This book presents a concise framework for assessing technical and sustainability impacts of existing biorefineries and provides a possible road map for development of novel biorefineries. It offers a detailed, integrated approach to evaluate the entire biomass production chain, from the agricultural feedstock production and transportation, to the industrial conversion and commercialization & use of products. The Brazilian sugarcane biorefinery is used as a case study; however, the methods and concepts can be applied to almost any biomass alternative. Chapters explore the main issues regarding biorefinery assessment, including feedstock production and transportation modeling, biofuels and green chemistry products, as well as assessment of sustainability impacts. This book is a valuable source of information to researchers in bioenergy, green chemistry and sustainability fields. It also provides a useful framework for government agencies, investors and the energy industry to evaluate and predict the success of current and future biorefinery alternatives.

This book reports the results of exhaustive research work on modeling and control of vertical oil well drilling systems. It is focused on the analysis of the system-dynamic response and the elimination of the most damaging drill string vibration modes affecting overall perforation performance: stick-slip (torsional vibration) and bit-bounce (axial vibration). The text is organized in three parts. The first part, Modeling, presents lumped- and distributed-parameter models that allow the dynamic behavior of the drill string to be characterized; a comprehensive mathematical model taking into account mechanical and electric components of the overall drilling system is also provided. The distributed nature of the system is accommodated by considering a system of wave equations subject to nonlinear boundary conditions; this model is transformed into a pair of neutral-type time-delay equations which can overcome the complexity involved in the analysis and simulation of the partial differential equation model. The second part, Analysis, is devoted to the study of the response of the system described by the time-delay model; important properties useful for analyzing system stability are investigated and frequency- and time-domain techniques are reviewed. Part III, Control, concerns the design of stabilizing control laws aimed at eliminating undesirable drilling vibrations; diverse control techniques based on infinite--dimensional system representations are designed and evaluated. The control proposals are shown to be effective in suppressing stick-slip and bit-bounce so that a considerable improvement of the overall drilling performance can be achieved. This self-contained book provides operational guidelines to avoid drilling vibrations. Furthermore, since the modeling and control techniques presented here can be generalized to treat diverse engineering problems, it constitutes a useful resource to researchers working on control and its engineering application in oil well drilling.

This book solves the open problems in fluid flow modeling through the fractured vuggy carbonate reservoirs. Fractured vuggy carbonate reservoirs usually have complex pore structures, which contain not only matrix and fractures but also the vugs and cavities. Since the vugs and cavities are irregular in shape and vary in diameter from millimeters to meters, modeling fluid flow through fractured vuggy porous media is still a challenge. The existing modeling theory and methods are not suitable for such reservoir. It starts from the concept of discrete fracture and fracture-vug networks model, and then develops the corresponding mathematical models and numerical methods, including discrete fracture model, discrete fracture-vug model, hybrid model and multiscale models. Based on these discrete porous media models, some equivalent medium models and methods are also discussed. All the modeling and methods shared in this book offer the key recent solutions into this area.

Liberating Energy from Carbon analyzes energy options in a carbon-constrained world. Major strategies and pathways to decarbonizing the carbon-intensive economy are laid out with a special emphasis on the prospects of achieving low-risk atmospheric CO2 levels. The opportunities and challenges in developing and bringing to market novel low and zero-carbon technologies are highlighted from technical, economic and environmental viewpoints. This book takes a unique approach by treating carbon in a holistic manner-tracking its complete transformation chain from fossil fuel sources to the unique properties of the CO2 molecule, to carbon capture and storage and finally, to CO2 industrial utilization and its conversion to value-added products and fuels. This concise but comprehensive sourcebook guides readers through recent scientific and technological developments as well as commercial projects that aim for the decarbonization of the fossil fuel-based economy and CO2 utilization that will play an increasingly important role in the near- and mid-term future. This book is intended for researchers, engineers, and students working and studying in practically all areas of energy technology and alternative energy sources and fuels.

