Download or read book The Reduction of Iron Ores written by Ludwig von Bogdandy and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 592 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Gas Solid Reactions written by Julian Szekely and published by Elsevier. This book was released on 2012-12-02 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: ​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 excerpt: In the present investigation, an attempt has been done to study the simultaneous effects of the major processing variables on the extent of reduction of iron ore pellets surrounded by coal or charcoal fines in an externally heated cylindrical steel container (diameter 5cm and height 10cm) placed in muffle furnace. The project goal is to compare the reduction potential of coal and charcoal in reduction of iron ore pellets. Wood charcoal contains very low levels of gangue, sulphur and volatile matter therefore, presenting itself as a very desirable reductant for the reduction of iron ore. The variables studied are time and temperature. The reduction was done at temperatures 8500C, 9000C, 9500C and 10000c. The percentage (degree) of reduction of pellets was calculated at 15, 30, 45, 60 and 90 minutes, after the furnace reached the predetermined reduction temperature. The experiments were statistically designed such that the effect of each variable can be quantitatively assessed and compared. The results showed that, there is an increase in degree of reduction with increase in time and temperature and use of charcoal instead of coal also increased the degree of reduction due to higher fixed carbon content of charcoal. The percentage of swelling showed a random variation with time and temperature. The activation energy for the reduction of iron ore pellet was found to be higher in case of coal as compared to that of in case of charcoal; this indicates that reduction of iron ore by charcoal will be more favorable in case of charcoal.

Available in PDF, EPUB and Kindle. Book excerpt: Reduction of Iron Ore Pellets with a particular percentage of binders i.e. 2% of Dextrine and 2% of Bentonite was carried out for the temperature range 900 to 1050°C. In reduction kinetic study the most satisfactory model was to taken, the slope of the initial linear region of fractional reduction vs. time curve was measured, which gives the rate constant (k). Ln k vs. 1/T plots were straight line from which Activation Energy was calculated. Pellets having different percentages of binders were reduced and compared to find the effect of binders.
