Book Synopsis Unsteady State Processes in Catalysis by : Yu S. Matros
Download or read book Unsteady State Processes in Catalysis written by Yu S. Matros and published by VSP. This book was released on 1990-12 with total page 728 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last decades the investigation methods of unsteady state catalytic processes have been widely developed by the response-technique methods. From this research emerged the realization that under unsteady state conditions and, especially under artificially created ones, it is possible to increase the productivity or selectivity of a catalyst or a catalytical process as a whole. The scientific literature in this field is mostly theoretical and aims at structuring and analysing mathematical models of unsteady state catalytical processes. In this book the theoretical and applied aspects of an efficiency of artificially created unsteady conditions in catalysis are discussed. It contains the lectures from researchers from all over the world that were held during the International Conference ''Unsteady State Processes in Catalysis'', 5--8 June 1990, Novosibirsk (USSR). Topics include: -- The problems of dynamics of a catalyst surface -- Kinetic models of unsteady processes -- Dynamics of chemical reactors -- Artificially created unsteady processes in a catalytic reactor.

Available in PDF, EPUB and Kindle. Book excerpt: Nonequilibrium Processes in Catalysis presents modern ideas and experimental data (e.g., molecular beams, laser technique) on adsorption and catalysis, the mechanism of energy exchange in the processes of particles interaction with a surface, and the lifetimes of excited particles on a surface. Previously unpublished theoretical information regarding the principle of chemoenergetical stimulation accounting for the acceleration of one reaction at the expense of reactant excitation in another is provided, and new ideas about nonequilibrium surface diffusion are explored. Examples of the formation of nonequilibrium dissipative structures in catalysis are presented, including auto-oscillations, auto-waves, multiplicity of kinetic regimes, nonequilibrium phase transition, and decelerated electron exchange between solid and adsorbed species. The book also describes new experimental methods for studying nonequilibrium and quick processes in catalysis. Nonequilibrium Processes in Catalysis will benefit physicists involved with surface science, chemists involved with adsorption and catalysis, engineers, vacuum scientists, physical chemists, materials chemists, students, and others interested in these processes.

Book Synopsis Reaction Kinetics and the Development and Operation of Catalytic Processes by : G.F. Froment
Download or read book Reaction Kinetics and the Development and Operation of Catalytic Processes written by G.F. Froment and published by Elsevier. This book was released on 2001-04-03 with total page 663 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reaction Kinetics and the Development and Operation of Catalytic Processes is a trendsetter. The Keynote Lectures have been authored by top scientists and cover a broad range of topics like fundamental aspects of surface chemistry, in particular dynamics and spillover, the modeling of reaction mechanisms, with special focus on the importance of transient experimentation and the application of kinetics in reactor design. Fundamental and applied kinetic studies are well represented. More than half of these deal with transient kinetics, a new trend made possible by recent sophisticated experimental equipment and the awareness that transient experimentation provides more information and insight into the microphenomena occurring on the catalyst surface than steady state techniques. The trend is not limited to purely kinetic studies since the great majority of the papers dealing with reactors also focus on transients and even deliberate transient operation. It is to be expected that this trend will continue and amplify as the community becomes more aware of the predictive potential of fundamental kinetics when combined with detailed realistic modeling of the reactor operation.
Book Synopsis Dynamics of Surfaces and Reaction Kinetics in Heterogeneous Catalysis by : G.F. Froment
Download or read book Dynamics of Surfaces and Reaction Kinetics in Heterogeneous Catalysis written by G.F. Froment and published by Elsevier. This book was released on 1997-09-03 with total page 594 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many processes of the chemical industry are based upon heterogeneous catalysis. Two important items of these processes are the development of the catalyst itself and the design and optimization of the reactor. Both aspects would benefit from rigorous and accurate kinetic modeling, based upon information on the working catalyst gained from classical steady state experimentation, but also from studies using surface science techniques, from quantum chemical calculations providing more insight into possible reaction pathways and from transient experimentation dealing with reactions and reactors. This information is seldom combined into a kinetic model and into a quantitative description of the process. Generally the catalytic aspects are dealt with by chemists and by physicists, while the chemical engineers are called upon for mechanical aspects of the reactor design and its control. The symposium "Dynamics of Surfaces and Reaction Kinetics in Heterogeneous Catalysis" aims at illustrating a more global and concerted approach through a number of prestigious keynote lectures and severely screened oral and poster presentations.
Book Synopsis Introduction to Non-linear Kinetics in Heterogeneous Catalysis by : Yuri I. Pyatnitsky
Download or read book Introduction to Non-linear Kinetics in Heterogeneous Catalysis written by Yuri I. Pyatnitsky and published by Nova Publishers. This book was released on 2000 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book comprises seven chapters. The first chapter addresses a phenomenological approach to the concept 'reaction rate', which views the complex reaction as a single unit whose progress if judged from measurements of the formation rates of the reaction participants; it also sets forth the main strategies by which to determine the rates of heterogeneous catalytic reactions. Another approach, a mechanistic one, relying upon the reaction mechanisms considered in the second chapter that has recourse to the Horiuti-Temkin complex reaction kinetics theory and the elementary statement of the graph method application in chemical kinetics. The third, fourth and fifth chapters consistently expound the philosophy of the steady state multiplicity, auto-oscillations, and the reciprocal effect of competitive catalytic reactions. The sixth and seventh chapters concentrate on the kinetics of some pragmatically important heterogeneous and heterogeneous-homogeneous catalytic reactions. Most results, presented in these chapters were obtained in the authors' laboratories.

Book Synopsis Reaction Engineering for Pollution Prevention by : R.P. Hesketh
Download or read book Reaction Engineering for Pollution Prevention written by R.P. Hesketh and published by Elsevier. This book was released on 2000-02-09 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book defines environmental reaction engineering principles, including reactor design, for the development of processes that provide an environmental benefit. With regard to pollution prevention, the focus is primarily on new reaction and reactor technologies that minimize the production of undesirable side-products (pollutants), but the use of reaction engineering as a means of treating wastes that are produced through other means is also considered. First is a section on environmentally benign combustion. The three papers discuss methods of reducing the formation of PAHs and NOx, as well as other environmentally sensitive combustion products. The next section contains a collection of contributions that involve the use of a catalyst to support the reaction. Following this is a section on the use of supercritical fluid solvents as environmentally friendly media for chemical reactions. Finally, a series of papers is presented in which novel reactor designs are utilized to obtain product yields not possible in conventional reactor systems. These include the use of reactor-absorber systems, reactive distillation, and reactive membranes. The book concludes with a chapter contributed by the editors which discusses the educational aspects of pollution prevention. It is necessary for future generations of engineers to be trained to design processes that are inherently environmentally benign. This chapter assembles resource materials for educators which will spark the creative instincts of the researchers using the materials contained within this book to develop new resources for pollution prevention education. The broad spectrum of topics included in this book indicates the diversity of this area, and the vibrant nature of the ongoing research. The possibilities of producing desirable products without the formation of waste byproducts are bounded only by the creativity of the reaction engineer.