Carbon Capture and Storage technologies (CCS) are moving from experiment toward commercial applications at a rapid pace, driven by urgent demand for carbon mitigation strategies. This book examines the potential role of CCS from four perspectives: technology development, economic competitiveness, environmental and safety impacts, and social acceptance. IEK-STE of Forschungszentrum Juelich presents this interdisciplinary study on CCS, based on methods of Integrated Technology Assessment. Following an introductory chapter by editor Wilhelm Kuckshinrichs, Part I of the book surveys the status of carbon capture technologies, and assesses the potential for research and development of applications that are useful at scales required for meaningful mitigation. Transportation, Utilization and Environmental Aspects of CO2 receive chapter-length treatments, and the section concludes with an examination of safe geological storage of CO2 based on the example of the Ketzin pilot site, not far from Berlin. Part II covers Economic and Societal Perspectives. The first chapter discusses the use of CCS in the energy sector, analyzing costs associated with electricity generation and CO2 mitigation on the basis of technology-specific cost and process parameters, along with a merit-order illustration of the possible implications of CCS facilities for energy costs. Later chapters outline the costs of CCS application in energy- and CO2-intensive industries; analyze system characteristics of CCS infrastructures, showing that the infrastructure cost function depends on the ratio of fixed to variable costs, as well as on the spatial distribution of CO2 sources and storage facilities; interpret cross-sector carbon mitigation strategies and their impacts on the energy and CO2 balance; and discuss awareness and knowledge of CCS, attitudes towards it, and how the risks and benefits of CCS are perceived. Part III discusses the Framework for Energy and Climate Policy, with chapters on acceptance and adoption of CCS policy in Germany, and the EU, and an assessment of international cooperation in support of CCS. The final chapter summarizes the central arguments, discusses the potential role of carbon capture and utilization as part of a German transformation strategy, and extrapolates the findings to European and international contexts.

industry, and 22% were from government. A total of oral presentations (including Special Topic presentations) and 329 poster presentations were delivered. The high number of poster submissions required splitting the poster session into two evening sessions. (Conference details are posted at http: //www.eere.energy.gov/biomass/biotech_symposium/.) Almost 35% of the attendees were international, showing the strong and building worldwide interest in this area. Nations represented included Australia, Austria, Belgium, Brazil, Canada, Central African Republic, China, Denmark, Finland, France, Gambia, Germany, Hungary, India, Indonesia, Italy, Japan, Mexico, The Netherlands, New Zealand, Portugal, South Africa, South Korea, Spain, Sweden, Thailand, Turkey, United Ki- dom, and Venezuela, as well as the United States. One of the focus areas for bioconversion of renewable resources into fuels is conversion of lignocellulose into sugars and the conversion of s- ars into fuels and other products. This focus is continuing to expand toward the more encompassing concept of the integrated multiproduct biorefinery--where the production of multiple fuel, chemical, and energy products occurs at one site using a combination of biochemical and ther- chemical conversion technologies. The biorefinery concept continues to grow as a unifying framework and vision, and the biorefinery theme f- tured prominently in many talks and presentations. However, another emerging theme was the importance of examining and optimizing the entire biorefining process rather than just its bioconversion-related elements

The first edition of the book Coal: Typology - Chemistry - Physics - Constitution appeared in 1961. In 1981 a new edition was published in which the text was unaltered proving that after 20 years the book was still considered a standard work in its field. The enormous activities in the 80's in the field of coal conversion processes (especially gasification and
liquefaction) and the equally amazing development of instrumental techniques of observation and analysis prompted a complete revision and update of the book. The present edition contains 1000 pages compared to the 514 pages of its predecessors of 1961 and 1981. The number of illustrations has greatly increased from 253 to 574 and that of the tables from 76 to 208. These figures amply testify to the increase in coal research.

Compared with its former editions, the present book treats a considerable number of new subjects: modern concepts of geotectonics and of organic geochemistry; the problem of pseudohomogeneity of vitrinite; developments of the classification and systematics of coals and coal components (macerals); an expose on electron microscopy and the most important instrumental physical methods of analysis (FTIR, NMR, ESCA and analytical pyrolysis combined with gas chromatography and mass spectroscopy); the principles of physical-statistical structure analysis based on the concept of additivity of a large number of molar functions; a revision of Seyler's ideas of discrete steps in coalification; an essay on coal fluorescence; and the survey on magnetic properties - magnetic susceptibility and magnetic resonance - is considerably enlarged. A completely new chapter is added on cohesion and adhesion phenomena as found in coals. The chapter on solvent extraction and solubilisation is
significantly enlarged and new concepts are discussed. The actions of hydrogen, molecular oxygen and oxidising agents on coal are updated and a newly written chapter treats the grand processes of coal conversion (combustion, gasification, carbonisation and liquefaction). Coal constitution in its diverse aspects is revised with a practically complete survey of many proposed coal models. Essays on synthetic coal analogues and on the simulation of natural coalification are added. Also new is the compendium, a set of comprehensive tables, containing the most important numerical data of this book in a fully
comparative form.

