Abstract: | Adsorption dynamics of single and binary vapor systems on the activated carbon bed were studied by using acetone, methylethyketone
(MEK), benzene, and toluene. Relationships between the equilibrium adsorption capacity and the characteristics of vapors such
as molecular weight, density, boiling point, vapor pressure, molecular diameter, and polarity index were also investigated.
From breakthrough experiments, toluene had the strongest affinity with activated carbon in the single and binary vapor systems.
The shape of the breakthrough curves of vapor with higher affinity in the binary system was similar to that of the single
vapor. On the other hand, the vapor with lower affinity showed a roll-up phenomenon, but the level of roll-up became lower
and wider with the increase in fraction in the binary system. |
