Gas-Solid Reactions PDF Author: Julian Szekely
Publisher: Elsevier
ISBN: 0323151396
Category : Science
Languages : en
Pages : 415

Book Description
Gas-Solid Reactions describes gas-solid reaction systems, focusing on the four phenomena—external mass transfer, pore diffusion, adsorption/desorption, and chemical reaction. This book consists of eight chapters. After the introduction provided in Chapter 1, the basic components of gas-solid reactions are reviewed in Chapter 2. Chapter 3 describes the reactions of individual nonporous solid particles, while Chapter 4 elaborates the reaction of single porous particles. Solid-solid reactions proceeding through gaseous intermediates are considered in Chapter 5. Chapter 6 deals with the experimental approaches to the study of gas-solid reaction systems. How information on single-particle behavior may be used for the design of multiparticle, large-scale assemblies, and packed- and fluidized-bed reaction systems is deliberated in Chapter 7. The last chapter covers the specific gas-solid reaction systems, including some statistical indices indicating the economic importance of the systems and processes it's based on. This publication is recommended for practicing engineers engaged in process research, development, and design in the many fields where gas-solid reactions are important.

The Reduction of Iron Ores

The Reduction of Iron Ores PDF Author: Ludwig von Bogdandy
Publisher: Springer Science & Business Media
ISBN: 3662104008
Category : Science
Languages : en
Pages : 592

Book Description
For the English edition the book was revised by the authors, taking into account a number of suggestions of the readers of the German edition. Some of the most important publications in the field of iron ore reduction, which appeared since 1967, have been used to bring the manuscript as far as possible up to date. The kind assistance of Dr. K. BOHNENKAMP of the Max-Planck-Institut fUr Eisenforschung, Dusseldorf, was much appreciated in this respect. Ohapters 2.9 and 2.10, dealing with the reduction of molten oxide slags by solid carbon and with the contribution of the water-gas reaction to iron ore reduction, have been added for the English edition. Ohapter 2.9 has been completely revised with the kind assistance of Dr. H. J. GRABKE, Stuttgart. Dipl.-Ing. J. LODDE contributed to this edition by revising the bibliography. Owing to the rapid development of the blast furnace it was necessary to revise Ohapter 5 considerably. In this field many valuable suggestions have been made by Dipl.-Ing. G. LANGE and Dipl.-Ing. P. HEINRICH. Furthermore, Ohapters3 and 4 have been thoroughly revised by Dr.-Ing. E. FORSTER and Dr.-Ing. U. SCHIERLOH. Last, but not least, we have to thank our translators for their excellent work.

Extractive Metallurgy of Nickel, Cobalt and Platinum Group Metals

Extractive Metallurgy of Nickel, Cobalt and Platinum Group Metals PDF Author: Frank Crundwell
Publisher: Elsevier
ISBN: 0080968104
Category : Technology & Engineering
Languages : en
Pages : 623

Book Description
This book describes and explains the methods by which three related ores and recyclables are made into high purity metals and chemicals, for materials processing. It focuses on present day processes and future developments rather than historical processes. Nickel, cobalt and platinum group metals are key elements for materials processing. They occur together in one book because they (i) map together on the periodic table (ii) occur together in many ores and (iii) are natural partners for further materials processing and materials manufacturing. They all are, for example, important catalysts – with platinum group metals being especially important for reducing car and truck emissions. Stainless steels and CoNiFe airplane engine super alloys are examples of practical usage. The product emphasises a sequential, building-block approach to the subject gained through the author's previous writings (particularly Extractive Metallurgy of Copper in four editions) and extensive experience. Due to the multiple metals involved and because each metal originates in several types of ore – e.g. tropical ores and arctic ores this necessitates a multi-contributor work drawing from multiple networks and both engineering and science. - Synthesizes detailed review of the fundamental chemistry and physics of extractive metallurgy with practical lessons from industrial consultancies at the leading international plants - Discusses Nickel, Cobalt and Platinum Group Metals for the first time in one book - Reviews extraction of multiple metals from the same tropical or arctic ore - Industrial, international and multidisciplinary focus on current standards of production supports best practice use of industrial resources

Clean Ironmaking and Steelmaking Processes

Clean Ironmaking and Steelmaking Processes PDF Author: Pasquale Cavaliere
Publisher: Springer
ISBN: 3030212092
Category : Technology & Engineering
Languages : en
Pages : 624

Book Description
​This book describes the available technologies that can be employed to reduce energy consumption and greenhouse emissions in the steel- and ironmaking industries. Ironmaking and steelmaking are some of the largest emitters of carbon dioxide (over 2Gt per year) and have some of the highest energy demand (25 EJ per year) among all industries; to help mitigate this problem, the book examines how changes can be made in energy efficiency, including energy consumption optimization, online monitoring, and energy audits. Due to negligible regulations and unparalleled growth in these industries during the past 15-20 years, knowledge of best practices and innovative technologies for greenhouse gas remediation is paramount, and something this book addresses. Presents the most recent technological solutions in productivity analyses and dangerous emissions control and reduction in steelmaking plants; Examines the energy saving and emissions abatement efficiency for potential solutions to emission control and reduction in steelmaking plants; Discusses the application of the results of research conducted over the last ten years at universities, research centers, and industrial institutions.

Book Description
Steel is a critical material in our societies and will remain an important one for a long time into the future. In the last two decades, the world steel industry has gone through drastic changes and this is predicted to continue in the future. The Asian countries (e.g. China, India) have been dominant in the production of steel creating global over-capacity, while the steel industry in the developed countries have made tremendous efforts to reinforce its global leadership in process technology and product development, and remain sustainable and competitive. The global steel industry is also facing various grand challenges in strict environmental regulation, new energy and materials sources, and ever-increasing customer requirements for high quality steel products, which has been addressed accordingly by the global iron and steel community. This Special Issue, “Ironmaking and Steelmaking”, released by the journal Metals, published 33 high quality articles from the international iron and steel community, covering the state-of-the-art of the ironmaking and steelmaking processes. This includes fundamental understanding, experimental investigation, pilot plant trials, industrial applications and big data utilization in the improvement and optimization of existing processes, and research and development in transformative technologies. It is hoped that the creation of this special issue as a scientific platform will help drive the iron and steel community to build a sustainable steel industry.
