Hydrogen production method

摘要

The present invention provides a method of efficiently reforming an automotive fuel and producing hydrogen continuously at high selectivity and high yield even under conditions of low A/F ratio in the reforming of the automotive fuel using autothermal reforming, and the like., can efficiently reform and produce hydrogen even under conditions of low A/F ratio by using oxygen-enriched air and water vapor in reforming reactions of an automotive fuel and adjusting the molar ratio of the water vapor with respect to the carbon atoms in the automotive fuel to reform the automotive fuel.
