THE PROCESS FOR SEPARATING DEUTERIUM FROM A GASEOUS FEED STREAM OF MIXED HYDROGEN AND DEUTERIUM, THAT INCLUDES REACTING SAID MIXTURE UNDER SUPERATMOSPHERIC PRESSURE IN THE RANGE OF ABOUT 0.5 TO 10 ATMOSPHERES GAUGE WITH MOLTEN ALKALI METAL TO FORM ALKALI METAL HYDRIDE PREFERENTIALLY RETENTIVE OF HYDROGEN AS COMPARED WITH DEUTERIUM, SEPARATING A STREAM CONTAINING THE ALKALI METAL HYDRIDE FROM THE DEUTERIUM-ENRICHED GASEOUS RESIDUE, REDUCING THE PRESSURE OF SAID STREAM TO AT LEAST PARTIALLY DISSOCIATE THE HYDRIDE, HEATING THE REDUCED PRESSURE STREAM BY HEAT RESULTING FROM THE EXOTHERMIC REACTION OF SAID GASEOUS MIXTURE WITH THE ALKALI METAL, SEPARATING MOLTEN ALKALI METAL FROM THE REDUCED PRESSURE STREAM SO HEATED, AND RECIRCULATING THE SEPARATED ALKALI METAL FOR REACTION WITH SAID GASEOUS STREAM OF HYDROGEN AND DEUTERIUM.
