Thermochemical process for the production of hydrogen and oxygen from water

摘要

In a thermochemical circulation process, hydrogen and oxygen are obtained from water wherein sulfuric acid and the paraffin hydrocarbon corresponding to the olefin used are formed from water, sulfur dioxide and a low-molecular weight olefin, particularly ethylene; the sulfuric acid is decomposed into water, sulfur dioxide and oxygen; the paraffin hydrocarbon is decomposed into the corresponding olefin and hydrogen; and after the removal of the hydrogen and oxygen, the remaining separation products are recycled into the first reaction.
