Abstract: The adsorbents were prepared for sewage sludge, waste oil sludge and metal oil sludge. On the materials obtained dynamic adsorption of H₂S was measured. The initial and exhausted adsorbents were characterised using sorption of nitrogen, thermal analysis, and XRF, XRD and surface pH measurements. The adsorbents have high capacity for H₂S (10% wt) The high volume of mesopores contributes significantly to reactive adsorption and provides space to store sulphur as the oxidation product. The highly dispersed mineral-like phase formed during pyrolysis provides basicity and catalytic centres for hydrogen sulphide dissociation and its oxidation to sulphur.
