Note:
This paper shows the main results of the preliminary experimental tests set up in the MOSCA (Metal Oxides for Sulphur Compounds Adsorption) bench scale plant in the Sotacarbo Laboratories. The sulphidation of commercially produced ZnO based sorbents has been investigated over a range of operating conditions relevant to the Sotacarbo pilot plant. A non-reducing bi-component mixture of H2S and N2 (with a H2S concentration of 1.5% in volume) has been selected in order to reproduce the typical H2S concentration in a coal syngas obtained through the gasification of Sulcis coal in an air-blown fixed-bed gasifier.
