International audience; This paper focuses on the valorization of calcium carbonate-based solid wastes for theremoval of hydrogen sulfide from gas phase. Two solid wastes taken from industrial sites for theproduction of sodium carbonate and sodium bicarbonate by the Solvay processĀ® were analyzedby different physico-chemical methods. Calcium carbonate was found as the main component ofboth the solid wastes. Trace amounts of other elements such as Mg, Al, Fe, Si, Cl, Na etc. werealso present in these wastes. These solid wastes showed higher sorption activity for the removalof H2S, compared to a pure commercial calcium carbonate. The contact time was found as animportant parameter for the complete H2S uptake. The addition of well-dispersed iron-basedparticles could be carried out by the standard incipient wetness impregnation method. Sorbentcontaining 1 wt.% of spiked iron had the similar sorption behavior compared to a commercialactivated carbon, in terms of reactivity and reactivation possibility.
