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 Purge Gas Flow Rate and Oxygen Impurity on Heel build-up and Prediction of Heel build-up Using Machine Learning
DownloadFall 2021
Heel buildup, i.e., the accumulation of non-desorbed/non-desorbable adsorbates and their by-products on an adsorbent, during cyclic adsorption/regeneration of volatile organic compounds (VOCs) onto activated carbon decreases its adsorption capacity and lifetime. In this this study, the effect of...

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...

Spring 2021
Oxygen presence during thermal desorption of volatile organic compounds (VOCs) from adsorbent can promote heel build-up and loss of adsorption capacity, which reduces the performance of adsorbent in a cyclic adsorption/desorption process. The heel build-up, in some cases, could be attributed to...

Plant litter: direct and indirect effects of simulated climate change and clipping on its decomposition, and its effects on plant-plant interactions
DownloadFall 2013
Terrestrial ecosystems are characterized by an intricate relationship between plants and soils that influence ecosystem and community level processes and properties. At the ecosystem level, plants (producers) provide organic carbon to the decomposer subsystem and obligate root-associated...

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...
