Abstract
Nitrogen oxides removal method wherein nitrogen oxides are removed from a gas by bringing the gas into contact with a granulated material containing an alkali and cement material, active carbon and a binder. The active carbon promotes an absorption reaction between the alkali material and nitrogen oxides, the cement material provides a porous but strong structure to the material, and the binder permits longer use of the material in a wide range of conditions.
