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

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.

Available in PDF, EPUB and Kindle. Book excerpt: "Phenols are classified to be one of the most hazardous pollutants found in wastewater. They are discharged into rivers, lakes and seas, causing adverse effects on the environmental and human health. Adsorption is a well-known technique used to treat wastewater. Activated carbon fibers (ACFs) are highly microporous efficient adsorbents due to their small diameters, high surface area and excellent volumetric capacity. In this work, ACFs were produced using polyacrylonitrile (PAN) fibers using different methods and tools. The fibers were stabilized initially at 250 °C followed by carbonization at 850°C at a heating rate of 10°C/min and under the flow of nitrogen gas at a flow rate of 135ml/min. The carbonized fibers were subjected to physical (carbon dioxide) and chemical (potassium hydroxide) activation. The results showed that chemical activation using 3:1 ratio of KOH(wt/wt) produced fibers with a higher surface area of 2885m2/g compared to the physically activated fibers (774m2/g). The synthesized ACFs (Syn-ACFs) were compared and characterized in terms of morphology, thermal stability, composition and pore characteristics using SEM, EDS, TGA, CHN and nitrogen isotherm (Quantachrome). Bench scale batch experiments were carried out to determine and compare the adsorption efficiency, optimum parameters and the capacity of Syn-ACF and commercial ACFs (C-ACFs) for p-cresol removal. The adsorption optimum conditions using Syn-ACFs are: Syn-ACFs dosage = 1 g/l, contact time = 30 minutes, temperature = 25°C and initial pH = 4.6. The adsorption study on (Syn-ACFs) gave a higher removal efficiency of 91.0% of p-cresol compared to 71.6% (C-ACFs) at a concentration of 350ppm. In addition, the adsorption isotherms of p-cresol on C-ACFs and Syn-ACFs were found to follow the Langmuir isotherm equation; however, Syn-ACFs revealed a higher adsorption capacity (500mg/g) compared to C-ACFs (294 mg/g) at 25°C.The Syn-ACFs regeneration method was evaluated thermally at elevated temperatures and chemically using ethanol and n-hexane solvents. The thermal regeneration at 600°C achieved a higher removal efficiency of 84% compared to n-hexane (78%). The Syn-ACFs were evaluated for the treatment of produced water to ensure a removal of 71.2%. The results indicated that Syn-ACFs could be used as an efficient adsorbent for p-cresol removal in wastewater."--Abstract.

Book excerpt: Following in the lineage of Adsorption by Carbons (Bottani & Tascon, 2008), this work explores current research within contemporary novel carbon adsorbents. Both basic and applied aspects are discussed for this important class of materials. The first section of the book introduces physical adsorption and carbonaceous materials, and is followed by a section concerning the fundamentals of adsorption by carbons. This leads to development of a series of theoretical concepts that serve as an introduction to the following section in which adsorption is mainly envisaged as a tool to characterize the porous texture and surface chemistry of carbons. Particular attention is paid to novel nanocarbons, and the electrochemistry of adsorption by carbons is also addressed. Finally, several important technological applications of gas and liquid adsorption by carbons in areas such as environmental protection and energy storage constitute the last section of the book. - Encompasses fundamental science of adsorption by carbons, in one location, supporting current R&D without extensive literature review - Describes adsorption as it is currently applied to major novel types of carbon materials, including carbon gels, carbide-derived carbons, zeolite-templated carbvons, hydrothermal carbons, carbon nanohorns and graphene - Specific discussion of fuel storage, environmental remediation and biomedical applications, of contemporary interest to many surface chemists and applications-focused researchers

This book was released on 1998-09-22 with total page 915 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers topics of equilibria and kinetics of adsorption in porous media. Fundamental equilibria and kinetics are dealt with for homogeneous as well as heterogeneous particles. Five chapters of the book deal with equilibria and eight chapters deal with kinetics. Single component as well as multicomponent systems are discussed. In kinetics analysis, we deal with the various mass transport processes and their interactions inside a porous particle. Conventional approaches as well as the new approach using Maxwell-Stefan equations are presented. Various methods to measure diffusivity, such as the Differential Adsorption Bed (DAB), the time lag, the diffusion cell, chromatography, and the batch adsorber methods are also covered by the book. It can be used by lecturers and engineers who wish to carry out research in adsorption. A number of programming codes written in MatLab language are included so that readers can use them directly to better understand the behavior of single and multicomponent adsorption systems.
