Activated-carbon fiber-cloth (ACFC) has been investigated as an alternative adsorbent to remove volatile organic compounds (VOCs) and hazardous air pollutants (HAPs) from gas streams when compared to conventional granular activated carbons (GACs). ACFC has up to twice the adsorption capacity of GAC and is more suited to electrothermal regeneration.

Capture and recovery of hazardous air pollutants (HAPs) and volatile organic compounds (VOCs) from gas streams using physical adsorption onto activated carbon fiber cloth (ACFC) is demonstrated on the bench-scale. This system is regenerated electrothermally, by passing an electric current directly through the ACFC. The adsorbate desorbs from the ACFC, rapidly condenses on the inside walls of the adsorber, and then drains from the adsorber as a pure liquid. Rapid electrothermal desorption exhibits such unique characteristics as extremely low purge gas flow rate, rapid rate of ADFC heating, rapid mass transfer kinetics inherent to ACFC, and in-vessel condensation. An existing system was scaled up 500%, and the new system was modeled using material and energy balances. ... These results allow the modeling of electrothermal desorption of organic vapors from gas streams with in-vessel condensation to optimize operating conditions of the system during regeneration of the adsorbent.

Adsorption is the most common method for controlling volatile organic compounds (VOCs) emission from automotive painting process. However, unwanted accumulation of adsorbate during cycling (heel buildup) is a common challenge in this process. The objective of this research is to identify the impact of regeneration conditions such as temperature, heating rate and purge flow rate on heel buildup and adsorption capacity. For this purpose, five cycle adsorption/regeneration experiments using 1,2,4-trimethylbenzene (TMB) on activated carbon fiber cloth (ACFC) were completed using resistive heating. Increasing temperature from 288 to 400°C worsened adsorbent performance, as indicated by smaller adsorption capacity and larger heel buildup. Decreasing heating rate from 100 to 5°C/min and increasing flow rate from 5 to 0.1 SLPM decreased heel buildup (by 56% and 90%, respectively) and capacity loss (by 85% and 97%, respectively). These observations are the result of carbon deposition due to thermal degradation of TMB during regeneration which is the impact of rapid adsorbent heating rates. The results of this work will help to optimize regeneration condition to allow fast desorption with minimal adsorbate decomposition.
