    Abstract: A process is disclosed which produces hydrogen and oxygen from water by means of a multi-step, closed, thermochemical cycle. Hydrogen and oxygen are produced at separate stations. Hydrogen and a halogen are produced by a sub-cycle involving transition metal or lanthanide compounds (depending on the halogen) and a hydrogen halide. Oxygen and the hydrogen halide are produced in a sub-cycle involving magnesium or transition metal compounds (depending on the halogen), the halogen and water. When the halogen is chlorine the transition metals in the oxygen producing sub-cycle can be nickel, cobalt, or yttrium and the lanthanide metals in the hydrogen producing sub-cycle can be samarium, europium, or ytterbium. When the halogen is bromine, the metals in the oxygen producing sub-cycle can be manganese or cobalt and the metals in the hydrogen producing sub-cycle can be vanadium or chromium.

    Abstract: An apparatus for using solar energy to manufacture hydrogen by dissociating water molecules into hydrogen and oxygen molecules. Solar energy is concentrated on a globe containing water thereby heating the water to its dissociation temperature. The globe is pervious to hydrogen molecules permitting them to pass through the globe while being essentially impervious to oxygen molecules. The hydrogen molecules are collected after passing through the globe and the oxygen molecules are removed from the globe.

    Abstract: A process for the recovery of deuterium from a gas having deuterium values and oxygen bearing impurities by contacting the gas with a solution of sodium or lithium in ammonia to eliminate oxygen-bearing impurities as sparingly soluble reaction products. The NH3-Na or Li solution contacts the synthesis gas saturated with NH3 having oxygen impurities and deuterium values therein and the deuterium rich ammonia gases from a deuterium enrichment unit in order to achieve saturation of higher deuterium concentration. The ammonia gases saturated with deuterium values are finally passed on to the deuterium enrichment unit to recover deuterium values and to produce ammonia depleted of deuterium. The preparation and/or stock tank for the Na -or Li- solution in NH3 is provided with a lining material selected from the group consisting of copper, non-ferrous metal and plastics because the NH3-Na solution resides in these containers for an extended period of time.
