Importance of spectroscopic and static gravimetric studies for exploring adsorption behavior of propan-2-ol vapor in a fixed-bed column

Adsorption behaviour of polar solvent and water vapours on Sorbonorit B4 activated carbon

“…As shown in Fig. 5, the C ps value increases with increasing temperature up to 60 o C, then it is almost constant up to 100 o C. An increase in temperature to 200 o C caused an increase in the C ps value from 0.9 to 1.24 J/g K. The following fourth-order polynomial equation was used to correlate the experimental data: (9) The relative error of approximation δ was 1.5%. high concentrations of adsorbate in the air, the increase in bed temperature may be so large that the process cannot be treated as isothermal, which should be taken into account when designing the fi xed-bed adsorber.…”

“…Regeneration conditions should be optimized to enable rapid desorption with minimal adsorbate decomposition and coke formation. Due to heel formation, some adsorptive sites remain occupied by the adsorbate, which caused a change in the surface chemistry and adsorption capacity of AC 7- 9 . Insuffi cient regeneration effi ciency of the adsorbent in a given adsorption cycle shortens the adsorption time in the subsequent cycle 7, 10 .…”
