Books by Keyword: Zeolites

Description:

The Monte Carlo method, largely the brainchild of Stanislaw Ulam and first implemented by John von Neumann, depends upon the use of digital computers and is therefore very much a product of post-WW2 technological developments; even though one could argue that the Buffon’s Needle estimate was an ancestor of the technique. The probabilistic nature of the method makes it a good choice for modeling those physical phenomena which involve similarly random motions at the atomic scale; a particularly good example being that of mass diffusion. The present volume comprises a compilation of selected Monte Carlo studies of diffusion in borides, carbides, diamond, graphene, graphite, hydrides, ice, metals, oxides, semiconductors, sulfides, zeolites and other materials. General aspects of diffusion are also covered. The 516 entries cover the period from 1966 to 2014.

Description: The microporous aluminosilicate minerals known as Zeolites are invaluable as adsorbents, molecular sieves and catalysts because they possess a porous structure that can let pass or accommodate cations such as, Ca2+, K+, Mg2+, Na+, etc. These are nevertheless loosely held and can be easily exchanged for those in an adjacent solution. Movement of other materials through Zeolites is naturally an important factor. The present compilation consists of diffusion data. These represent, as far as possible, pure diffusion, shorn of other transfer mechanisms such as permeation. Most of the results involve well-known artificially produced Zeolites, but also include information on naturally occurring Zeolites such as analcime and clinoptilolite. The 290 entries, 22 figures and 67 tables cover the period from 1961 to 2014.

Description: From being mere geological curiosities one hundred years ago, zeolites have progressed to their present status as indispensable absorbents and catalysts both in key oil- refining process technologies and consumer detergent industries - to mention only two. As new families are synthesized, modern structural methods increase our understanding of their formation, structure and function. Furthermore, as new industrial uses have been found, the literature on zeolites, and on related zeotypes, has also grown - particularly over the past decade. Consequently, it is now a truism that one cannot review the subject of zeolites without being considerably selective.

Description: Membranes are playing a central role in a great variety of technological processes. Due to their physical and chemical properties the new classes of inorganic and organic polymer membranes play an ever increasing role in many applications.
