What property or structure of a gas is related to the selective absorption of gases by pressure swing adsorption adsorbents? ?
The atomic radius of a gas plays a role here; smaller atomic radii mean that, as pressure increases, the diffusion rate differs by many orders of magnitude. Gases with higher diffusion rates combine with the adsorbent
The atomic radius of a gas determines its diffusion rate; smaller atomic radii result in faster diffusion, and this effect becomes more pronounced as pressure increases. Gases with higher diffusion rates combine with the adsorbent, while the remaining gases are expelled
Physical adsorption: It is related to the molecular structure of the adsorbate. Chemical adsorption: It is related to the chemical structure of the adsorbate (groups, polarity). In many adsorption processes, both physical and chemical adsorption occur; however, it is necessary to determine which factor is the primary one
It is related to factors such as molecular size, diffusion radius, chemical structure, and ease of polarization; therefore, an analysis must be conducted for each specific gas and adsorbent.
