Abstract
The present application provides a system and a method for water-based chemical-looping hydrogen generation. The method for water-based chemical-looping hydrogen generation comprises a water-based reduction process of oxygen carrier and a water-based oxidation process of oxygen carrier, wherein in the water-based reduction process of oxygen carrier, an oxygen carrier is reduced with a hydrocarbon fuel in the presence of a steam to produce a hydrogen gas as well as a reduced oxygen carrier and a carbon dioxide; and in the water-based oxidation process of oxygen carrier, the reduced oxygen carrier is oxidized with the steam to produce the hydrogen gas, while the reduced oxygen carrier is oxidized to its original state, thereby forming a chemical-looping. The present application can reduce the energy consumption while improving the efficiency of the hydrogen generation, enabling a zero energy consumption separation of carbon dioxide in the hydrogen generation process.
