A novel concept of co-capture of CO₂ and H₂S in a gasifier-based process was also investigated. Unlike the findings for co-capture of SO₂ and CO₂, no obvious impeding effect of H₂S was observed on cyclic CO₂ capture. Parametric studies indicated that it should be feasible to co-capture H₂S and CO₂.

Effect of pressure and gas concentration on CO2 and SO2 ...

Therefore, both sul- phation and direct sulphation contribute to the production of CaSO4 and hence it is formed faster than at atmospheric pressure. In summary, for pressurized co-capture, free calcium is preferen- tially used for SO2 retention, and thus the CO2 capture capacity of the sorbent is reduced, even for the first cycle.
