Описание: This text examines supercritical fluids which can be compressed from low to high density, and are gaining importance as tunable solvents and reaction media in the chemical process industry. By adjusting the pressure, the properties of these fluids are manipulated for the process at hand.
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.
Описание: The use of supercritical fluids in analytical chemistry is still grow- ing. The advantages of supercritical CO , such as having dif- 2 fusivity like a gas and solvating power depending on temperature and pressure, are also valid for other fluids and modified fluids.

Описание: Materials for Ultra-Supercritical and Advanced Ultra-Supercritical Power Plants provides researchers in academia and industry with an essential overview of the stronger high-temperature materials required for key process components, such as membrane wall tubes, high-pressure steam piping and headers, superheater tubes, forged rotors, cast components, and bolting and blading for steam turbines in USC power plants. Advanced materials for future advanced ultra-supercritical power plants, such as superalloys,new martensitic and austenitic steels, are also addressed. Chapters on international research directions complete the volume. The transition from conventional subcritical to supercritical thermal power plants greatly increased power generation efficiency. Now the introductions of the ultra-supercritical (USC) and, in the near future, advanced ultra-supercritical (A-USC) designs are further efforts to reduce fossil fuel consumption in power plants and the associated carbon dioxide emissions. The higher operating temperatures and pressures found in these new plant types, however, necessitate the use of advanced materials.
