摘要:
It is described 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. A sorbent composition in powder form, said sorbent thermally activated and a process for the preparation of said sorbent composition are also described.
