Book excerpt: L'objectif de ce travail était d'une part d'étudier la dégradation du phénol en milieu aqueux par un plasma GlidArc d'air humide et d'autre part d'étudier la conversion de l'acétaldéhyde dans des gaz atmosphériques par un plasma DBD généré par une haute tension impulsionnelle. Les résultats de l'étude paramétrique de la dégradation du phénol ont montré une augmentation de l'efficacité en fonction de la concentration initiale et du débit d'air humide. L'augmentation du gap entre les électrodes à occasionné celle de la concentration des ions nitrates. La majeur parie des nombreux produits de réactions est constituée d'acides carboxyliques mais aussi d'hydroquinone, de para-nitrophénol et de para-nitrosophénol. Cette identification a permis de dresser un schéma réactionnel de la dégradation du phénol. La conversion de l'acétaldéhyde a été effectuée dans des conditions de température allant de l'ambiante jusqu'à 300°C et dans deux types de mélanges: CH3CHO/N2 et CH3CHO/N2/O2 (jusqu'à 10% O2). Les résultats ont montré que le coût énergétique baisse en présence d'oxygène dans le mélange et également lorsque la température augmente. Les principaux sous-produits identifiés dans CH3CHO/N2 sont CO, H2, CH4, HCN, C2H6, CH3CN tandis que dans les mélanges oxygénés, CO2 et CO, CH2O, CH3OH sont les sous-produits les plus importants. L'étude cinétique menée à la suite de cette analyse grâce à un modèle 0D simplifié a permis de mettre en évidence le rôle primordial de la dissociation par quenching des états métastables d'azote et de l'oxydation notamment par O et OH dans la conversion de l'acétaldéhyde. La modélisation a aussi permis de comprendre les processus de formation des sous-produits majoritaires. Des catalyseurs à base de MnO2 ont été placés en aval de la zone de décharge pour décomposer l'ozone qui se forme abondamment dans les mélanges oxygénés surtout à basse température. L'oxygène atomique produit lors de cette décomposition oxyde l'acétaldéhyde résiduel et ses sous-produits. Le coût énergétique a ainsi été diminué et les concentrations des sous-produits comme CH2O et CH3OH ont été réduites.
Book Synopsis Oxydation catalytique de composés organiques volatils (COV) par un procédé associant un plasma froid et un catalyseur by : Cécile Ayrault

This book was released on 2004 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ces travaux s'inscrivent dans le cadre de la dépollution atmosphérique et des nuisances olfactives. L'élimination des composés organiques volatils peut être réalisée selon plusieurs voies. L'oxydation catalytique étant une technique très efficace, l'élimination de la 2-heptanone a été étudiée en présence de catalyseur à base d'oxydes métalliques ou de métaux nobles supportés. Un catalyseur à base de platine permet l'élimination complète de la 2-heptanone vers 200ʿC. L'utilisation conjointe d'un plasma hors équilibre permet d'activer le système à température ambiante, réduisant ainsi la dépense énergétique. Plusieurs réacteurs associant un plasma froid et un catalyseur ont été développés et caractérisés (bilan énergétique et efficacité d'élimination). Toutefois, la génération d'ozone observée avec de tels systèmes nécessite l'emploi d'un catalyseur de destruction de O3 pour une éventuelle utilisation domestique.

Book Synopsis Frozen Food Science and Technology by : Judith A. Evans
Download or read book Frozen Food Science and Technology written by Judith A. Evans and published by John Wiley & Sons. This book was released on 2009-01-21 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive source of information on freezing and frozen storage of food. Initial chapters describe the freezing process and provide a fundamental understanding of the thermal and physical processes that occur during freezing. Experts in each stage of the frozen cold chain provide, within dedicated chapters, guidelines and advice on how to freeze food and maintain its quality during storage, transport, retail display and in the home. Individual chapters deal with specific aspects of freezing relevant to the main food commodities: meat, fish, fruit and vegetables. Legislation and new freezing processes are also covered. Frozen Food Science and Technology offers in-depth knowledge of current and emerging refrigeration technologies along the entire frozen food chain, enabling readers to optimise the quality of frozen food products. It is aimed at food scientists, technologists and engineers within the frozen food industry; frozen food retailers; and researchers and students of food science and technology.

Available in PDF, EPUB and Kindle. Book excerpt: I am pleased to present a work which marks a milestone in the history of public works and, more precisely, in that of permanent structures—a comprehensive dictionary of Civil Engineering terms. Since the beginning of time, Man has always tried to find a means to clear the obstacles which nature erected to displace him. With the first tree trunk thrown across a river, man sought to improve the crossing structure. After the invention of the wheel, and to satisfy his thirst for conquest (Roman ways), and comfort (aqueducts), man built bridges that became a preremptory necessity to move quickly. Thus, Man started to build wooden and masonry works. With the passing centuries, the builders became masters in the art of building masonry works. Then came the Industrial Revolution and the advent of the steel (1864), which was closely followed by the invention of the reinforced concrete (1855). The need for railways and improving the road network inspired great works of crossing such as viaducts and tunnels. The boom of the railway network and the development of the car required the construction of an increasing number of new structures. This phenomenon continues today with hundreds of structures built each year throughout the world.

Book Synopsis Oxidative Stress and Redox Regulation by : Ursula Jakob
Download or read book Oxidative Stress and Redox Regulation written by Ursula Jakob and published by Springer Science & Business Media. This book was released on 2013-03-15 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many physiological conditions such as host defense or aging and pathological conditions such as neurodegenerative diseases, and diabetes are associated with the accumulation of high levels of reactive oxygen species and reactive nitrogen species. This generates a condition called oxidative stress. Low levels of reactive oxygen species, however, which are continuously produced during aerobic metabolism, function as important signaling molecules, setting the metabolic pace of cells and regulating processes ranging from gene expression to apoptosis. For this book we would like to recruit the experts in the field of redox chemistry, bioinformatics and proteomics, redox signaling and oxidative stress biology to discuss how organisms achieve the appropriate redox balance, the mechanisms that lead to oxidative stress conditions and the physiological consequences that contribute to aging and disease.

Book Synopsis Food Chemistry Research Developments by : Konstantinos N. Papadopoulos
Download or read book Food Chemistry Research Developments written by Konstantinos N. Papadopoulos and published by Nova Publishers. This book was released on 2008 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food chemistry is the study of chemical processes and interactions of all biological and non-biological components of foods. The biological substances include such items as meat, poultry, lettuce, beer, and milk as examples. It is similar to biochemistry in its main components such as carbohydrates, lipids, and protein, but it also includes areas such as water, vitamins, minerals, enzymes, food additives, flavours, and colours. This discipline also encompasses how products change under certain food processing techniques and ways either to enhance or to prevent them from happening. An example of enhancing a process would be to encourage fermentation of dairy products with lactic acid; an example of a preventing process would be stopping the Maillard reaction on the surface of freshly cut Red Delicious apples whether by hand or mechanical methods. This book presents the recent research from around the world in this field.
