Treatment of MSW fly ashes in plasma reactor: monitoring of chlorinated compounds desorption by mass spectrometry

摘要

In the present work, an RF low-pressure plasma reactor has been developed in order to study the desorption of chlorinated compounds from MSW fly ashes. Due to chemical complexity of a real MSW fly ashes, we have developed a model of fly ashes using a martrix of alumina, calcium oxide, silica and zeolites spiked with halogens and metals. Plasma/simulated fly ash interaction has been studied by on-line mass spectrometry.
