This book was released on 2014 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: A key part of the FutureGen concept is to support the production of hydrogen to fuel a 'hydrogen economy,' with the use of clean burning hydrogen in power-producing fuel cells, as well as for use as a transportation fuel. One of the key technical barriers to FutureGen deployment is reliable and efficient hydrogen separation technology. Most Hydrogen Transport Membrane (HTM) research currently focuses on separation technology and hydrogen flux characterization. No significant work has been performed on thermo-mechanical properties of HTMs. The objective of the thesis is to understand the structure-property correlation of HTM and to characterize (1) thermo mechanical properties under different reducing environments and thermal cycles (thermal shock), and (2) evaluate the stability of the novel HTM material. A novel HTM cermet bulk sample was characterized for its physical and mechanical properties at both room temperature and at elevated temperature up to 1000°C. Microstructural properties and residual stresses were evaluated in order to understand the changing mechanism of the microstructure and its effects on the mechanical properties of materials. A correlation of the microstructural and thermo mechanical properties of the HTM system was established for both HTM and the substrate material. Mechanical properties of both selected structural ceramics and the novel HTM cermet bulk sample are affected mainly by porosity and microstructural features, such as grain size and pore size-distribution. The Young's Modulus (E-value) is positively correlated to the flexural strength for materials with similar crystallographic structure. However, for different crystallographic materials, physical properties are independent of mechanical properties. Microstructural properties, particularly, grain size and crystallographic structure, and thermodynamic properties are the main factors affecting the mechanical properties at both room and high temperatures. The HTM cermet behaves more like an elastic material at room temperature and as a ductile material at temperature above 850°C. The oxidation and the plasticity of Pd phase mainly affected the mechanical properties of HTM cermet at high temperature, also as a result of thermal cycling. Residual stress induced in the HTM by thermo cycles also plays a very critical role in defining the thermo-mechanical properties.

Download or read book Technology and Uses of Liquid Hydrogen written by R. B. Scott and published by Elsevier. This book was released on 2013-10-22 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: Technology and Uses of Liquid Hydrogen deals with the technological aspects and applications of liquid hydrogen. Topics covered include the process of producing hydrogen gas for liquefaction; thermal insulation, storage, transportation, and transfer of liquid hydrogen; liquid hydrogen engines and bubble chambers; and safety in the use of liquid hydrogen. The uses of liquid hydrogen for the production of cold neutrons inside a nuclear reactor are also discussed. This book is comprised of 11 chapters and begins with a little background, history, and statistics on the technology and uses of liquid hydrogen, followed by a review of commercially feasible processes for the production of of liquid hydrogen. The reader is then introduced to the basic principles of the liquefaction of hydrogen; hydrogen liquefiers of moderate size; the use of liquid hydrogen as a coolant/propellant for nuclear rockets; and separation of deuterium by the large-scale distillation of liquid hydrogen. Subsequent chapters explore liquid hydrogen engines and bubble chambers; safety considerations in the use of liquid hydrogen; and properties of normal and para-hydrogen. This monograph will be of interest to chemists.

Book excerpt: The transport properties of hydrogen are calculated for a pressure range from 10 to the minus 6th power (atm) to 100 (atm), and at temperatures up to 10 to the 6th power (K). The lower temperature limit is taken where the equilibrium gas mixture contains less than 1% molecular hydrogen. The Boltzmann formalism, which assumes binary collisions in the expressions for the transport properties of gas mixtures, is applied. Theoretical values, supported by experimental data whenever possible are used for the atom-atom, atom-ion, and atomelectron collision cross sections. For Coulomb force interactions between charged particles, the Debye length is used as cutoff distance. The collision integrals for all interactions are computed. Values of viscosity, thermal, and electrical transport coefficients, as well as the thermoelectric coefficients are calculated. (Author).
