A cyclic process of purification of gases containing at least two undesirable products by adsorption on a bed divided in at least two sections in which the regeneration is realized in a first stage by introducing on the adsorption bed countercurrently to the adsorption direction, after depressurizing, wherein the said gaseous mixture is obtained by combining with a given volume of reactivation gas a stream of gas coming out from between the two sections of the bed, a flow of said mixture equivalent to said volume of reactivation gas being passed through the first adsorption section. |
