    • A method of producing hydrogen. A supply of sodium hydroxide, which constitutes a first composition (11), is received in cavity (21) which is defined by container (13). The sodium hydroxide (11) travels to the chemical reactor (30) by way of conduit (31). A second composition (40), which provides a source of hydrogen, such as methane, may react with the first composition in order to release hydrogen which is utilized to form a resulting chemical hydride. The second composition or source of methane (40) is coupled in fluid flowing relation with chemical reactor (30), by way of conduit or passageway (41). The byproducts produced by the chemical reaction of the first and second compositions (11 and 40) may include undesirable compositions such as carbon monoxide. Consequently, a shift converter (50) is provided, and the byproducts which may include carbon monoxide are supplied to shift converter (50) where the carbon monoxide is chemically converted to carbon dioxide. The shift converter (50) is coupled to the chemical reactor (30) by way of a conduit or passageway (51).
    • 一种生产氢气的方法。 构成第一组合物(11)的氢氧化钠供应源容纳在由容器(13)限定的空腔(21)中。 氢氧化钠(11)通过导管(31)行进到化学反应器(30)。 提供氢源例如甲烷的第二组合物(40)可与第一组合物反应以释放用于形成所得化学氢化物的氢。 甲烷(40)的第二组合物或来源通过导管或通道(41)与化学反应器(30)流体连接。 第一和第二组合物(11和40)的化学反应产生的副产物可能包括不需要的组合物,如一氧化碳。 因此,提供了转换器(50),并且可以包括一氧化碳的副产物被供应到转化器(50),在转化器(50)中一氧化碳被化学转化为二氧化碳。 变换器(50)通过导管或通道(51)连接到化学反应器(30)。

    • The invention includes a method of separating isotopes from a mixture containing at least two isotopes in a solution. A first isotope is precipitated and is collected from the solution. A daughter isotope is generated and collected from the first isotope. The invention includes a method of producing an actinium-225/bismuth-213 product from a material containing thorium-229 and thorium-232. A solution is formed containing nitric acid and the material and iodate is added to form a thorium iodate precipitate. A supernatant is separated from the thorium iodate precipitate and a second volume of nitric acid is added to the precipitate. The precipitate is stored and a decay product comprising actinium-225 and bismuth-213 is generated in the second volume of nitric acid which is then separated from the thorium iodate precipitate, filtered, and treated using at least one chromatographic procedure. The invention also includes a system for producing an actinium-225/bismuth-213 product.
