| Zusammenfassung: | The present invention relates to a method for controlling the emission of polluting substances in a gaseous effluent produced by a combustion process comprising at least the step of putting said gaseous effluent, at a temperature within the range of 800°C - 1400°C, in contact with a sorbent composition in powder form comprising at least calcium hydroxide (Ca(OH)2), magnesium hydroxide ((MgOH)2) and magnesium oxide (MgO), said sorbent having a specific surface. area (BET) greater than 20 m2/g. The present invention also relates to a sorbent composition in powder form, said sorbent thermally activated and a process for the preparation of said sorbent composition. |
