Book Description
Supercritical Fluid Technology for Energy and Environmental Applications covers the fundamental principles involved in the preparation and characterization of supercritical fluids (SCFs) used in the energy production and other environmental applications. Energy production from diversified resources — including renewable materials — using clean processes can be accomplished using technologies like SCFs. This book is focused on critical issues scientists and engineers face in applying SCFs to energy production and environmental protection, the innovative solutions they have found, and the challenges they need to overcome. The book also covers the basics of sub- and supercritical fluids, like the thermodynamics of phase and chemical equilibria, mathematical modeling, and process calculations. A supercritical fluid is any substance at a temperature and pressure above its critical point where distinct liquid and gas phases do not exist. At this state the compound demonstrates unique properties, which can be "fine-tuned," making them suitable as organic solvents in a range of industrial and laboratory processes. This volume enables readers to select the most appropriate medium for a specific situation. It helps instructors prepare course material for graduate and postgraduate courses in the area of chemistry, chemical engineering, and environmental engineering. And it helps professional engineers learn supercritical fluid-based technologies and use them in solving the increasingly challenging environmental issues. Relates theory, chemical characteristics, and properties of the particular supercritical fluid to its various applications Covers the fundamentals of supercritical fluids, like thermodynamics of phase and chemical equilibria, mathematical modeling, and process calculations Includes the most recent applications of supercritical fluids, including energy generation, materials synthesis, and environmental protection

Book Description
This text presents the latest advances in supercritical fluid technology, biocatalysis, bioprocess engineering, and crop breeding. It offers an in-depth review of the most recent principles and approaches utilized in the development and design of lipids for cosmetic, industrial and pharmaceutical, and food products. Discussing a variety of lipid-active enzymes from animal, plant, fungal, and microbial sources, "Lipid Biotechnology" covers modern techniques in genetic engineering for the modification of conventional oilseed crops and biosynthetic pathways for cutin polymers, flavor volatiles, oxylipins, and terpenoid compounds. It chronicles the use of lipases and phospholipases in the creation of structured lipids and fats, including cocoa butter, low-calorie fats, and Betapol, and emerging methods using supercritical carbon dioxide as a benign solvent for lipid analysis, fractionation, and enzymatic reaction. It also covers reaction conditions, reactor design, solvent selection, immobilization technology, and enzyme sources for optiml large-scale manufacturing, and describes the formation of oxylipins through the lipoxygenase pathway, as well as other unusual fatty acids. The authors provide in-depth analyses of the structure, metabolic and enzymatic functions and mechanisms, defensive and catalytic properties, industrial uses, and other applications of oxilipins and lipases.

Book Description
Supercritical Fluid Extraction is a technique in which CO2 is used under extremely high pressure to separate solution (e.g., removing caffeine from coffee). Separations is basic to all process industries and supercritical fluid extraction is a specific type which is receiving a high level of attention. The book will combine basic fundamentals with industrial applications. The second edition has been expanded and updated and includes new chapters on chromatography and food processing. "...this is an excellent book which is both instructive and amusing to read. Its true value is neatly summarised in one of the closing sentences: 'We have supplied you with the guidelines and criteria which you can now apply when considering supercritical fluids for your own needs.'' - Chemistry in Britain, February 1995

Book Description
Enzymes are currently used in various industries, most commonly in food, detergents, and pharmaceuticals production. Lipases are hydrolytic enzymes that demonstrate great potential as an alternative to conventional catalysts in a number of industrial applications. A complete understanding of enzymes, and their proteins structure and environmental behavior, can greatly aid in the further development of industrial applications. Supercritical Fluids Technology in Lipase Catalized Processes provides basic information about enzymes, their sources, reaction kinetics, and main industrial applications. The book focuses in lipases. their main sources, structure, and features, with an emphasis on their specificity and interfacial activity, and presents proven techniques for isolating, extracting, and purifying. Comprised of six compact chapters, this comprehensive guide introduces: Immobilization techniques and immobilized lipases that allow repeated use (which is essential from an economic point of view) Different bioreactor configurations using immobilized lipases The latest information on the available technologies in lipolytic reactions The advantages of nonaqueous media in biochemical synthesis over aqueous and solvent-free systems Material on the use of lipases in nonaqueous media to overcome the drawbacks usually encountered with the use of conventional chemical catalysts The use of supercritical fluids (SCFs) as a green alternative reaction medium Factors affecting the physical properties of lipases in this medium and, hence, their activity and stability A case study using supercritical carbon dioxide (SC-CO2) for biodiesel production Novel, cutting-edge technology, using immobilized enzymes to reduce the overall production cost Supercritical Fluids Technology in Lipase Catalized Processes outlines the main industrial applications of common enzymes and discusses relevant challenges and innovations emerging in the field.

Book Description
The aim of this book is to present the fundamentals of high pressure technologies from the perspective of mass transfer phenomena and thermodynamic considerations. Novel food applications are exposed and their relation to chemical analysis, extraction, reaction and particle formation processes are outlined. The chapters are written by a diverse group of scientists with expertise in chemistry, food processes, analytical chemistry, chemical engineering and chemical engineering thermodynamics, and biotechnology. The mission of green food engineering is to promote innovative technologies that reduce or eliminate the use or generation of hazardous materials (solvents, reagents) in the design and operation of food related processes, with the view to improve food safety and quality. Several efficient, environmentally friendly and benign technologies based on the use of high pressure and green solvents have demonstrated to be sustainable alternatives to traditional processes in the food industry. Although hundreds of new ideas are being published in the open literature, reliable engineering tools to simulate and design those processes are still under development. High Pressure Fluid Technology for Green Food Processing presents in-depth analyses and outlines the ways towards their maturity.
