Process of producing hydrogen and oxygen from H2 O in a thermochemical cycle |
| abstract |
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° to 400° 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° to 1000° C. Thereupon the oxygen gas is separated from the sulfur dioxide gas in a manner known per se. |
