Tunable hybrid plasma decomposition of dilute concentrations of CCl4 in air

摘要

At the Department of Energy Hanford site, a large quantity of the industrial solvent carbon tetrachloride (CCl4) was used and subsequently disposed of in leaching fields. Efforts under the Volatile Organic Compound - Arid Integrated Demonstration Program (VOC-Arid ID) are directed at vapor extraction of carbon tetrachloride from the ground and its subsequent decomposition in the contaminated humid air stream. We are developing a mobile electron-beam driven plasma reactor for versatile efficient on-site decomposition of CCl4 and other VOCs in carrier gases at atmospheric pressure. The decomposition of the VOCs could result in the generation of CO(sub 2), light hydrocarbons, and reactive chlorine compounds. The latter dissolve and/or dissociate in aqueous solutions.
