This book was released on 2018 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Respiratory protective equipment is recommended as one method to diminish exposure to airborne pollutants, including volatile organic compounds (VOCs). Activated carbon fiber (ACF) has a potential use as an alternative adsorbent in respirators for VOCs. The advantages of ACF as an alternative absorbent include larger surface areas, higher adsorption capacities, thinner critical bed depth, higher number of micropores, faster heat and mass transfer properties, and its fabric form. When its saturation capacity is reached, the adsorbent is no longer effective for removing pollutants. To recover the ability to capture gaseous pollutants, carbon adsorbents typically are regenerated. The ACF's ability to be regenerated makes it a more cost effective, energy efficient and environmentally sustainable option to aid in certain purification processes. The purpose of this study was to investigate the effects of thermal regeneration on the adsorption characteristics of activated carbon fiber (ACF) in respirator cartridges for toluene and also to investigate the extent to which regeneration decreased the ACF's adsorption capacity and breakthrough time (BT). Results showed that the 10% and 50% BTs for the two tested ACF types (ACF 210 and ACF 605) were not significantly different (P = 0.06). However, the differences in 10% and 50% BT between the two toluene concentrations (200 and 500 ppm) were significant (P

Download or read book Adsorption by Virgin and Modified Activated Carbon Fibers written by Zaheer Shaikh and published by LAP Lambert Academic Publishing. This book was released on 2014-02 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: The important factors involved in the adsorption of aromatic compounds from aqueous solution by activated carbon, surface chemistry and porosity, were examined in this thesis. This was achieved by systematically investigating the adsorption of benzene, aniline, toluene, nitrobenzene and fluorobenzene by a granular activated carbon and various virgin and surface modified activated carbon fibers. The adsorption of water molecules (water vapor isotherms), the synthetic organic compound (SOC) itself (SOC vapor isotherms), and the SOC in water (i.e. SOC aqueous phase isotherms) on activated carbons were studied side by side.

This book was released on 2015 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
