| 摘要 |
The invention concerns a method for eliminating, reducing, and/or suppressing halogenated compounds, and more particularly chlorinated compounds, contained in a gas or liquid, which consists in contacting the gas or liquid with a composition obtained by depositing on an alumina at least a compound comprising at least one element selected among alkalis, and subsequent to the deposit, in calcining the alumina at a temperature not less than 600 DEG C. When at least one compound comprising at least one element selected among the alkaline earths or rare earths, is deposited on the alumina, the temperature at which the alumina is calcined is at least 500 DEG C.
