|Abstract: ||The specific application of activated carbons (AC) as adsorbents for gases and vapours depends on the properties of pollutants to be removed, but the performance of the AC depends on various properties. If their porosity is the main parameter in gas adsorption, the chemical nature of their surface plays a significant role in liquid phase interactions and in their usefulness as catalyst support materials. Of particularly interest are the AC containing heteroatoms, such as oxygen, hydrogen, phosphorus, sulphur and nitrogen. Generally, the AC containing various nitrogen groups,present more basic character and increased adsorption of acidic agents is expected. These AC
found widespread applications as adsorbents for hydrogen sulphide, sulphur dioxide, sulphur and carbon dioxide and as catalysts for selective oxidation of hydrogen sulphide.|
