This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'augmentation croissante de la demande énergétique mondiale entraine une production importante de dioxyde de carbone fossile. Pour limiter ces émissions, les énergies alternatives renouvelables sont prometteuses, et notamment, l'utilisation de la biomasse. C'est dans ce contexte qu'a été mis en place le projet ANR GAMECO par un consortium rassemblant des laboratoires universitaires et des unités de R&D industrielles. Ce projet vise à consolider l'utilisation d'un lit fluidisé bouillonnant de gazéification sous air pour convertir de la biomasse lignocellulosique en gaz de synthèse. Ce travail de doctorat a pour ambition de répondre à l'une des problématiques de ce projet : la répartition des particules de biomasses et de semi-coke ou charbon au sein du lit fluidisé et sa prise en compte dans la modélisation du gazéifieur. L'étude a porté sur des mélanges contenant de l'olivine et des particules de bois de caractéristiques différentes. Les résultats de mélange-ségrégation présentés ont été obtenus grâce à des mesures en maquette froide développée dans le cadre de cette thèse. Les données expérimentales obtenues ont permis de valider et consolider un modèle de mélange-ségrégation de la littérature. La dernière étape de la thèse consiste en la mise en place d'un modèle global du réacteur à lit fluidisé de gazéification de la biomasse pour prédire la productivité et la qualité du gaz produit. Ce modèle intègre les résultats hydrodynamiques précédents auxquels sont couplés des réactions chimiques de conversion de la biomasse (pyrolyse, oxy-gazéification du charbon, craquage des goudrons) provenant de la littérature. Les résultats de ce modèle sont comparés aux résultats obtenus sur une maquette chaude.

Download or read book Lake Pavin written by Télesphore Sime-Ngando and published by Springer. This book was released on 2016-10-31 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book represents the first multidisciplinary scientific work on a deep volcanic maar lake in comparison with other similar temperate lakes. The syntheses of the main characteristics of Lake Pavin are, for the first time, set in a firmer footing comparative approach, encompassing regional, national, European and international aquatic science contexts. It is a unique lake because of its permanently anoxic monimolimnion, and furthermore, because of its small surface area, its substantially low human influence, and by the fact that it does not have a river inflow. The book reflects the scientific research done on the general limnology, history, origin, volcanology and geological environment as well as on the geochemistry and biogeochemical cycles. Other chapters focus on the biology and microbial ecology whereas the sedimentology and paleolimnology are also given attention. This volume will be of special interest to researchers and advanced students, primarily in the fields of limnology, biogeochemistry, and aquatic ecology.

Download or read book Integrated Forest Biorefineries written by Lew Christopher and published by Royal Society of Chemistry. This book was released on 2012-09-30 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: This reference book describes how bioprocessing and biotechnology could enhance the value extracted from wood-based lignocellulosic fiber by employing both biochemical and thermochemical conversion processes. It documents recent accomplishments and suggests future prospects for research and development of integrated forest biorefineries (IFBR) as the path forward for the pulp, paper and other fiber-processing industries. This is the only book to cover this area of high economic, social, and environmental importance. It is aimed at industrialists and academics from diverse science and engineering backgrounds including chemical and biotechnology companies, governmental and professional bodies, and scholarly societies. The Editor and contributors are internationally recognized scientists and many are leaders in their respective fields. The book starts with an introductory overview of the current state of biorefining and a justification for future developments. The next four chapters deal with social, economic and environmental issues related to regulations, biomass production and supply, process modelling, and life cycle analysis. Subsequent chapters focus on the extraction of biochemicals from biomass and their potential utilization to add value to the IFBR prior to pulping. The book then presents, compares and evaluates two types of forest biorefineries based on kraft and organosolv pulping. Finally, the book assess the potential of waste biomass and streams, such paper mill sludge and black liquor, to serve as feedstock for biofuel production and value-added biomaterials through both the biochemical and thermochemical routes of biomass bioprocessing. The economics of the described IFBR processes and products, and their environmental impact, is a major focus in most of the chapters. Practical examples are presented where relevant and applicable.
Download or read book Woody Plants in Agro Ecosystems of Semi Arid Regions written by Henk Breman and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a quantitative analysis of the role of woody plants in semi-arid regions, for the aSSessment of their benefits in agrosylvopastoralland-use systems with productive and sus tainability objectives. The insights presented and conclusions drawn allow the additional benefits of woody plants for specific climatic and physical site conditions and land-use systems to be estimated. The Sahel and Sudan zones in West Africa, on which the book focusses, represent resource-poor conditions, whose ecological dynamics have been relatively well studied. The role of woody plants in this region, as assessed in this book, is extrapolated to other semi-arid regions, leading to general conclusions on agroforestry's potential as an option for sustainable land use in semi-arid regions. The origins of this book go back to 1982, when the Club du Sahel requested that available data on woody plants in the Sahel region be synthesised, to provide basic information to enable better attention to be given to woody plants in rural development programmes. We are grateful to the Club du Sahel for this challenge. Various people contributed to studies used in this book. The preliminary inventory of the data available was made by Frits Ohler; later his work was continued by Franciska Dekker.

Available in PDF, EPUB and Kindle. Book excerpt: Ô. . . this book is a very useful resource for the lawyer. . . makes a good start by presenting a wide-ranging portfolio of multidisciplinary research that will assist in progressing the task, challenging though it may be.Õ Ð Chris Rodgers, Environmental Liability This book explores the interaction between climate change and the agriculture sector. Agriculture is essential to the livelihood of people and nations, especially in the developing world; therefore, any impact on it will have significant economic, social, and political ramifications. Scholars from around the world and from various fields have been brought together to explore this important topic. The contributions found here analyze direct agronomic effects, the economic impacts on agriculture, agricultural impacts on the economy, agricultural mitigation, and farmer adaptation. The authors argue that climate change is likely to have an extensive impact on agriculture around the world through changes in temperature, precipitation, concentrations of carbon dioxide, and available water flows. This thorough and timely volume is an invaluable resource for anyone interested in exploring the impacts of climate change in arguably the most important sector of the world economy. Economists, agronomists, and climate modelers in academia and the public sector, policy analysts and development agency staff, and graduate/postgraduate students will find this remarkable volume a welcome addition to their collection.

Download or read book Traditional Forest Related Knowledge written by John A. Parrotta and published by Springer Science & Business Media. This book was released on 2011-10-14 with total page 639 pages. Available in PDF, EPUB and Kindle. Book excerpt: Exploring a topic of vital and ongoing importance, Traditional Forest Knowledge examines the history, current status and trends in the development and application of traditional forest knowledge by local and indigenous communities worldwide. It considers the interplay between traditional beliefs and practices and formal forest science and interrogates the often uneasy relationship between these different knowledge systems. The contents also highlight efforts to conserve and promote traditional forest management practices that balance the environmental, economic and social objectives of forest management. It places these efforts in the context of recent trends towards the devolution of forest management authority in many parts of the world. The book includes regional chapters covering North America, South America, Africa, Europe, Asia and the Australia-Pacific region. As well as relating the general factors mentioned above to these specific areas, these chapters cover issues of special regional significance, such as the importance of traditional knowledge and practices for food security, economic development and cultural identity. Other chapters examine topics ranging from key policy issues to the significant programs of regional and international organisations, and from research ethics and best practices for scientific study of traditional knowledge to the adaptation of traditional forest knowledge to climate change and globalisation.
