Comments on 'Proposal for a Regenerative High-Temperature Process for Coal Gas Cleanup with Calcined Limestone'.
Original language description
A fundamental difference between the reaction of H2S with lime (CaO) and that with limestone (CaCO3) is the presence of an alkaline, highly developed porous texture in the reacting lime particles. In order to eliminate hindrance effect of carbon dioxideon the H2S fixation, temperature must be above the calcination temperature of CaCO3. The affinity between H2S and CaO is somewhat less than generally presumed. About 47% of CaS can be oxidized to CaSO4 due to the difference in molar volumes of CaSO4 andCaCO3.
