Book excerpt: The kinetics of the Al/O2 reaction system has been studied with the AeroChem high-temperature fast-flow reactor (an adaptation of the steady-state flow reactor suitable for measurements at temperatures up to 2000K). The rate coefficient for the homogeneous gas-phase reaction Al + O2 to AlO + O has been determined. Evidence for a zero-order and a first order wall Al-oxidation process were also obtained. Comparison is made to other metal atom oxidations. (Modified author abstract).

Available in PDF, EPUB and Kindle. Book excerpt: Because of the need for quantitative information on gaseous metal atom oxidation kinetics, an experimental research program has been initiated to determine the mechanism and rate coefficients of the homogeneous reactions of free Fe and Al atoms with O2. The apparatus used is a cylindrical fast-flow reactor, adapted for the study of the kinetics of refractory gaseous species at temperatures up to 1900 K. The Fe/O2 reaction at 1600 K was investigated in N2/O2 flows by observing the rate of decay of Fe-atom concentrations, measured in absorption, at pressures from 15 to 60 Torr. The gas phase reaction has been determined to be Fe + O2 yields FeO + O, with a rate coefficient k sub 2=4 x 10 to the minus 13 power ml/molecule/sec. This result is estimated to be accurate to within a factor of about 2. Evidence for heterogeneous oxidation of Fe in the presence of O2 has also been obtained; the lower limit for the probability of Fe oxidation per collision with the reactor wall, is found to be on the order of 1/10.

Available in PDF, EPUB and Kindle. Book excerpt: The tubular fast-flow reactor, previously used for reaction kinetic measurements at temperatures up to only 1000K, has been adapted to reach temperatures up to 2000K and has been applied to studies of gas phase reactions of metal atoms with O2. The most extensive set of results obtained so far is for the Fe/O2 reaction in an N2 bath at 1600K. Preliminary results for the Al reaction with O2 at 1700K are discussed. The experimental technique described here allows measurements to be made under reaction conditions overlapping those used in flame and shock-tube studies. A design study for a wall-less reactor which would allow extension of metal atom oxidation studies down to about 200 to 300K is also reported. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: to the Fundamental and Applied Catalysis Series Catalysis is important academically and industrially. It plays an essential role in the manufacture of a wide range of products, from gasoline and plastics to fertilizers and herbicides, which would otherwise be unobtainable or prohibitively expensive. There are few chemical-or oil-based material items in modem society that do not depend in some way on a catalytic stage in their manufacture. Apart from manu facturing processes, catalysis is finding other important and ever-increasing uses; for example, successful applications of catalysis in the control of pollution and its use in environmental control are certain to increase in the future. The commercial importance of catalysis and the diverse intellectual challenges of catalytic phenomena have stimulated study by a broad spectrum of scientists, including chemists, physicists, chemical engineers, and material scientists. Increas ing research activity over the years has brought deeper levels of understanding, and these have been associated with a continually growing amount of published material. As recently as sixty years ago, Rideal and Taylor could still treat the subject comprehensively in a single volume, but by the 1950s Emmett required six volumes, and no conventional multivolume text could now cover the whole of catalysis in any depth. In view of this situation, we felt there was a need for a collection of monographs, each one of which would deal at an advanced level with a selected topic, so as to build a catalysis reference library.

This book was released on 2012-12-06 with total page 219 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents experimental data and recent results of model calculations on the formation of natural oxide film on metal surfaces and of metal hydride formation. Such films are responsible for corrosion, friction, and wear of metallic materials. Describing mostly the authors own research, this monograph gives an overview of models suitable for metal-gas reactions and demonstrates how complex metal-gas interactions can be analyzed by standard procedures of chemical kinetics. The book, and the data and equations it contains, will be useful to researchers in surface science, condensed-matter physics, and materials science.

Available in PDF, EPUB and Kindle. Book excerpt: Kinetic Studies in GeO2/Ge System: A Retrospective from 2021 investigates reaction kinetics in GeO2/Ge systems, aiming to demonstrate the fundamentals of the GeO2/Ge interface and to give insight into the distinctive features and performance of Ge (germanium) applied to advanced complementary metal oxide semiconductor (CMOS) devices. This book first reviews the development of MOS technology and discusses the potentials of emerging Ge and the challenges facing it as a contentious channel material, once promising to replace Si (silicon) for advanced nodes. The study systematically analyzes the following aspects of GeO2/Ge stacks that will shed light on the characteristics and reaction principles of the system: GeO2/Ge degradation, Ge passivation techniques, desorption kinetics of GeO from GeO2/Ge, the relationship between GeO2 crystallization and GeO2/Ge interface reaction, and the oxidation kinetics of Ge. Based on findings from the intrinsic properties of GeO2/Ge, the author also compares it with prevalent SiO2/Si systems and demonstrates the essential differences between the two, contributing to quality control, process optimization, and technology advancements of GeO2/Ge. The book will be a useful reference for researchers, professionals, and students interested in electronic materials, condenser matter physics, microelectronic engineering, and semiconductors.

Download or read book Kinetic Models of Catalytic Reactions written by G.S. Yablonskii and published by Elsevier. This book was released on 1991-04-17 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book has been written by a group of mathematicians and chemists whose common interest is in the complex dynamics of catalytic reactions. Based on developments in mathematical chemistry, a general theory is described that allows the investigation of the relationships between the kinetic characteristics of complex reactions and their detailed reaction mechanism. Furthermore, a comprehensive analysis is made of some typical mechanism of catalytic reactions, in particular for the oxidation of carbon monoxide on platinum metals. In fact, the book presents three kinetics: (a) detailed, oriented to the elucidation of a detailed reaction mechanism according to its kinetic laws; (b) applied, with the aim of obtaining kinetic relationships for the further design of chemical reactors; and (c) mathematical kinetics whose purpose is the analysis of mathematical models for heterogeneous catalytic reactions taking place under steady- or unsteady-state conditions.

Available in PDF, EPUB and Kindle. Book excerpt: Chemical processes in many fields of science and technology, including combustion, atmospheric chemistry, environmental modelling, process engineering, and systems biology, can be described by detailed reaction mechanisms consisting of numerous reaction steps. This book describes methods for the analysis of reaction mechanisms that are applicable in all these fields. Topics addressed include: how sensitivity and uncertainty analyses allow the calculation of the overall uncertainty of simulation results and the identification of the most important input parameters, the ways in which mechanisms can be reduced without losing important kinetic and dynamic detail, and the application of reduced models for more accurate engineering optimizations. This monograph is invaluable for researchers and engineers dealing with detailed reaction mechanisms, but is also useful for graduate students of related courses in chemistry, mechanical engineering, energy and environmental science and biology.
