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.

In 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.
