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 Surface Oxygen Groups on Irreversible Adsorption of Volatile Organic Compounds on Beaded Activated Carbon
DownloadSpring 2017
Adsorption by activated carbons is a widely used method for controlling emission of volatile organic compounds (VOCs). However, accumulation of adsorbates and/or regeneration by-products (heel buildup) during cyclic process is a common challenge in this process. Irreversible adsorption restricts...
