Zeolites occur in nature and have been known for almost 250 years as alumino silicate minerals. Examples are clinoptilolite, mordenite, offretite, ferrierite, erionite and chabazite. Today, most of these and many other zeolites are of great interest in heterogeneous catalysis, yet their naturally occurring forms are of limited value as catalysts because nature has not optimized their properties for catalytic applications and the naturally occurring zeolites almost always contain undesired impurity phases. It was only with the advent of synthetic zeolites in the period from about 1948 to 1959...

Molecular Sieves- Science and Technology will cover, in a comprehensive manner, the science and technology of zeolites and all related microporous and mesoporous materials. Authored by renowned experts, the contributions will be grouped together topically in such a way that each volume of the book series will be dealing with a specific sub-field. Volume 3 deals with the most widely employed techniques for the post-synthesis modificaton of molecular sieves. Among the topics covered in considerable detail are ion exchange, both in the more conventional variant in aqueous suspension and in the...
