The kinetics of products formation during adsorption at low temperature of gaseous H2S onto zinc and/or copper oxides supported on activated carbon is dealt in this work. Sorbents with a fixed total metal content and variable Zn:Cu ratios were prepared by impregnation of a commercial activated carbon. H2S (100 and 3000 ppmv in N2) removal tests were run under dynamic conditions at 30 °C. Raw and spent sorbents were characterized via N2 porosimetry at –196 °C to determine BET surface area and pore size distribution. XPS and TPD tests performed on partially converted and spent sorbents allowed the speciation of adsorbed sulphur species.

Abstract
The kinetics of products formation during adsorption at low temperature of gaseous H2S onto zinc and/or copper oxides supported on activated carbon is dealt in this work. Sorbents with a fixed total metal content and variable Zn:Cu ratios were prepared by impregnation of a commercial activated carbon. H2S (100 and 3000 ppmv in N2) removal tests were run under dynamic conditions at 30 °C. Raw and spent sorbents were characterized via N2 porosimetry at –196 °C to determine BET surface area and pore size distribution. XPS and TPD tests performed on partially converted and spent sorbents allowed the speciation of adsorbed sulphur species.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
