Abstract
The invention relates to a method for producing gaseous hydrogen and strong sulphuric acid (97-100 wt-%) simultaneously from sulphur dioxide gas and water. Sulphur dioxide gas stream is divided into two separate sub-streams, the first sub-stream is routed for water decomposition in a partial thermochemical cycle of the hydrogen and sulphuric acid production and the second sub-stream is fed to the oxidation of the sulphur dioxide to sulphur trioxide.
