Book excerpt: This book presents a thorough review of the state-of-knowledge and recent innovations in the synthesis of pure and improved grades of fly ash zeolites (FAZ). Addressing improvements to conventional methods, it also showcases a novel technique for the synthesis of high cation exchangers from fly ash and detailed characterization techniques for the products obtained. In addition, it examines in detail various areas of specific applications of fly ash zeolites. Over the years, several methods such as hydrothermal, fusion prior to hydrothermal, microwave assisted hydrothermal and molten salt techniques for producing FAZ have been developed. However, one-step and two-step reactions between the fly ash and alkali usually generate alkaline wastes that may cause environmental contamination. In addition, the separation of FAZ from the partially activated fly ash (the impurities) remains a major concern for researchers and industrialists alike. /divIn view of these challenges, this book presents a novel technique for three-step activation (TSA), which focuses on recycling the fly ash-NaOH-water reaction by-products until zeolitic residue is formed. The FAZ (the final residue after third step reactions) synthesized in this manner exhibits exceptionally high cation exchange capacity, specific surface area and pore area. This book offers a comprehensive compendium of reading material on fly ash and its recycled product, the zeolites. Students at both undergraduate and graduate levels, researchers, and practicing engineers will all find this book to be a valuable guide in their respective fields.

This book was released on 2011 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coal fly ash (CFA) and aluminum dross are industrial wastes that required proper treatment and disposal. Several studies have been focusing on reusing CFA to produce zeolites; a porous crystalline materials with various applications. Nonetheless, the applicability of aluminum dross in zeolite synthesis has yet to be determined. In this study, CFA and aluminum dross were used for the synthesis of zeolite by akaline fusion. Aluminum oxide, a commonly used aluminum source, was also tested for comparison. Optimal condition of zeolite synthesis was determined based on characteristics of the products such as cation exchange capacity (CEC). Zeolite A was generated in this study. In the case of aluminum dross, optimal synthesis condition was obtained at 600 ̊C fusion temperature followed by crystallization at 80 ̊C. Although the observed CEC was relatively lower than those of the zeolites synthesized from aluminum oxide, their CEC values were still comparable. The cadmium and methylene blue (MB) adsorptions of the synthesized zeolites with high CEC values (P680, P780, D680, and D780) were then investigated. Among the three isotherm models including linear regression, Langmuir isotherm, and Freundlich isotherm, the data from cadmium adsorption by the synthesized zeolites fitted well with the Freundlich isotherm. On the contrary, MB adsorption could not be fitted with any models used in this study. These results suggest that zeolite A can be obtained from CFA and aluminum dross, and its capability in cadmium and MB removal was similar to the zeolite produced from aluminum oxide.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The generation of a large quantity of waste coal fly ash (CFA) via coal combustion process during power generation is of major concern as disposal of such huge quantity of fly ash causes serious threats to the environment. There is an exigent need to find out the proper solution for its disposal/utilization to reduce its harmful effects. The composition of waste coal fly ash mostly consists of silica and alumina. Hence, the researchers are tempted to utilize waste coal fly ash as a starting ingredient to make value-added materials like zeolites. It is anticipated that such research efforts will act as a valuable aid to reduce the disposal cost of fly ash and ultimately reduce harmful effects of fly ash to the environment. In this review, various synthesis methods to synthesize different types of zeolites from CFA, such as Zeolite-A, Zeolite-X and Zeolite-P, have been summarized and their potential for various applications such as sorption and catalysis has been explored.

Download or read book Circular Economy and Fly Ash Management written by Sadhan Kumar Ghosh and published by Springer Nature. This book was released on 2019-10-25 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a number of innovative uses of fly ash. Fly ash is a fine powder that is a byproduct of burning pulverized coal in thermal power plants. It is a pozzolan – a substance containing aluminous and siliceous material that when mixed with lime and water forms a compound similar to Portland cement. Though fly ash was a problem in terms of its disposal, it now has a variety of uses, such as a prime material in blocks, bricks, and PCC paving, and further applications are being investigated. As such, the recovery and reuse of fly ash wastes plays an important role in the implementation of the circular economy concept. Featuring selected, high-quality research papers presented at IconSWM 2018, the book provides valuable insights for the recycling industries, power plants, researchers, and governments.

Available in PDF, EPUB and Kindle. Book excerpt: From areport by a Lieutenant Colonel W.A. Ross (Chern. News, Nov.15, 1878, p. 236). Progress did not accelerate during the next 50 years. McBain, in his clas sic 1932 book, The Sorption oi Gases by So lids, devoted a chapter to sorp tion by chabasite, other zeolites, and permeable crystals. McBain remarked that "great interest attaches to the finding of Weigel and Steinhoff [0. Weigel and E. Steinhoff, Z. Kris!., 61, 125 (1925{raquo}) that chabasite rapidly sorbs the vapors of water, methyl and ethyl alcohol and formie acid, whereas acetone, ether and benzene are largely excluded. The significance of their results was pointed out by McBain [J.W. McBain, Colloid. Syrnp. Mon., 20, 1 (1926{raquo}) and recognized by alliater writers. It is evident that the partially dehydrated chabasite forms a nearly perfect molecular sieve or a semipermeable membrane of extremely regular structure ... ". While the significance of the above observation may have been recog nized, it had little impact. Thus, an eminent pioneer in the synthesis and characterization af zeolites, Professor R.M. Barrer, spent nearly two dec ades (following his Ph. D. studies in the 1930s) developing a firm foundation for the rapid growth in scientific understanding and industrial applications of zeolites which has taken place during the last 30 years.
