1. A method of removing hydrogen sulphide from hydrocarboncontaining gas mixtures by means of activated carbon at high temperatures, characterised in that the gas is freed of the gas components preventing the catalytic H2 S-oxidation in a first stage (preliminary filter) at temperatures between 100 and 250 degrees C in a reactor filled with an activated carbon having a pore volume of 0.3-0.8 cm**3 /g (adsorption pore volume) measured by benzene adsorption and a pore volume of 0.3-0.9 cm**3 /g (supply pore volume) determined by mercury porosimetry and a BET surface of 700-1,500 m**2 /g, after which the hydrogen sulphide is oxidized and removed from the gas in an adsorptive manner in a reactor filled with an activated carbon catalyst in a second stage (desulphurizing reactor) following the addition of the quantity of oxygen required for the catalytic H2 S-oxidation. |
