Book Description
This volume constitutes the proceedings of the second symposium on Catalysis and Automotive Pollution Control. CAPoC 2 was a great success from the point of view of its scientific interest, as evidenced by the content of this book, and also from the high participation, some 260 scientists. About two-thirds of the contributors came from the industrial world, mainly the car and oil industries and catalyst manufacturers. This is ample proof that exhaust catalysis remains a major topic of interest. The first part of the book is a general introduction to the problem of automotive pollution. The second, strictly catalytic, part is devoted to fundamental and applied studies on pollution control, with emphasis on exhaust catalytic converters.

Pages : 521
Book Description
In June 1984 the EEC Commission proposed new standards of permissible exhaust gas from motor vehicles to be introduced in Europe; these standards were approved by the Ministers of the Environment one year later. As the control of automotive pollution is at present mainly a catalytic problem, it was decided to hold an International Symposium on the subject, and an organizing committee composed of people engaged in catalytic research in the different Belgian Universities was constituted. This was the first Symposium of its kind to be held on an international level, and the quality and scientific interest of the papers presented was exceptional. It is planned to hold a follow-up Symposium in 2 to 3 years' time.The first part of the book is a general introduction to the problem of automotive pollution. The second, properly catalytic, part is devoted to fundamental and applied studies on pollution control, with emphasis on exhaust catalytic converters.

Catalysis and Automotive Pollution Control IV
Author: N. Kruse
Publisher: Elsevier
ISBN: 0080528619
Category : Technology & Engineering
Languages : en
Pages : 719
Book Description
In spite of the energy crises and the recession, there has been a global, explosive growth in the amount of motor vehicles. In the past 50 years, the amount has increased from 50 to 700 million vehicles. For economical reasons they will probably continue to be used for a considerable number of years, despite the poor yield of internal combustion engines resulting in the inevitable production of some gaseous pollutants. The subsequent increase of gaseous pollutants in our atmosphere caused by exhaust gas from automobiles has enhanced the problem of the elimination of these pollutants produced by internal combustion engines. Catalysis has proven to be the best solution to lower the content of exhaust gas in pollutants.As its predecessors, CAPoC4 proved to be a suitable platform for discussing technological improvements and developments along with future perspectives and challenges. In the light of new results and further legislative regulations, the following topics were intensely discussed: *low light-off behaviour based on improved catalysts and substrate formulations *efficient adsorber systems for storage of hydrocarbon emissions *electrically heated catalyst systems ahead the main catalyst or, alternatively, close coupled catalysts (at the manifold of the engine) • lean DeNOx catalysts allowing for decomposition of NOx in the oxygen-rich exhaust of direct injection gasoline engines and high speed injection diesel engines or, alternatively, NOx trapping/reduction in a hybrid approach * collection and destruction of dry particulates or soot.There is no doubt that clean vehicle technology is a vital part of improving air quality. Challenges remain and call for technological answers. Catalytic air pollution control is still an area providing a considerable incentive for innovative work.

Methods for Monitoring and Diagnosing the Efficiency of Catalytic Converters
Author: M. Sideris
Publisher: Elsevier
ISBN: 0080536492
Category : Technology & Engineering
Languages : en
Pages : 465
Book Description
The dramatic evolution of catalytic converters in the last thirty years was a result of a need worldwide to reduce pollution created by the exhaust gases of internal combustion engines. Environmental concerns have led American, Japanese and European Union (EU) legislation to pose continuously stricter emission limits for petrol engines in the last decades. The catalytic converter has become the most important means of exhaust treatment to achieve the desired emission limits. The international legislation has also created a need for a regular assessment of the efficiency of the catalytic converter in order to detect a deterioration of its conversion efficiency as soon as this deterioration takes place. The assessment of conversion efficiency of a catalytic converter can take place during normal driving of a vehicle (on-board diagnosis or OBD) or in a workshop by specialized technicians. The most important methods nowadays are the OBD methods. The evolution of methods concerned with OBD and non-OBD monitoring and diagnosing of efficiency of catalytic converters of internal combustion engines is described based on patents and published patent applications. Non-patent references are also used. The basic principles of modern catalytic converters are described in an extensive Introduction, where the importance of monitoring and diagnosing the efficiency of catalytic converters is demonstrated. The book is divided into four parts. The first part describes methods involving the use of oxygen or air/fuel exhaust gas sensors to determine the oxygen storage capacity of a catalytic converter. The second part describes methods involving the use of temperature sensors to determine the exothermic reaction capacity of a catalytic converter. The third part describes all other methods existing in patent literature that monitor and diagnose the efficiency of catalytic converters. The great majority of the methods of the third part involves exhaust gas concentration measurements. The fourth part comprises a general discussion of all methods described. In the beginning of each part, a short introduction is given to explain the problem that the methods attempt to solve. The methods in each part are presented in chronological order per patent applicant. This helps to evaluate how the patent applicant has improved his methods over time. A patent number index with information about the patent applicants, inventors, priorities and patent-families, an inventor index, a company index and a subject index can be found at the end of the book.

