Download or read book On the Activation of Asturian Anthracite Following Various Pretreatments written by and published by . This book was released on with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: An Asturian anthracite has been subjected to different pretreatments and subsequently activated by steam at 850°C to a total burn-off of 55 percent. The physical properties (micropore sizes and distributions, external surface areas, etc.) of the solids are compared with those of the carbon obtained by direct activation. Although the yield is generally low, it appears that better results are obtained by activation following preoxidation in air at 270°C for 3 days. In the case of pretreatments with a mixture of nitrogen, air, and water vapor at 450°C, the subsequent activation is less efficient. The micropore volumes and the pore size distributions are similar to those observed for soft precursors, but at a much lower degree of burn-off.

This book was released on 2003 with total page 240 pages. Available in PDF, EPUB and Kindle. 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.

Book excerpt: Kingston Steam Plant is located at the base of a peninsula formed by the Clinch and Emory River embayments of Watts Bar Lake about 2.7 miles above the confluence of the Clinch and Tennessee Rivers. The plant derives its name from Kingston, a small town of colorful history lying two miles to the south, which employs the distinction of being the capital of the State of Tennessee for one day, September 21, 1807.
Download or read book Chemistry of Ozone in Water and Wastewater Treatment written by Clemens von Sonntag and published by IWA Publishing. This book was released on 2012-08-31 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Even though ozone has been applied for a long time for disinfection and oxidation in water treatment, there is lack of critical information related to transformation of organic compounds. This has become more important in recent years, because there is considerable concern about the formation of potentially harmful degradation products as well as oxidation products from the reaction with the matrix components. In recent years, a wealth of information on the products that are formed has accumulated, and substantial progress in understanding mechanistic details of ozone reactions in aqueous solution has been made. Based on the latter, this may allow us to predict the products of as yet not studied systems and assist in evaluating toxic potentials in case certain classes are known to show such effects. Keeping this in mind, Chemistry of Ozone in Water and Wastewater Treatment: From Basic Principles to Applications discusses mechanistic details of ozone reactions as much as they are known to date and applies them to the large body of studies on micropollutant degradation (such as pharmaceuticals and endocrine disruptors) that is already available. Extensively quoting the literature and updating the available compilation of ozone rate constants gives the reader a text at hand on which his research can be based. Moreover, those that are responsible for planning or operation of ozonation steps in drinking water and wastewater treatment plants will find salient information in a compact form that otherwise is quite disperse. A critical compilation of rate constants for the various classes of compounds is given in each chapter, including all the recent publications. This is a very useful source of information for researchers and practitioners who need kinetic information on emerging contaminants. Furthermore, each chapter contains a large selection of examples of reaction mechanisms for the transformation of micropollutants such as pharmaceuticals, pesticides, fuel additives, solvents, taste and odor compounds, cyanotoxins.
