ABSTRACT:
A process and apparatus are described for separating heavy isotopes of hydrogen. The process uses multiple protium-deuterium, protium-tritium or deuterium-tritium exchange reactions between a metal protide and gaseous hydrogen alternately depleted and enriched in at least one heavy isotope of hydrogen. The apparatus for performing the process comprises two multistage reaction zones, one for forming a metal hydride enriched in at least one heavy isotope and one for converting the enriched hydride to a depleted hydride and enriched hydrogen gas. The apparatus is simple in design and the process is much less energy intensive than existing prior art processes.
