Abstract
The present invention concerns a process for eliminating, reducing and/or suppressing halogenated compounds, in particular chlorinated compounds, contained in a gas or a liquid, in which the gas or liquid is brought into contact with a composition obtained by depositing at least one compound comprising at least one element selected from alkalis on an alumina, followed by calcining the alumina at a temperature of at least 600° C.When at least one compound comprising at least one element selected from alkaline-earths and rare earths is deposited on the alumina, the alumina calcining temperature is at least 500° C.
