Method for producing hydrogen by reforming methanol steam

The invention relates to a method for producing hydrogen by reforming methanol steam. The method comprises the following steps: taking methanol and water as raw materials, enabling the reaction temperature to be 410-460 DEG C, enabling the reaction space velocity to be 3000-23000h<-1> (calculated based on gaseous methanol), mixing the raw materials of the methanol and the water under the condition that the molar ratio of methanol to the water is 1: (0.8-2.0) for vaporization, then enabling the mixture to be in contact with a ZnO / ZnAl2O4 catalyst in a fixed bed reactor, generating reformed gaswhich is rich in the hydrogen, and separating the reformed gas by a palladium membrane separator for producing pure hydrogen gas. In the ZnO / ZnAl2O4 catalyst, the zinc-aluminum atomic ratio is more than 0.5: 1 and less than 2.5: 1. The method has the advantages of high reaction space velocity, high reaction conversion rate and low CO concentration, and the catalyst is simple to prepare, good in stability, low in cost and the like, thereby being particularly applicable to the process of integrating the hydrogen production by reforming the methanol steam with palladium membrane separation for preparing the pure hydrogen, and being capable of being used for industrial production process.
