Adsorbents are solids characterized by a high specific mass or volume surface area. There are a large number of homogeneous and heterogeneous active centers on the surface where free bonds are provided by the solid for the adsorption of adsorbate molecules. The high specific surface is mainly due to the internal surface of the adsorbent body, which consists of a macro-pore system and a particularly important micropore system with external excess. Pore sizes are commonly [Pg.291]

The pore size distribution characterizes the pore system and hence the specific surface and the adsorbate loading capacity of the adsorbent (measurement techniques to de- [Pg.291]
