Available in PDF, EPUB and Kindle. Book excerpt: The sodium-hydrogen-oxygen system has been investigated in continuation of the study of impurities in liquid metals. Sodium metal reacts with sodium hydroxide at temperatures above 300 degrees C to form sodium monoxide and sodium hydride. If the reaction is initiated in vacuo, hydrogen will be liberated to the extent of the dissociation pressure of sodium hydride at temperatures below 385 degrees C. If this hydrogen is not removed from the reaction zone, and if the temperature is raised beyond 385 degrees C, an equilibrium is established which does not follow the dissociation pressure diagram for sodium hydride. This new equilibrium appears to be related to the solubility of the reaction products in sodium metal and in sodium hydroxide. The 'keystone' of the equilibrium appears to be the fusion temperature of the melt which, in turn, is determined principally by the ratio of sodium monoxide to sodium hydroxide. Data are presented showing that the dissociation of sodium hydride is suppressed by an inert gas blanket. It is indicated that sodium hydride must vaporize or sublime before it will dissociate. It is further shown that sodium hydride in solution is quite stable, even in vacuo at temperatures well above those at which the hydride should be dissociated. Data for the potassium-hydrogen-oxygen system are entirely different from that reported for the corresponding sodium system. The difference could well be related to a higher solubility of the reaction products in the reactants.(Author).

This book was released on 2012-12-06 with total page 537 pages. Available in PDF, EPUB and Kindle. Book excerpt: The international seminar "Material Behavior and Physical Chemistry in Liquid Metal Systems" was organized by the Institute of Materials and Solid State Research of the Karlsruhe Nuclear Research Center (Karlsruhe, Federal Republic of Germany). The seminar was held at the Nuclear Engineering School of the center on March 24-26, 1981. The aim of the seminar was to give metallurgists, chemists,. and physicists working in different areas of the science and technology of liquid metals an opportunity to discuss the basic work and the need for further work in this field. Since the seminar was held near one of the laboratories which for the last few years has been engaged in liquid alkali metal studies, partic ipants also had an opportunity to observe modern equipment for liquid alkali metal research. Interest in the application of liquid metals as working fluids in energy production, conversion, and storage is increasing. The technology has already demonstrated its high standards, which make possible the operation of large sodium-cooled fast reactors. Past conferences have shown, however, that there is still a lack of basic knowledge and understanding. Therefore, the aim of the present seminar was to discuss basic work in detail, and most of the papers contributed to this objective.

This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Systems, devices, and methods combine thermally stable reactant materials and aqueous solutions to generate hydrogen and a non-toxic liquid by-product. The reactant materials can sodium silicide or sodium silica gel. The hydrogen generation devices are used in fuels cells and other industrial applications. One system combines cooling, pumping, water storage, and other devices to sense and control reactions between reactant materials and aqueous solutions to generate hydrogen. Springs and other pressurization mechanisms pressurize and deliver an aqueous solution to the reaction. A check valve and other pressure regulation mechanisms regulate the pressure of the aqueous solution delivered to the reactant fuel material in the reactor based upon characteristics of the pressurization mechanisms and can regulate the pressure of the delivered aqueous solution as a steady decay associated with the pressurization force. The pressure regulation mechanism can also prevent hydrogen gas from deflecting the pressure regulation mechanism.

Book excerpt: A novel hydrogen storage material It is well known that world is running out of cheap and environmentally destructive fossil fuels in a near future. Fortunately, there are many technological options for transforming conventional fossil fuel based energy systems to less convenient but more abundant ones, such as hydrogen energy system In the present study, the quasi-binary system NaNH2 and NaBH4 was investigated with respect to phase formation and structural, thermal and vibrational spectroscopical properties, as well its capability as complex hydrogen storage material.

Available in PDF, EPUB and Kindle. Book excerpt: Sodium hydride dissolves in and reacts with molten NaOH to give an equilibrium mixture of NaH, NaOH, Na/sub 2/O, Na, and H. In the case where there is a gaseous phase (hydrogen) and only one condensed phase, the system is defined by the temperature, pressure, and one composition variable. The equilibriu, H/ sub 2/ pressure, which is a measure of the H/sub 2/ activity within the melt, was determined as a function of the composition of the condensed phase(s) at 600, 700, and 500 deg for equilibrium mixtures with original compositions of 2.5 to 97.5, 5.0 to 95.0, l0.0 to 90.0, and 20.0 to 50.0 mole% NaH-NaOH. The equilibrium H/sub 2/ pressure-composition isotherms obtained by removing measured increments of H/sub 2/ were reproduced by reabsorbing H/sub 2/. Results for the 5.0 mole % NaH mixture were duplicated by starting with an equivalent quantity of either Na in NaOH or Na/sub 2/O in NaOH, and reacting with measured increments of H/sub 2/. The system is discussed in relation to the interdependent reactions involved, the phase rule, the thermodynamics of certain reactions, and experimental techniques employed. (auth).

This book was released on 2017-07-13 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since first AC current high-power hydropower plant was put in operation, built by Nikola Tesla and George Westinghouse in 1895 on Niagara Falls, electrification of the world has dramatically changed. The growing power demand and energy consumption in the last decades require fundamental changes in the process, power production, and services. These requirements tend to use both conventional and nonconventional energy generation in order to have power plants economically useful and environmentally friendly to the society. The goal of this textbook is to provide an up-to-date review of this important topic with specific emphasis on the current guidelines for improving overall efficiency, lowering emissions, and using large share of renewable energy.
