    摘要: LITHIUM-DOPED AMORPHOUS BERYLLIUM HYDRIDE SLURRIED WITH RELATIVELY SMALL AMOUNTS OF AN INERT LIQUID SLURRY MEDIUM CAN BE CRYSTALLIZED BY EXPOSURE FOR A SUFFICIENT TIME TO ELEVATED TEMPERATURE AND PRESSURE. SUITABLE SOLVENTS ARE HIGH-BOILING HYDROCARBONS. A VITREOUS COMPOSITE SUITABLE FOR USE IN THIS CRYSTALLIZATION PROCESS CAN BE PREPARED BY COMPRESSING LITHIUM-DOPED, AMORPHOUS BERYLLIUM HYDRIDE AND HEATING THE RESULTING COMPACT.

    摘要: A process is provided for recovering oxygen from air and particularly providing a product stream comprising a mixture of oxygen and steam useful, for example, in coal gasification processes. The instant process involves contacting a suspension of manganese dioxide in an aqueous solution of sodium or potassium hydroxide with air in a low pressure absorbing zone. The resulting liquid oxygen enriched stream is then pumped into a relatively high pressure generating zone where it is contacted with steam to release oxygen absorbed in the absorbing zone and thereby provide the above mentioned product.

    摘要: A chemical separator for extracting oxygen from air having a ram air inlet opening into a venturi. High velocity, high temperature venturi air is ducted into the high pressure chambers of a plurality of radially disposed, peripherally driven, cylinders or drums rotated by air turbines. The cylinders are divided into high and low pressure chambers by a stationary panel fixed at its opposite ends to the frame of the separator. Cylinders are of double wall construction having a multiplicity of screened openings therein. Chemicals are contained between the cylinder walls for collecting and discharging oxygen as the chemicals are cycled between the high and low pressure chambers of the cylinders. Heat exchangers positioned in the low pressure chambers of the cylinders, cool the oxygen released by the chemicals to a liquid state for convenience in storage or direct ducting to a power plant.

    摘要: Process of preparing special oxygen acceptor compositions for the production of oxygen in modified Brin-type processes. The preparation process comprises forming a physical mixture of finely ground barium carbonate and a composition or compound containing Mg and Ca carbonates, e.g., dolomite, in predetermined proportions, and heating them under an inert gas, such as nitrogen, or in a vacuum to convert the barium carbonate to barium monoxide and the dolomite dolomitic quicklime. Thereafter, the composition is heated in a dry, CO2-free atmosphere of air or oxygen to convert the barium monoxide to barium peroxide to form the final composition of barium peroxide-dolomitic quicklime. Pellets, powders, granules and coatings of the material may be formed. The mixture may be pelletized before or after either conversion step. Other decomposable compounds of magnesium and calcium may be used in place of the preferred dolomite. The end product compositions should have a carbon dioxide level such that the CO2/BaO2 mole ratio in the mixture is less than 1.0. Modified Brin-type processes employing pellets of this composition show improved oxidation and reduction rates and SORT conversion values for times in excess of typical static bed cycle time or fluidized bed residence time.

    摘要: A selective method of removing sulfur dioxide from flue gases or the like containing both sulfur dioxide and hydrogen sulfide without removing the hydrogen sulfide by bubbling the flue gas through about a 5-95 percent solution of an organic acid and an alkali metal salt of the said acid.
