Effect of Desorption Purge Gas Oxygen Impurity on Heel Formation During Regeneration of Beaded Activated Carbon Saturated with Organic Vapors
DownloadFall 2017
Irreversible adsorption or heel formation during cyclic adsorption/regeneration of high molecular weight volatile organic compounds (VOCs) onto activated carbon decreases its adsorption capacity and lifetime. The effect of regeneration purge gas oxygen impurity on activated carbon performance,...

Effect of fluidization on adsorption of volatile organic compounds on beaded activated carbon
DownloadSpring 2014
Adsorption on activated carbon is a widely used technique for controlling emissions of volatile organic compounds (VOCs) from automotive painting booths; however, irreversible adsorption is a common challenge in this process. This research investigates the effect of adsorbent bed configuration on...

Two-Dimensional Modeling of the Effect of Relative Humidity on Volatile Organic Compounds Adsorption in a Fixed Bed Adsorber
DownloadFall 2017
Water vapor can affect adsorption of volatile organic compound (VOC) onto activated carbon. In this research, a two-dimensional heterogenous computational fluid dynamics model was developed and validated to understand the mechanism and kinetics during competitive adsorption between VOC and water...
