Method for producing hydrogen for storage and transportation

摘要

Disclosed is a method for producing hydrogen for storage and transportation, by which hydrogen for storage and transportation necessary for smoothly promoting an organic chemical hydride method can be efficiently produced on a commercial scale at low cost. Specifically disclosed is a method for producing hydrogen for storage and transportation by an organic chemical hydride method, which is characterized in that: a reaction gas, which is obtained by adjusting the hydrogen concentration of a synthesis gas synthesized by a reforming reaction to 30-70 vol% by a shift reaction, is used as a hydrogen source for a reaction in a hydrogenation step of an aromatic compound; and that a hydrogenated aromatic compound is separated and purified from the reaction mixture that is obtained in the hydrogenation step.
