The invention relates to a porous adsorbent comprising pores having a pore diameter (Dm) of between 1 nm and 14 nm and furthermore having an oxygen adsorptivity, measured at +20°C and 1 bar, of at most 10 Scc/g, as well as to the use of this adsorbent for adsorbing at least one gaseous compound contained in a gas mixture containing several gaseous compounds of different polarity. Preferably, the gas mixture to be separated or to be purified is chosen from mixtures containing oxygen and nitrogen, particularly air, mixtures containing carbon monoxide and hydrogen, and hydrocarbons, especially olefins. Advantageously, the process is of the PSA or VSA type.
