METHOD AND APPARATUS FOR PRODUCING HYDROGEN

摘要

To improve heat resistance of a reactor which is used in an autothermal reforming process wherein a hydrocarbon is reacted with water and oxygen. A reactor (2) comprises: a gas feed port (3) for introducing a gas that contains a hydrocarbon and oxygen; and a peripheral wall (5) that forms a reaction region (2a) for the hydrocarbon and oxygen in the downstream of the gas feed port (3). Water vapor for cooling the peripheral wall (5), which is heated by the reaction heat between the hydrocarbon and oxygen in an autothermal reforming process, is introduced into the reaction region (2a) from the outside of the peripheral wall (5) through a water vapor channel that penetrates through the inner and outer peripheral surfaces (5b, 5a) of the peripheral wall (5). The water vapor that has cooled the peripheral wall (5) is used as at least some of the water vapor to be reacted with the hydrocarbon in the autothermal reforming process.
