Claim Text:
1. Method for producing and regenerating a metallic alkali alloy, wherein salts, hydroxides, alkoxides or oxides of alkali metals selected from the group consisting of alkali, nitrates, carbonates, formiates, oxalates, and acetates are mixed with oxides of semi-metals, non-metals or metals, selected from the group consisting of CO to form a mixture and the mixture is subsequently heated to at least 400° C. such that the metallic alkali alloy is formed, the salts, hydroxides, alkoxides or oxides of alkali metals being present in a molar ratio of 1:1 or in excess thereof in relation to the oxides of the semi-metals, non-metals or metals, wherein the metallic alkali alloy is subjected to a plurality of soot-combustion cycles by application of soot followed by thermal combustion of the soot at 300° C. which causes the amount of metallic alkali alloy in the mixture to diminish, and wherein the diminished alkali alloy mixture is heated to 500° C. such that the metallic alkali alloy is regenerated.
