This book was released on 2010 with total page 259 pages. Available in PDF, EPUB and Kindle. Book excerpt: Des applications avancées, telles que la production catalytique de combustibles liquides, demande un gaz de synthèse de haute pureté. La biomasse semble être une matière première prometteuse, mais le gaz doit être nettoyé de façon drastique pour atteindre les spécifications. Le reformage à haute température (> 1300 K) est une alternative crédible à la voie catalytique. La cinétique de reformage à haute température dans une atmosphère réductrice est mal connue. Si des mécanismes détaillés existent déjà pour la combustion d'hydrocarbures, les réactions sensibles sont différentes dans ce cas. Une étude expérimentale en réacteur piston et une modélisation du vapocraquage d'hydrocarbures ont été réalisées. L'influence cinétique des gaz présents dans le gaz de synthèse sur la conversion des hydrocarbures a été étudiée. Le comportement de mélanges complexes représentatifs des gaz à traiter a été étudié en fonction de la température. L'espèce la plus difficile à reformer est le méthane : une température supérieure à 1700 K est nécessaire. Un modèle dérivé de celui de la combustion des hydrocarbures légers a été élaboré. Les tendances expérimentales sont bien reproduites. Le reformage du carbone se fait principalement par réaction des radicaux OH avec les C2 insaturés, précurseurs de suie. Les conditions nécessaires pour reformer le méthane à haute température sont également donc favorables à la formation de suies indésirables.

Book excerpt: As a follow-up to the Handbook of Gasification Technology, also from Wiley-Scrivener, Synthesis Gas goes into more depth on how the products from this important technology can reduce our global carbon footprint and lead the United States, and other countries, toward energy independence. The environmental benefits are very high, and, along with carbon capture and renewable fuels, synthesis gas (or syngas) is a huge step toward environmental sustainability. Synthesis gas is one of the most important advancements that has ever occurred in energy production. Using this technology, for example, coal, biomass, waste products, or a combination of two or more of these can be gasified into a product that has roughly half the carbon footprint of coal alone. Used on a massive scale, just think of the potential for reducing carbon emissions! Synthesis Gas covers all aspects of the technology, from the chemistry, processes, and production, to the products, feedstocks, and even safety in the plant. Whether a veteran engineer or scientist using it as a reference or a professor using it as a textbook, this outstanding new volume is a must-have for any library.

This book was released on 2008 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cette thèse vise à comprendre et modéliser les mécanismes mis en jeu dans un réacteur de traitement de gaz de pyrolyse (RTGP) de biomasses sur un lit fixe constitué du résidu carboné. L'objectif est de produire un gaz de synthèse (CO + H2) ayant une teneur en goudrons inférieure à 0,1 mg/Nm3. Au niveau conceptuel le système matériel a été caractérisé et un schéma réactionnel simplifié a été identifié à l'aide de composés modèles sélectionnés pour être représentatifs des goudrons en terme de réactivité, révélateurs des mécanismes réactionnels et traceurs en entrée et sortie du RTGP. Un dispositif expérimental à échelle réduite, mini-RTGP, a été développé et les méthodes et protocoles d'analyse mis au point. Des expériences ont été menées afin de comprendre les mécanismes de dégradation du méthane et des composés modèles et de gazéification du résidu carboné ainsi que d'apporter des informations préliminaires sur les cinétiques. Un modèle du RTGP a également été développé.

This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: La conversion thermochimique à haute température (>700°C) de la biomasse en double lit fluidisé circulant est une voie alternative aux énergies fossiles (pétrole, charbon) pour la production d'un gaz de synthèse à haute valeur énergétique, utilisable dans de nombreuses applications. L'objectif de cette thèse est de développer des méthodologies et des outils théoriques et expérimentaux permettant d'accéder aux cinétiques des transformations élémentaires (pyrolyse de la biomasse, gazéification et combustion du char, craquage et reformage des goudrons) présentes dans le procédé de gazéification de la biomasse en double lit fluidisé circulant. Dans un premier temps, un mini-réacteur à lit fluidisé fonctionnant entre 300 et 1000°C avec une alimentation en gaz parfaitement contrôlée (N2, O2, H2, H2O et goudrons) a été conçu et mis au point au Laboratoire de Génie Chimique de Toulouse. Un système d'échantillonnage et d'analyse de la phase gaz permet de quantifier en continu les fractions molaires des gaz incondensables et des goudrons produits. Une étude hydrodynamique et thermique a permis de déterminer les points de fonctionnement du réacteur pour chaque transformation élémentaire étudiée. Dans un second temps, les études de gazéification et de combustion du char ont été réalisées dans le mini-réacteur à lit fluidisé. L'influence de nombreux paramètres opératoires (température, pression partielle des différents constituants) a permis de comprendre la formation des différents produits et de modéliser les cinétiques de transformation du solide. Dans le cas de la combustion du char, un mécanisme réactionnel a également été établi et la cinétique obtenue en lit fluidisé a été comparée à celle déterminée par analyse thermogravimétrique. Enfin, une étude sur le reformage d'un goudron modèle (toluène) en lit fluidisé a mis en évidence l'effet de l'atmosphère réactionnelle sur le mécanisme de dégradation du toluène sur l'olivine et le char.

Available in PDF, EPUB and Kindle. Book excerpt: Advances in Hydrogen Production, Storage and Distribution reviews recent developments in this key component of the emerging "hydrogen economy," an energy infrastructure based on hydrogen. Since hydrogen can be produced without using fossil fuels, a move to such an economy has the potential to reduce greenhouse gas emissions and improve energy security. However, such a move also requires the advanced production, storage and usage techniques discussed in this book. Part one introduces the fundamentals of hydrogen production, storage, and distribution, including an overview of the development of the necessary infrastructure, an analysis of the potential environmental benefits, and a review of some important hydrogen production technologies in conventional, bio-based, and nuclear power plants. Part two focuses on hydrogen production from renewable resources, and includes chapters outlining the production of hydrogen through water electrolysis, photocatalysis, and bioengineered algae. Finally, part three covers hydrogen production using inorganic membrane reactors, the storage of hydrogen, fuel cell technology, and the potential of hydrogen as a fuel for transportation. Advances in Hydrogen Production, Storage and Distribution provides a detailed overview of the components and challenges of a hydrogen economy. This book is an invaluable resource for research and development professionals in the energy industry, as well as academics with an interest in this important subject. - Reviews developments and research in this dynamic area - Discusses the challenges of creating an infrastructure to store and distribute hydrogen - Reviews the production of hydrogen using electrolysis and photo-catalytic methods
