| abstract |
The invention relates to an adsorbent comprising an alumina support and at least one alkaline element, said adsorbent being obtained by introducing at least one alkaline element, identical to or different from sodium, onto an alumina support having a sodium concentration, expressed as Na 2 O equivalent and prior to the introduction of the alkaline element(s), of between 1000 and 5000 ppm by weight in relation to the total weight of the support. The invention also relates to methods for the production of the adsorbent and to the use thereof in a method for the elimination of acid molecules, such as COS and/or CO 2 . |
