摘要： A process for producing an isotopically enriched compound of a desired isotope includes (a) providing a cryogenic reaction zone containing a catalyst adapted to catalyze an isotope exchange reaction at a cryogenic reaction temperature, (b) feeding to the cryogenic reaction zone an enriched mixture comprising at least a compound containing the desired isotope, wherein the enriched mixture is enriched in the desired isotope above a natural abundance of the desired isotope, (c) reacting the enriched mixture in the cryogenic reaction zone thereby forming a resulting mixture containing the isotopically enriched compound, and (d) separating the resulting mixture into an enriched product which is enriched in the isotopically enriched compound and a depleted product which is depleted in the isotopically enriched compound.

摘要： This invention relates to a method for separation of isotopes, that is, to obtain isotopically pure fractions by separating natural occurring isotope mixtures in elements, where hydrogen is employed as ligand on the elements that are to be isotopically separated, and where the resulting compounds are gaseous at practical temperatures and pressures. More specific, the invention relates to a method for obtaining an isotopically pure 28SiH4 in industrial scale by separating the isotopes in a chromatographic column.

摘要： Methods and systems directed to the separation of tritium from an aqueous stream are described. The separation method is a multi-stage method that includes a first stage during which tritium of a tritium-contaminated aqueous stream is adsorbed onto a separation phase, a second stage during which the adsorbed tritium is exchanged with hydrogen in a gaseous stream to provide a gaseous stream with a high tritium concentration, and a third stage during which the tritium of the gaseous stream is separated from the gaseous stream as a gaseous tritium product.

摘要： A method of isotope enrichment including providing a reactant. The reactant is a mixture of at least two isotopic compounds. One of the isotopic compounds has a greater percentage of a selected isotope than the other. An electron transfer agent is introduced into the reactant isotope mixture to form a reaction mixture. The electron transfer agent facilitates transfer of electrons interactive with one or more selected nuclei of the reactant. The electron transfer agent is in an amount sufficient upon reaction of the reaction mixture to establish an equilibrium between an electron rich reaction product and an electron poor reaction product. The reaction mixture is reacted until the equilibrium is established. The electron poor reaction product is then separated from the electron rich reaction product.

摘要： Ein mehrstufiges Verfahren zur Abtrennung von mindestens einem schweren Isotop einer Wasserstoff enthaltenden Verbindung oder eines Wasserstoff enthaltenden Gemisches unter Verwendung einer Ammoniaksynthese und einem Wasserstoff-Stickstoffgemisch.
Hierbei wird in einem ersten Verfahrensschritt deuterium- und tritiumhaltiges Wasser mit an Tritium und Deuterium verarmten Ammoniak in Isotopenaustausch gebracht, wobei der Ammoniak-Moldurchsatz größer gewählt wird als zwei Drittel des Wasser-Moldurchsatzes.
Der Vorteil des Verfahrens besteht darin, daß als Hauptprodukt an Deuterium und Tritium mindestens weitgehend befreites Wasser gewonnen wird, wobei als weitere
Produkte an Deuterium und Tritium angereicherte Verbindungen, sowie an 15 N angereicherter Stickstoff erzeugt werden.摘要翻译： 用于分离含有氢的化合物，或使用氨合成和的氢 - 氮混合物中的含氢混合物中的至少一种重同位素的多级工艺。 在此，氘在第一工艺步骤和贫氨氚和氘同位素交换带来的氚化水，其特征在于，所述氨Moldurchsatz被选择为比水Moldurchsatzes的三分之二以上。 该方法的优点是，解放了水作为氘和氚的主要产物至少在很大程度上，由此如氘和氚富集的化合物的其它产品，以及¹<5>的N-富集的氮生成获得。
