Porous, preferably dimensionally stable material for the removal of gaseous impurities from a gas mixture, such as H2S, COS, CS2, and SO2, into the pores of which there is incorporated a secondary amine which chemically bonds with the constituents to be removed, with the material comprising a hydrophobic polymer with pores having an average diameter in the range of 0,1 to 50 mu m and a secondary amine having hydrophobic properties which optionally is incorporated into a hydrophobic liquid. Favourable results have been attained using polypropylene as the hydrophobic polymer and ditridecyl amine as the secondary amine, with a tertiary amine, such as C12/C14-alkyl diethanol amine, being part of the hydrophobic liquid. |
