PROBLEM TO BE SOLVED: To provide: hydrated lime which has a sufficiently large BET specific surface area and active ingredient content of hydrated lime, and COD of which is suppressed low; and a method for producing hydrated lime.SOLUTION: The hydrated slime is produced by a slaking process 4 where lime 1 and water 3 are reacted. A prescribed additive 2 to be used in the slaking process 4 is added, where the additive 2 comprises a material in which an organic compound having a hydroxyl group and an inorganic compound containing silicon dioxide are combined. Hydrated slime produced by using these additives can satisfy both of a low COD and a high BET specific surface area, and is suitably utilized as an acid gas remover and the like.SELECTED DRAWING: Figure 1 |
