General Several models do exist to define the adsorption process. For these calculations the Dubinin-theory is applied. The actual process conditions 3.2.1. The type of adsorbent can influence the equilibrium adsorption capacity in two ways. The total pore volume of the adsorbent.
Adsorption occurs by condensation of the adsorbate in the adsorbents pores.
A larger total pore volume will therefore result in a higher maximum amount of adsorbate being adsorbed. The pore size distribution of the adsorbent. The actual adsorption occurs almost only in the micropores. The macropores will determine the accessibility of the adsorbent, while the mesopores influence the transport of the adsorbate from the gas phase to the micropores. An adsorbent with a high activation degree, and therefore a high total pore volume, will possess a high maximum adsorption capacity.
