Abstract
The invention relates to a mineral desulfurizing agent (10), comprising calcium-based porous granules (12) which comprise a core (14) containing at least 80% by weight of calcium carbonate (CaCO3) and at least one agglomeration layer (16) enclosing the core (14) and containing calcium hydroxide (Ca(OH)2), wherein the granules (12) comprise a proportion of calcium hydroxide (Ca(OH)2) of at least 60% by weight, relative to the total dry weight of the granules (12), have an essentially spherical shape and a BET surface area of at least 8 m2/g. The invention further relates to a method for the production and to the use of a mineral desulfurizing agent.
