    • A method of producing hydrogen and oxygen by splitting water in a thermocical cycle, according to which in a first method stage a gas mixture of from 1 to 50 parts by volume of steam and 2 parts by volume of sulfur dioxide is reacted at a temperature within the temperature range of from 200.degree. to 400.degree. C with an oxide of one of the metals manganese, iron, cobalt, nickel, zinc or cadmium for forming a metal sulfate and for freeing hydrogen gas. Thereupon the hydrogen gas is in a manner known per se separated from the residual gas mixture and in a second method stage after conversion of the metal oxide to a metal sulfate, the metal sulfate for purposes of decomposition or disintegration and for forming a metal oxide, sulfur dioxide gas and oxygen gas, is heated to a temperature within the temperature range of from 700.degree. to 1000.degree. C. Thereupon the oxygen gas is separated from the sulfur dioxide gas in a manner known per se.
    • 一种通过在热化学循环中分解水来产生氢和氧的方法,根据该方法,在第一方法阶段,将1至50体积份蒸汽和2体积份二氧化硫的气体混合物在 温度范围为200-400℃,与金属锰,铁,钴,镍,锌或镉之一的氧化物形成金属硫酸盐并释放氢气。 因此,氢气以本身已知的方式与残留气体混合物分离,并且在将金属氧化物转化为金属硫酸盐之后的第二方法阶段中,金属硫酸盐用于分解或分解和用于形成金属氧化物, 二氧化硫气体和氧气被加热至700℃至1000℃的温度范围内。然后以本身已知的方式将氧气与二氧化硫气体分离。
