Adsorption-Induced and Thermal Deformation of Microporous Carbon Adsorbent upon n-Octane Adsorption
Relative linear adsorption-induced deformation of granules of AR-V microporous carbon adsorbent has been measured upon n -octane adsorption at pressures p of 1 Pa to 1.6 kPa and temperatures T = 273, 293, 313, 353, and 393 K. At p > 200 Pa, the adsorption-induced deformation is positive and grows...

| description | Relative linear adsorption-induced deformation of granules of AR-V microporous carbon adsorbent has been measured upon
n
-octane adsorption at pressures
p
of 1 Pa to 1.6 kPa and temperatures
T
= 273, 293, 313, 353, and 393 K. At
p
> 200 Pa, the adsorption-induced deformation is positive and grows with
p
throughout the considered temperature range. Under isobaric conditions, the adsorption-induced deformation and the slope of deformation isotherms increase as
T
decreases. At
p
< 200 Pa and
T
< 350 K, the adsorption-induced deformation is negative. The range of adsorbent contraction narrows with an increase in
T
, and, at
T
> 350 K, the adsorbent expands throughout the pressure range. Molecular dynamics simulation has been employed to study the structure of
n
-octane adsorption associates in model slit-like micropores having a width corresponding to the effective size of micropores in AR-V adsorbent calculated in terms of the theory of volume filling of micropores. The structure of the adsorption associates has been related to the characteristic features of the adsorption-induced deformation of AR-V adsorbent. |
