Download or read book Increased Biodiesel Efficiency written by Magno Trindade and published by Springer. This book was released on 2018-01-28 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book advances the use of biodiesel—more environmentally friendly than traditional fossil fuels—by showing how it can be synthesized at a lower cost, with greater efficiency and as a more pure and stable product. It presents methods based on fluorescence spectroscopy, which are less time-consuming than the traditional Rancimat analysis for monitoring stability, and are therefore less prone to allowing oxidative decay in the biofuel. Biodiesel exploits a variety of raw materials, from freshly harvested cottonseed to recycled cooking oil. These are cheap to produce and generate fuel lower in polluting sulphur and aromatic compounds than its petroleum-based equivalent. Beginning by addressing different protocols for synthesis based on fatty acids, methyl and ethyl esters, it then describes chemical analyses essential to establishing the purity of the biodiesel. It highlights in detail the use of multifunctional and synthetic antioxidants, and investigates the impact of synthetic chalcones and their derivatives on the oxidative stability of biodiesel. The author goes on to explain how to ameliorate various influences – UV irradiation and metal contaminants for example – which increase the hazards of oxidation, such as degradation and instability. New pre-treatment procedures performed using ultrasonic energies, thermostatic bath and vortex stirring are not only more environmentally friendly, but cut down on the time-consuming process of determining metal content, and allow for the use of more environmentally friendly aqueous reagents. The book investigates and demonstrates these techniques on the basis of real-world results. Further, it suggests the practical uses of byproducts of biodiesel production, for example, using glycerol as a source of energy and high valuable chemicals. These useful techniques aid any researcher exploring the production process of biodiesel and its stabilization and characteristics.

Download or read book A Guidebook to Biochemistry written by Michael Yudkin and published by Cambridge University Press. This book was released on 1980-09-25 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a completely revised and expanded edition of the Guidebook to Biochemistry. Every chapter has been reviewed and brought up to date. A new chapter, on the cell and membrane transport, has been included, and the single chapter on regulation in the previous edition has been greatly enlarged and divided into two chapters. Other topics that have received particular attention in this edition include lipids, cell membranes and the biochemical action of hormones. The chapter on genetics has been revised to take account of recent studies of the genetic organization of higher organisms, and a section on genetic engineering has been included. In making these changes the authors have taken care to adhere to the concept of the 'Guidebook' introduced by Kenneth Harrison and maintained by them in the 1971 edition: to 'introduce the reader to the important features of the subject by exemplifying and discussing crucial biochemical concepts'. For this reason they have been careful to restrict the increase in the total length of the book compared with the 1971 edition.

Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive introduction to the design, synthesis, characterization, and catalytic properties of nanoporous catalysts for the biomass conversion With the specter of peak oil demand looming on the horizon, and mounting concerns over the environmental impact of greenhouse gas emissions, biomass has taken on a prominent role as a sustainable alternative fuel source. One critical aspect of the biomass challenge is the development of novel catalytic materials for effective and controllable biomass conversion. Edited by two scientists recognized internationally for their pioneering work in the field, this book focuses on nanoporous catalysts, the most promising class of catalytic materials for the conversion of biomass into fuel and other products. Although various catalysts have been used in the conversion of biomass-derived feedstocks, nanoporous catalysts exhibit high catalytic activities and/or unique product selectivities due to their large surface area, open nanopores, and highly dispersed active sites. This book covers an array of nanoporous catalysts currently in use for biomass conversion, including resins, metal oxides, carbons, mesoporous silicates, polydivinylbenzene, and zeolites. The authors summarize the design, synthesis, characterization and catalytic properties of these nanoporous catalysts for biomass conversions, discussing the features of these catalysts and considering future opportunities for developing more efficient catalysts. Topics covered include: Resins for biomass conversion Supported metal oxides/sulfides for biomass oxidation and hydrogenation Nanoporous metal oxides Ordered mesoporous silica-based catalysts Sulfonated carbon catalysts Porous polydivinylbenzene Aluminosilicate zeolites for bio-oil upgrading Rice straw Hydrogenation for sugar conversion Lignin depolymerization Timely, authoritative, and comprehensive, Nanoporous Catalysts for Biomass Conversion is a valuable working resource for academic researchers, industrial scientists and graduate students working in the fields of biomass conversion, catalysis, materials science, green and sustainable chemistry, and chemical/process engineering.

Download or read book Preparation of Catalysts VII written by R. Maggi and published by Elsevier. This book was released on 1998-08-17 with total page 1007 pages. Available in PDF, EPUB and Kindle. Book excerpt: The proceedings of the VIIth International Symposium on the Scientific Bases for the Preparation of Heterogeneous Catalysts, are in line with the general scope of this series of events. Emphasis in all Symposia has been on the scientific aspects of the preparation of new and industrial catalysts, or on new methods of preparation, rather than on the catalytic reactions in which such solids are ultimately used. In the present context, the catalytic event itself has only been considered as another, though often decisive, method of catalyst characterization.

Download or read book Catalysis By Gold written by Geoffrey C Bond and published by World Scientific. This book was released on 2006-08-15 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gold has traditionally been regarded as inactive as a catalytic metal. However, the advent of nanoparticulate gold on high surface area oxide supports has demonstrated its high catalytic activity in many chemical reactions. Gold is active as a heterogeneous catalyst in both gas and liquid phases, and complexes catalyse reactions homogeneously in solution. Many of the reactions being studied will lead to new application areas for catalysis by gold in pollution control, chemical processing, sensors and fuel cell technology. This book describes the properties of gold, the methods for preparing gold catalysts and ways to characterise and use them effectively in reactions. The reaction mechanisms and reasons for the high activities are discussed and the applications for gold catalysis considered./a
