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.

Pages : 29
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.

Supercritical Water Processing Technologies for Environment, Energy and Nanomaterial Applications
Author: Shuzhong Wang
Publisher: Springer Nature
ISBN: 9811393265
Category : Technology & Engineering
Languages : en
Pages : 352
Book Description
This book systematically presents the technical aspects of supercritical water oxidation and supercritical water gasification for energy and environmental applications, which include reactor design, construction materials, corrosion, salt precipitation, etc. The book provides a comprehensive introduction to the properties of supercritical water, and the industrial applications, reaction mechanisms and reaction kinetics of supercritical water oxidation (SCWO) and supercritical water gasification (SCWG). The reactions occurring in supercritical water are complex, and studying their reaction mechanisms is of great importance for the development of supercritical water processing technologies. Accordingly, the book explains the oxidative mechanisms and kinetics of organic matter in supercritical water in detail. However, the harsh reaction conditions in supercritical water can easily create severe reactor corrosion and salt deposition problems. Therefore, the book also comprehensively reports on the mechanism analysis, state of research, and development trends regarding these two problems. Lastly, the book summarizes the development of supercritical water processing technologies, including studies on SCWO and SCWG, as well as near-zero-emission systems of pollutants based on SCWO technology. In short, the book provides a wealth of valuable information for all readers who are interested in using SCWO for organic waste treatment, and in using SCWG for hydrogen production with wet biomass.
