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.

Book Description :

High temperature gas-solid reactions are ubiquitous on planetary bodies, distributing chemical elements over a range of geologic settings and temperatures. This volume reviews the critical role gas-solid reactions play in early solar system formation, volcanism, metamorphism and industrial processes. The field evidence, experimental and theoretical approaches for examining gas-solid reaction are presented, building on advances in fields outside of Earth Sciences. Computational chemistry techniques are used to probe the nature of molecular clusters and solvation in volcanic vapors and mineral-gas reaction mechanisms. Specialised analytical methods for characterising solid reaction products are included since these reactions commonly form thin or dispersed films and metastable minerals. Finally, the volume contains rich field examples, laboratory experiments and thermodynamic modelling and kinetics of gas-solid reactions on Earth, Venus and beyond.

Book Description :

Pharmaceutical and fine chemical products are typically synthesised batchwise which is an anomaly since batch processes have a series of practical and economical disadvantages. On the contrary, flow continuous processes present a series of advantages leading to new ways to synthesise chemical products. Flow processes - * enable control reaction parameters more precisely (temperature, residence time, amount of reagents and solvent etc.), leading to better reproducibility, safer and more reliable processes * can be performed more advantageously using immobilized reagents or catalysts * improve the selectivity and productivity of the process and possibly even the stability of the catalyst * offer opportunities for heat exchange and energy conservation as well as an easy separation and recycling of the reactants and products by adequate process design * achieve multistep syntheses by assembling a line of reactors with minimum or no purification in between two reaction steps * can be assured by facile automation * scale-up can be easily conducted by number-up With all the new research activity in manufacturing chemical products, this comprehensive book is very timely, as it summarises the latest trends in organic synthesis. It gives an insight into flow continuous processes, outlining the basic concepts and explaining the terminology of, and systems approach to, process design dealing with both homogeneous and heterogeneous catalysis and mini- or micro-reactors. The book contains case studies, extensive bibliographies and reference lists in each chapter to enable the reader to grasp the contents and to go on to more detailed texts on specific subjects if desired. The book is written by both organic chemists and engineers giving a multidisciplinary vision of the new tools and methodologies in this field. It is essential reading for organic chemists (in industry or academia) working alongside chemical engineers or who want to undertake chemical engineering projects. It will also be of interest for chemical engineers to see how basic engineering concepts are applied in modern organic chemistry.

Book Description :

This book addresses the two major issues faced by the modern steel industry: CO2 emissions and energy consumption. The steel industry accounts for 6.7% of the anthropogenic CO2 emissions and consumes 6% of the total energy consumed in manufacturing. In response to these critical issues, a new technology called flash ironmaking has been developed, aimed at producing iron directly from iron ore concentrate using gaseous reductants/fuels such as natural gas or hydrogen. This ironmaking technology takes advantage of the rapid reaction rate of fine particles and bypasses the palletization process. This book discusses the principles of flash ironmaking, laboratory experiments, and design and operation of a prototype flash reactor. • Provides theories and principles of ironmaking and a novel ironmaking technology. • Includes laboratory experiments to establish the kinetic feasibility of flash ironmaking. • Covers the design and operation of a prototype flash reactor as well as the design of industrial-size flash ironmaking reactors. • Describes various cases of flow sheet development, which forms the basis for process analysis and simulation • Presents economic analysis case studies. Presenting a novel technology that addresses contemporary issues facing one of the largest manufacturing industries, this book is aimed at professionals and researchers in metallurgy, materials engineering, manufacturing engineering, and related disciplines.

Book Description :

The metallurgical processing of ferroalloys is based on a coherent combination of many scientific fields, which are briefly outlined in this chapter. The metal’s recovery process is based on reduction reactions, where metallurgical thermodynamics and kinetics are of a paramount importance. This includes the knowledge and ability to calculate, monitor, and change the formation of solutions and phases, rate of the reactions, and handling of reaction products in the most efficient way. In parallel, theoretical and engineering data on heat, mass, momentum, and charge transfer are critical for the development and design of ferroalloy production processes and furnaces. The chapter also discusses the basics of the structure and properties of metal and oxide (slag) when melted together with carbon reductants.

Book Description :

The widespread adoption of microreactors has been hindered by a lack of knowledge regarding rules and parameters needed for their design. This dissertation deals with the investigation of interfacial area and liquid mass transport in microreactors for gas/liquid reactions. Observations of a reduction in conversion occurring when changing from a glass laboratory device to a stainless steel process device motivated investigations into the effect of material and surface properties on the gas/liquid flow and reaction. This work takes a look inside the machined microstructures produced at the Institute for Micro Process Engineering of the Karlsruhe Institute of Technology and investigates the nature of the solid surfaces resulting from the machining process—the surface roughness and the contact angle of the resulting surface. The effect of wettability on gas/liquid flow in microreactors has been investigated in capillaries of various materials. The absorption of carbon dioxide into aqueous solutions of sodium hydroxide has been used to investigate gas/liquid flow and reaction in capillaries and in a microstructured falling film reactor. Under certain limiting assumptions depending upon the exact rates of reaction and transport, values of the interfacial area and liquid mass transport coefficient can be derived from measurements of reaction. This dissertation contributes a small step towards a better understanding of how measurements of the interfacial area and mass transfer coefficient can be performed, demonstrates why the effect of material wettability cannot be ignored, and provides a stronger basis for further work in the development of general correlations describing microstructured gas/liquid reactors.
