Book excerpt: Supercritical water is used for enhancing porous properties of anthracite powder and three kinds of activated carbon: commercial activated carbon, activated carbon from waste tires and activated anthracite. Distilled water and hydrogen peroxide solution are used as a liquid medium in batch process supercritical water treatment. The experimental variables are treatment time, chemical (NaOH and KOH solution) pre-treatment and concentration of hydrogen peroxide solution. The results show that treatment time and chemical pre-treatment have little effect on the porous properties of the anthracite powder. In case of using distilled water as liquid medium, a slight increase in the surface area and mesopore volume is observed, while the micropore volume decreases. Moreover, the porous properties of activated carbon decrease while the concentration of hydrogen peroxide solution increases. However, it is clear that supercritical water treatment is not effective for improving porous properties of activated carbon. In liquid-phase adsorption and supercritical water regeneration studies, phenol and organic dye Red 31, are selected as the representative adsorbates. The steam activated anthracite powder is compared with a commercial activated carbon. The results indicate that the obtained activated anthracite shows comparable phenol adsorption capacity but much lower dye adsorption capacity than the commercial one. However, supercritical water regeneration efficiency is remarkably high. The first/second regeneration efficiency of commercial activated carbon and activated anthracite exhausted with phenol are 55/98 and 65/99% and in case of RED 31 are 78/100 and 338/93% with losses of activated carbon less than 4% per regeneration. Because of little losses of activated carbon and successive regeneration, this regeneration method is suitable for regenerating exhausted activated carbon.

Available in PDF, EPUB and Kindle. Book excerpt: This is the second volume on adsorption using green adsorbents and is written by international contributors who are the leading experts in the adsorption field. Together with the first volume they show a typical selection of green materials used in wastewater treatment, with emphasis on industrial effluents. This second volume focuses on innovative materials. It presents hemp-based materials for metal removal, and the use of leaves for metal removal. It describes the biosorption of metals and metalloids on various materials and discusses the recent advances in cellulose-based adsorbents used in environmental purposes. Furthermore, activated carbons from food wastes, aerogels and bones, and municipal solid waste biochar as efficient materials for pollutant removal, respectively are reviewed as well as biosorption of dyes onto microbial biosorbents and the use of mushroom biomass to remove pollutants are looked at. The volume also includes detailed review of green adsorbents for removal of antibiotics, pesticides and endocrine disruptors and the use of pillared interlayered clays as innovative materials for pollutant removal. Finally, the use of green adsorbents for radioactive pollutant removal from natural water is discussed. The audience for this book includes students, environmentalists, engineers, water scientists, civil and industrial personnel who wish to specialize in adsorption technology. Academically, this book will be of use to students in chemical and environmental engineering who wish to learn about adsorption and its fundamentals. It has also been compiled for practicing engineers who wish to know about recent developments on adsorbent materials in order to promote further research toward improving and developing newer adsorbents and processes for the efficient removal of pollutants from industrial effluents. It is hoped that the book will serve as a readable and useful presentation not only for undergraduate and postgraduate students but also for the water scientists and engineers and as a convenient reference handbook in the form of numerous recent examples and appended information.

This book was released on 2020 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: This article discusses the preparation and characterization of activated carbon by the combined method (combination of two methods of chemical activation by ZnCl 2 and physical CO 2 ) leads to essentially microporous coals with specific BET specific surfaces which can exceed 800 m 2 /g. It is generally obtained by the BET method which is based on the adsorption capacity (in vapor phase) of nitrogen at 77 K and the steric hindrance of the N2 molecule. Microporous activated carbon prepared from Moroccan red macroalgae can be used as excellent carriers for adsorbing small molecules like heavy metals and other organic molecules like pesticides. This work was devoted to the characterization of active carbon prepared from red macroalgae with H 3 PO 4 , ZnCl 2 , CO 2 , H 3 PO 4 / CO 2 , ZnCl 2 / by TFIR, BET and SEM.

Book excerpt: Activated carbons have been found a large variety of applications in several fields, such as chromatography, medicine, gas storage and environmental protection, among others. Most of these applications requires tailored physical-chemistry properties, regarding purity, particles shape, mechanical resistance, homogeneity, surface composition, specific surface area and porosity. Because of their especial properties, activated carbons have attracted increasing attention for several years. As supports and catalysts, they have been used in several reactions both in gas and liquid phases, such as hydrogenation/dehydrogenation, oxidation/reduction, decomposition of hydrocarbons, halogenation and methanation, among others. This book reviews the applications, preparation, properties synthesis, and uses of activated carbon.

Book Synopsis Synthesis and Characterization of Chemically Treated Activated Carbons for Adsorption of Trace Contaminants by : Christian Lincoln Mangun
Download or read book Synthesis and Characterization of Chemically Treated Activated Carbons for Adsorption of Trace Contaminants written by Christian Lincoln Mangun and published by . This book was released on 1997 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the undesirable features of the modern day world is widespread contamination associated with the release of a large number of chemicals into the environment. In recent years there has been a tremendous amount of work done to quantify the harmful effect of these trace contaminants. Society's growing concern has led many governments to establish stricter standards for clean air and water, many of them in the ppb range. This necessitates the development of greatly improved methods for controlling the release of toxic contaminants and on designing new materials tailored to selectively remove a wide range of contaminants and permit for recovery and reuse. One technology which is extremely attractive for this purpose is the use of dry adsorbents such as activated carbons. Activated carbons have been used for many years for both air and water purification through a physical adsorption process in the micropores. Activated carbon granules (ACG's) have been the industry standard for many years. They are used as adsorbents to purify polluted waste streams because of their low cost and because they have been determined to be the best available technology for removal of many contaminants. However, the ACG's suffer from a number of drawbacks including poor selectivity, slow kinetics, the need for expensive containment systems, less than 100% working capacity, and costly reactivation. Perhaps the most serious problem is the absence of a comprehensive understanding as to the effect of pore size and chemistry on the adsorption properties. Such knowledge would allow one to tailor activated carbons for control of specific contaminants. There is a definite need for the development of improved materials designed specifically for a wide range of environmental problems.
