Device and method for preparing hydrogen by the electrocatalysis water vapour recapitalization biological oil

The invention relates to a technology of electrocatalysis reforming of an organic compound, in particular to a hydrogen producing method of the electrocatalysis steam reforming of bio-oil and a corresponding device, which comprises a cylindrical reactor with a reforming catalyst and an outer heating furnace. The invention is characterized in that a bio-oil storage tank and a steam producer are communicated with an inlet pipeline with a preheating device; a tail gas collecting and purifying system is arranged on an output pipeline, an electric stove heating wire is arranged in the intra-cavityof the reactor. While in use, the external power of the electric stove heating wire is switched on first to heat the catalyst, then a fluid mixture of bio-oil and steam is piped into the intra-cavityof the reactor, enabling the electrocatalysis steam reforming and the water-gas convention to react in the steam atmosphere and mid-temperature environment, and to transform the C-H-O organic matter to a mixture gas of hydroge
