Abstract
A method is disclosed for heavy-water extraction from non-electrolytic hydrogen streams using a modified Combined Electrolysis and Catalytic Exchange-Heavy Water Process (CECE-HWP). The method comprises contacting feed water in a catalyst column with hydrogen gas originating partly from such non-electrolytic hydrogen stream and partly from an electrolytic hydrogen stream so as to enrich the feed water with deuterium extracted from both the non-electrolytic and electrolytic hydrogen gas, and passing the deuterium enriched water to an electrolyzer wherein the electrolytic hydrogen gas is generated and then fed through the catalyst column.
Claims7
A method for heavy-water extraction from non-electrolytic hydrogen streams using a combined electrolysis and catalytic exchange heavy-water process, comprising:
- (a) contacting feed water in a catalyst column with hydrogen gas originating partly from said non-electrolytic hydrogen stream and partly from an electrolyte hydrogen stream so as to enrich the feed water with deuterium present in the hydrogen gas;
- and
- (b) passing the enriched feed water to an electrolyser wherein the electrolytic hydrogen gas is generated and then fed through the catalyst column.
