Catalysis and Zeolites by Jens Weitkamp,Lothar Puppe Pdf

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 (thanks to the pioneering work of R. M. Barrer and R. M. Milton) that this class of porous materials began to playa role in catalysis. A landmark event was the introduction of synthetic faujasites (zeolite X at first, zeolite Y slightly later) as catalysts in fluid catalytic cracking (FCC) of heavy petroleum distillates in 1962, one of the most important chemical processes with a worldwide capacity of the order of 500 million t/a. Compared to the previously used amorphous silica-alumina catalysts, the zeolites were not only orders of magnitude more active, which enabled drastic process engineering improvements to be made, but they also brought about a significant increase in the yield of the target product, viz. motor gasoline. With the huge FCC capacity worldwide, the added value of this yield enhancement is of the order of 10 billion US $ per year.

Handbook of Zeolites by T. W. Wong Pdf

Zeolites are microporous crystalline solids with well-defined structures. Generally they contain silicon, aluminium and oxygen in their framework and cations, water and/or other molecules within their pores. Many occur naturally as minerals, and are extensively mined in many parts of the world. Others are synthetic, and are made commercially for specific uses, or produced by research scientists trying to understand more about their chemistry. Because of their unique porous properties, zeolites are used in a variety of applications with a global market of several million tonnes per annum. In the western world, major uses are in petrochemical cracking, ion-exchange (water softening and purification), and in the separation and removal of gases and solvents. Other applications are in agriculture, animal husbandry and construction. They are often also referred to as molecular sieves. This book presents leading research from around the world.

Zeolites by B. Držaj,S. Hocevar,S. Pejovnik Pdf

The synthesis of zeolites with desired structure and properties is of great importance for the preparation of highly active and selective catalysts for inorganic and organic reactions. The zeolite matrix offers unique possibilities for carrying out molecular shape-selective catalysis and this places the zeolite matrices among the most successful tools used in molecular engineering on a large scale.These proceedings cover the most recent developments in the fields of synthesis, structure determination and technological use of zeolites. The papers give detailed explanations of the processes involved in the mechanisms of zeolite synthesis. Special attention is focussed on complex ionic equilibria which occur in the starting hydrogel, to the ``templating effect'' and to the kinetics of zeolite formation. New powerful methods for structure determination of these materials, which usually consist of small crystals, are presented e.g. neutron diffraction and X-ray diffraction using synchrotron radiation. The distribution of tetrahedrally coordinated framework-constituent elements and their interaction with adsorbates is revealed by using high magnetic field nuclear magnetic resonance with sample spinning at ``magic'' angle (MAS NMR).Quite a number of articles are devoted to the dependence of the physico-chemical properties of zeolites on the parameters set during their synthesis. Descriptions are given of the possible technological use of synthetic zeolites in the fields of adsorption, catalysis, the production of laundry detergents, the removal of radioactive wastes, and the technological use of natural zeolites in the fields of animal feeding, municipal water treatment, paper and cement production, and energy storage. This book will be of interest to scientists working in the fields of catalysis, surface science, inorganic chemistry, materials science, petrochemistry, solid state physics, crystallography and geology.

Natural Zeolites by David L. Bish,Douglas W. Ming Pdf

Volume 45 of Reviews in Mineralogy and Geochemistry is a new and expanded update of Volume 4 from 1977. Most of the material in this volume is entirely new, and Natural Zeolites: Occurrence, Properties, Applications presents a fresh and expanded look at many of the subjects contained in Volume 4. There has been an explosion in our knowledge of the crystal chemistry and structures of natural zeolites (Chapters 1 and 2), due in part to the now-common Rietveld method that allows treatment of powder diffraction data. Studies on the geochemistry of natural zeolites have also greatly increased, partly as a result of the interests related to the disposal of radioactive wastes, and Chapters 3, 4, 5, 13, and 14 detail the latest results in this important area. Until the latter part of the 20th century, zeolites were often looked upon as a geological curiosity, but they are now known to be widespread throughout the world in sedimentary and igneous deposits and in soils (Chapters 6-12). The application of natural zeolites has greatly expanded since the first zeolite volume. Chapter 15 details the use of natural zeolites for removal of ammonium ions, heavy metals, radioactive cations, and organic molecules from natural waters, wastewaters, and soils. Similarly, Chapter 16 describes the use of natural zeolites as building blocks and cements in the building industry, Chapter 17 outlines their use in solar energy storage, heating, and cooling applications, and Chapter 18 describes their use in a variety of agricultural applications, including as soil conditioners, slow-release fertilizers, soil-less substrates, carriers for insecticides and pesticides, and remediation agents in contaminated soils.

Zeolites: Advances in Research and Applications by Annett Mahler Pdf

Zeolite is a mineral that consists mainly of aluminosilicate, and its major commercial use is as a surfactant. Over the last decade, significant efforts have been devoted to the development of micro-mesoporous zeolite materials, which are also referred to as mesostructured zeolites. Zeolites show potential as heterogeneous catalysts for terpenes valorisation into fragrances and flavours, replacing the homogenous catalysts. The results of research on of zeolite catalysts for selective reduction of nitrogen oxides by C1-C4-hydrocarbons and ethanol are demonstrated, in particular, the selective reduction activity of Ag/BEA catalysts. The authors also explore the synthesis of hierarchical zeolites uzing green templates such as natural polymers, surfactants and biological agents, as traditional templates are expensive and toxic. The recent developments in dehydration of organics, organic/organic separation, desalination and gas separation using zeolite membranes are reviewed in detail. Studies on the synthesis of zeolites in alkali-activated materials and the physicochemical changes of alkali-activated materials induced by these zeolites are presented. Due to their stability, form selectivity, non-corrosiveness, and environmental compatibility, zeolites are suggested as a suitable option for the thermal catalytic cracking process. The authors provide fundamental research data on the Cuban zeolite in Detoxsan®, including its different medical applications in comparison to the available literature regarding the medical use of zeolites.
