A method of hydrogen production

This method of producing hydrogen from water in a multistage cycle process works without anorganic salts and requires only gases and liquids. Carbon oxide is catalytically converted into carbon dioxide and water by means of water vapour. The carbon dioxide is then converted into sulphuric acid and carbon oxide using water and sulphur dioxide at high temperatures and pressures, and the sulphuric acid is separated into sulphur dioxide, oxygen and water via the intermediate SO2. The SO2 and CO2 thus obtained are led back into the appropriate reaction stages, and hydrogen and oxygen are removed from the process as end products. (A schematic flow diagram is given.) (UWI)
