Abstract
Methods and systems for generating sulfuric acid () are disclosed. In some embodiments, the method includes combusting a sulfur-containing material () with a gas including oxygen () to produce a first stream of sulfur dioxide (), mixing water with the first stream of sulfur dioxide to produce a mixed stream, using an energy, electrolytically converting () the mixed stream of sulfur dioxide and water into sulfuric acid () and hydrogen (), generating a source of energy () from the hydrogen, and providing the source of energy as at least a portion of the energy for electrolytically converting the first stream of sulfur dioxide and water into sulfuric acid and hydrogen. In some embodiments, the system includes a first chamber for combusting a sulfur-containing material to produce a first stream of sulfur dioxide, an electrolytic cell () for converting the first stream into sulfuric acid and hydrogen, and a fuel cell () for generating an energy source from the hydrogen.
