Authored by an international team of renowned scientists, the seven chapters of this book present a comprehensive overview of the application of zeolites in industrial catalysis, while also providing a true scientific understanding of how zeolites are synthesized, modified and characterized, and providing special emphasis on shape-selective catalysis, which is a unique feature of zeolites.

Theoretical studies of zeolite catalysis. book in recent years there has been an increasing number of theoretical studies on the nature of the acid sites in zeolites 5, 6, the interactions of these acid sites with adsorbates including hydrocarbons 7, 8, and on simple reactions of hydrocarbon species using model systems to represent the zeolite 9, The most common approach has been.

Zeolites have been used as catalysts in industry since the early s. The great majority of commercial applications employ one of three zeolite types: zeolite Y (faujasite); mordenite; ZSM By far the largest use of zeolites is in catalytic cracking, and to a lesser extent in hydrocracking.

The gas-phase carbonylation of dimethoxymethane (DMM) to form methyl methoxyacetate (MMAc) can be catalyzed by acid zeolites. This reaction is a critical step in the synthesis of monoethylene glycol (MEG), a widely used chemical, from synthesis gas. The mechanism of DMM carbonylation occurring on H−MFI and H−FAU zeolites has been investigated using density functional theory.

Research efforts in zeolite catalysis have become increasingly cognizant of the diversity in structure and function resulting from the distribution of framework aluminum atoms, through emerging reports of catalytic phenomena that fall outside those recognizable.

[John B Moffat] -- Catalysis involves just about every field of scientific study. This means that a multidisciplinary approach is needed in catalytic studies. Catalysis involves breaking and forming new bonds and this. The use of a solid catalyst makes the separation and purification of the final products steps easier to implement in comparison to catalysis in homogeneous conditions.

However, the efficiency of the zeolite in the heterogeneous transesterification reaction of vegetable oil is not well-known yet and varies on the structure of the catalyst used. in a zeolite Y - based catalyst was marketed by Carbide as an isomerization catalyst [21].

In Mobil Oil introduced the use of synthetic zeolite X as a hydrocarbon cracking catalyst. In Grace described the fi rst modifi cation chemistry based on steaming zeolite Y to form an “ ultrastable ” Y.

This agrees with other reported studies on the selectivity of zeolite catalysts towards the para position for many instances of aromatic acylation [28,29]. The anisole conversion was found to be 40, 56, 76, 88, and 90%, with the product selectivity toward p-methoxypropiophenone be 66.

We have carried out an experimental and theoretical study of CHA-zeolite supported indium (In)–oxo clusters that promote CH 4 activation at room temperature. X-ray absorption fine structure (XAFS) measurements indicate the formation of multinuclear In–oxo clusters by the O 2 activation of the In(I)-exchanged CHA zeolite prepared through reductive solid-state ion exchange (RSSIE).

Theoretical calculations are used to isolate and quantify these specific effects, with the main focus on methylbenzenes in ZSM-5, as the archetypical MTOcatalyst. This review intends to give an overview of recent theoretical insights, which have proven to provide an. Heterogeneous catalysis is a fascinating and complex subject of utmost importance in the present day.

Its immense technological and economical importance and the inherent complexity of the catalytic phenomena have stimulated theoretical and experimental studies by a broad spectrum of scientists, including chemists, physicists, chemical engineers, and material scientists.

The aim of this book is to be a critical review in the field of zeolite deactivation and regeneration, by collecting a series of contributions by experts in the field which describe the factors, explain the techniques to study the causes and suggest methods to prevent (or limit) catalyst deactivation.
