Karlsruhe Nuclear Research Center, Institute of Hot Chemistry. Progress report on research and development work in 1993
Description
The R and D project under review focuses on the development of methods for annihilation (total oxidation) of resistant chemical pollutants with emphasis on the annihilation of halogenated organic compounds. The basic application of chemical reactions to supercritical media, and to supercritical water in particular, is investigated. The present research activities cover investigations into the thermal treatment of highly contaminated solids through oxidation in supercritical fluids, extraction methods for decontamination of solids by means of supercritical fluids, and electrooxidation of organic pollutants by means of redox mediators. Methodical studies are made of the physico-chemical properties of supercritical systems, of supercritical reaction kinetics, phase formation and phase fluctuation, and reactive mass transfer. Models are developed for the respective reactions, mechanisms of formation and transfer processes. (orig.)

Schwerpunkt des F+E-Programms ist die Entwicklung von Verfahren zur Vernichtung (Totaloxidation) resistenter chemischer Schadstoffe, besonders von halogenierten organischen Verbindungen. Vorzugsweise wird die Anwendung chemischer Reaktionen in ueberkritischen Medien, besonders ueberkritischem Wasser, als Verfahrensgrundlage untersucht. Im einzelnen werden derzeit bearbeitet: - Thermische Behandlung von hochkontaminierten Feststoffen durch Oxidation in ueberkritischen Fluids. - Extraktionsverfahren zur Dekontamination von Feststoffen mit ueberkritischen Fluids. - Elektrooxidation von organischen Schadstoffen mit Redox-Mediatoren. Methodisch werden dazu folgende Arbeiten durchgefuehrt: - Physikalisch-chemische Eigenschaften von ueberkritischen Systemen, - Reaktionskinetische Untersuchungen im ueberkritischen Zustand, -Phasenbildung und Phasenfluktuationen, - Reaktive Stoffuebergaenge, -Modellentwicklung fuer die oben erwaehnten Reaktionen, Bildungsmechanismen und Transfer-Vorgaenge.
