Effects of Moisture on Warming of Activated Carbon Bed during VOC Adsorption
TL;DR: In this article, the effect of the initial VOC concentration and the initial water content of the activated carbon (0.9.8%), and the volatile organic compound (VOC) concentration (0 −50 g⋅m−3) on the thermal amplitude of organic vapor was investigated.

Dynamics of non-isothermal adsorption in packed bed of biporous zeolites
TL;DR: In this paper, a two-dimensional mathematical model for description of non-isothermal adsorption was developed, including the effects of the radial temperature gradients, and good agreement is shown between experimental and theoretical results, when the mathematical model accounts for the radial thermal conduction and thermal flow through the wall.

Numerical study of nitrogen desorption by rapid oxygen purge for a medical oxygen concentrator
TL;DR: In this article, the purge gas quantity required for a specific desorption duty (fraction of total N2 removed from a column) is minimum when the process is carried out under ideal, hypothetical conditions (isothermal, isobaric, and governed by local thermodynamic equilibrium).

Separation of dilute CO2-CH4 mixtures by adsorption on activated carbon
TL;DR: In this article, the adsorption separation process of diluted gas mixtures containing carbon dioxide and methane on activated carbon has been investigated and the breakthrough curves for both the adaption and desorption processes have been obtained using mixtures of one or two adsorbable components and one nonadsorbable.
