Abstract
A process for manufacturing hydrogen by reducing tin oxide in a reducing zone at about 1000.degree. to about 1200.degree.C. with a reducing gas to form molten tin, feeding the molten tin as a spray into an oxidizer zone containing steam maintained at about 400.degree. to about 650.degree.C. and at about 1000 to about 2500 psig, whereby the reaction of the tin with the steam forms hydrogen and tin oxide, separating hydrogen product under pressure and recycling the tin oxide to the reducing zone.