Every chapter has its own bibliography, divided into general references (leading books on the treated subject) and special references, which are quotations of scientific papers discussed in the text. The extensive subject index, complete index of names and the compendium are provided in order to facilitate usage as an encyclopedic work.

This book provides insights into the development and usage of coal in chemical engineering. The reactivity of coal in processes such as pyrolysis, gasification, liquefaction, combustion and swelling is related to its structural properties. Using experimental findings and theoretical analysis, the book comprehensively answers three crucial issues that are fundamental to the optimization of coal chemical conversions: What is the structure of coal? How does the underlying structure determine the reactivity of different types of coal? How does the structure of coal alter during coal conversion? This book will be of interest to both individual readers and institutions involved in teaching and research into chemical engineering and energy conversion technologies. It is aimed at advanced- level undergraduate students. The text is suitable for readers with a basic knowledge of chemistry, such as first-year undergraduate general science students. Higher-level students with an in-depth understanding of the chemistry of coal will also benefit from the book. It will provide a useful reference resource for students and university-level teachers, as well as practicing engineers.

Convective heat tranfer is the result of fluid flowing between objects of different temperatures. Thus it may be the objective of a process (as in refrigeration) or it may be an incidental aspect of other processes. This monograph reviews in a concise and unified manner recent contributions to the principles of convective heat transfer for single- and multi-phase systems: It summarizes the role of the fundamental mechanism, discusses the governing differential equations, describes approximation schemes and phenomenological models, and examines their solutions and applications. After a review of the basic physics and thermodynamics, the book divides the subject into three parts. Part 1 deals with single-medium transfer, specifically with intraphase transfers in single-phase flows and with intramedium transfers in two-phase flows. Part 2 deals with fluid-solid transfer processes, both in cases where the interface is small and in cases where it is large, as well as liquid-liquid transfer processes. Part 3 considers three media, addressing both liquid-solid-solid and gas-liquid-solid systems.

Chemical structure and bonding. The scope of the series spans the entire Periodic Table and addresses structure and bonding issues associated with all of the elements. It also focuses attention on new and developing areas of modern structural and theoretical chemistry such as nanostructures, molecular electronics, designed molecular solids, surfaces, metal clusters and supramolecular structures. Physical and spectroscopic techniques used to determine, examine and model structures fall within the purview of Structure and Bonding to the extent that the focus is on the scientific results obtained and not on specialist information concerning the techniques themselves. Issues associated with the development of bonding models and generalizations that illuminate the reactivity pathways and rates of chemical processes are also relevant. The individual volumes in the series are thematic. The goal of each volume is to give the reader, whether at a university or in industry, a comprehensive overview of an area where new insights are emerging that are of interest to a larger scientific audience.

This textbook deals with the physics and chemistry of energy resources, bringing together material having to do with a wide range of resources - coal gas, oil, hydropower, and nuclear. After a brief introduction to the concepts of force, work, and energy the book discusses energy resources: specifically, the worldwide reserves of fossil fuels, the uses to which these fuels are put, and the conversion of fuels into other forms - such as the conversion of coal to gas or liquid fuels. This is followed by discussions of electric power and of nuclear, solar, geothermal and other methods for generating electricity. The discussion then turns to the uses of energy in agriculture, transportation and so forth, and the pollution that accompanies these uses. The book concludes with discussions of energy conservation and projections of energy supplies for the future. Intended for a general-education course in natural sciences, it will also be useful for teachers of science in high schools. The presentation assumes no prior knowledge of physics or chemistry, but it includes the necessary background information where needed.

The overall goal in this book is to explain key economic, environmental, technology, and transportation factors that are affecting the provincial and industrial energy intensities and environmental pollution in the People's Republic of China (China). The author defines energy intensity as the energy consumption per unit of output. She concentrates on China, because it is the second largest energy user and pollution generator in the world. In this book, the focus is on the cokemaking sector in the Shanxi Province. Cokemaking is the largest consumer of coal in the region, using more than one-half of the coal consumed there. Throughout the book, the author stresses the important role of the Shanxi Province in encouraging improvements in energy efficiency and pollution by (1) introducing new coke-oven technologies and (2) encouraging pollution-abatement measures for the older ovens.
