetics in supercritical water undertakes in situ measurements of reactants, intermediates, and products using optical spectroscopic techniques, primarily Raman spectroscopy. Our focus is to measure the primary oxidation steps that occur in the oxidation of methanol, higher alcohols, methylene chloride, and some simple organic compounds containing nitro groups. We are placing special emphasis on identifying reaction steps that involve hydroxyl radical, hydroperoxyl radical, and hydrogen peroxide. The measurements are conducted in two optically accessible reactors, the supercritical flow reactor (SFR) and the supercritical cell reactor (SCR), designed to operate at temperatures and pressures up to 600 deg C and 500 MPa. The combination of these two reactors permit reaction rate measurements raging from 0.1 s to many hours.

Book Description
This final report has two purposes. The first is to provide a single document that contains a description of this project's goals, activities, and accomplishments over the 8 year period of performance from January, 1993 to August, 2000. The second purpose is to provide an overview of the technical results that have been obtained and to submit a roadmap that identifies the publications and reports where the details of these technical results can be found. This report is not intended to republish the complete contents of the quarterly progress reports of the several dozen reviewed publications and Sandia reports that have resulted from this project. However, sufficient detail of the experimental and modeling results is included to illustrate the most important technical conclusions. Specifically, detailed results are presented here that answer the two fundamental questions that have motivated this work. They are: (1) what are the rate-controlling processes in the oxidation of a variety of organic compounds in supercritical water; and (2) how does this oxidation chemistry compare to combustion chemistry and, if so, can the same elementary reaction modeling approaches that have met with success.

Book Description
(Cont.) at well-defined operating conditions and to develop. both microscopic and macroscopic models, ranging from regressed global models to an elementary reaction mechanism, to quantify MPA oxidation kinetics in supercritical water. MPA hydrolysis and oxidation rates were experimentally measured in a laboratory-scale plug flow reactor. The effects of MPA concentration (0.5 to 1.0 mM), oxygen concentration (1.0 to 3.8 mM), temperature (478 to 572°C) and pressure (138 to 277 bar) on oxidation rates were determined for residence times ranging from 3.0 to 9.5 s. Conversion due to hydrolysis was less than 6% after [tau]=7 s at all temperatures studied. For [tau]=7 s at stoichiometric conditions and P=246 bar, low conversion (X
