ABSTRACT:
A method of obtaining hydrogen from water in a multi-stage circulatory process avoids the need to use solid inorganic salts as auxiliary products by using only gases and liquids in the reaction stages. Carbon monoxide is reacted catalytically with steam producing carbon dioxide and hydrogen; the carbon dioxide is reacted with steam and sulphur dioxide to give sulphuric acid and carbon monoxide; the sulphuric acid is split into sulphur trioxide and steam; the sulphur trioxide is dissociated into oxygen and sulphur dixoide. The CO and SO.sub.2 are fed back into the process, and hydrogen and oxygen obtained as end products.