Experiments in Catalytic Reaction Engineering
Author: J.M. Berty
Publisher: Elsevier
ISBN: 0080531423
Category : Technology & Engineering
Languages : en
Pages : 289
Book Description
The science of catalytic reaction engineering studies the catalyst and the catalytic process in the laboratory in order to predict how they will perform in production-scale reactors. Surprises are to be avoided in the scaleup of industrial processes. The laboratory results must account for flow, heat and mass transfer influences on reaction rate to be useful for scaleup. Calculated performance based on these results must also be useful to maximization of profit and safety and minimization of pollution. To this end, information on products as well as byproducts and heat produced must be generated. If a sufficiently large database of knowledge is produced, optimization studies will be possible later if economic conditions change.The field of reaction engineering required new tools. For kinetic and catalyst testing, the most successful of these tools was the internal recycle reactor. Studies in recycle reactors can be made under well-defined conditions of flow and associated transfer processes, and close to commercial operation. The recycle reactor eliminates or minimizes the effect of transfer process, and allows the remaining ones to be known.Features of this book:• Provides insight into a field that is neither well understood nor properly appreciated.• Gives a deeper understanding of reaction engineering practice.• Helps avoid frustration and disappointment in industrial research. This book is short and clear enough to assist all members of the R&D and Engineering team, whether reaction engineers, or specialists in other fields. This is critical in this new age of computation and communication, when team members must each know at least something of their colleagues' fields. Additionally, many scientists in more exploratory or fundamental fields can use recycle reactors to study basic phenomena free of transfer interactions.

Zeolites: A Refined Tool for Designing Catalytic Sites
Author: L. Bonneviot
Publisher: Elsevier
ISBN: 008054469X
Category : Technology & Engineering
Languages : en
Pages : 585
Book Description
Formerly, the catalytic use of zeolites was exclusive to the field of acid catalysis. Nowadays, zeolites also find applications as catalysts in a wide array of chemical reactions such as; base catalyzed reactions, Redox reactions and catalytic reactions on transition metals and their complexes in confined environments. The concepts of Brønsted or Lewis acid-base pairs are adequately illustrated in the literature and well-understood in terms of structural and electronic properties of zeolites. By contrast, properties of chemically modified silicates, aluminosilicates and aluminophosphates have not yet been fully explored. The list of oxydo-reduction reactions performed in the presence of these new materials is growing as demonstrated by the selective catalytic reduction of nitrogen oxides or the numerous oxidations employing hydrogen peroxide. Much effort is currently being made to get a better insight into the nature of the sites involved. The zeolite lattice may also be used as a host for encapsulated complexes or metallic clusters allowing the control of nuclearity of these active species and the steric constraints imposed on the reactants. Molecular sieve and shape selectivity effects have also constituted fascinating aspects of zeolite properties. Recent developments leading to increasingly large pore sizes with VPI-5, cloverite and more recently mesoporous molecular sieves have broadened the spectrum of these applications. Indeed, larger and larger reactant and product molecules can be accommodated in these lattices. These new adsorbant/adsorbate systems create additional needs for experimental data and theoretical descriptions of transport properties, in particular of mono- and multi-components diffusion coefficients in the zeolite pore lattice.All these themes, representing the forefront and current trends in zeolite research, were discussed in the submitted papers to the symposium and are widely represented in the selected papers contained in this volume. A feature common to most of these contributions is the combined use of a variety of analytical techniques. Some of these techniques are at the frontier of the latest analytical developments such as multiple scattering EXAFS and bidimensional MAS-NMR.

ISBN: 0080965296
Category : Science
Languages : en
Pages : 7694
Book Description
Comprehensive Inorganic Chemistry II, Nine Volume Set reviews and examines topics of relevance to today’s inorganic chemists. Covering more interdisciplinary and high impact areas, Comprehensive Inorganic Chemistry II includes biological inorganic chemistry, solid state chemistry, materials chemistry, and nanoscience. The work is designed to follow on, with a different viewpoint and format, from our 1973 work, Comprehensive Inorganic Chemistry, edited by Bailar, Emeléus, Nyholm, and Trotman-Dickenson, which has received over 2,000 citations. The new work will also complement other recent Elsevier works in this area, Comprehensive Coordination Chemistry and Comprehensive Organometallic Chemistry, to form a trio of works covering the whole of modern inorganic chemistry. Chapters are designed to provide a valuable, long-standing scientific resource for both advanced students new to an area and researchers who need further background or answers to a particular problem on the elements, their compounds, or applications. Chapters are written by teams of leading experts, under the guidance of the Volume Editors and the Editors-in-Chief. The articles are written at a level that allows undergraduate students to understand the material, while providing active researchers with a ready reference resource for information in the field. The chapters will not provide basic data on the elements, which is available from many sources (and the original work), but instead concentrate on applications of the elements and their compounds. Provides a comprehensive review which serves to put many advances in perspective and allows the reader to make connections to related fields, such as: biological inorganic chemistry, materials chemistry, solid state chemistry and nanoscience Inorganic chemistry is rapidly developing, which brings about the need for a reference resource such as this that summarise recent developments and simultaneously provide background information Forms the new definitive source for researchers interested in elements and their applications; completely replacing the highly cited first edition, which published in 1973
