Abstract

The invention relates to the technology of electrocatalytic reforming of organic compounds, in particular to a method and device for producing hydrogen from bio-oil by electrocatalytic steam reforming. The device includes a cylindrical reactor with a reforming catalyst and an external heating furnace, a bio-oil storage tank, a steam generator connected to an inlet pipeline with a preheating device, and a tail gas collection and purification system on the output pipeline. An electric furnace wire is arranged in the inner cavity of the device. When producing hydrogen, the external power supply of the electric furnace wire is first connected to heat the catalyst; then the mixed fluid of raw bio-oil and water vapor is passed into the inner cavity of the reactor, so that the bio-oil can be electrocatalyzed by water in a water vapor atmosphere and a medium temperature environment. Steam reforming reaction and water gas shift reaction convert carbon-hydrogen-oxygen-containing organic matter into hydrogen and carbon dioxide mixed gas. The invention utilizes heating electric furnace wire to provide hot electrons for the catalyst surface to dissociate and degrade various complex carbon-hydrogen-oxygen macromolecules in bio-oil, and obtain high hydrogen yield and bio-oil conversion under the condition of 450-550°C Rate.

Description

technical field

[0001] The invention relates to the technology of electrocatalytic reforming of organic compounds, in particular to a method and device for producing hydrogen by electrocatalytic steam reforming of biological oil. Background technique

[0002] Energy is an important pillar for human survival and sustainable social and economic development. With the rapidly increasing pressure of energy demand and environmental protection, the utilization of renewable biomass energy has received great attention. Hydrogen is currently one of the most ideal clean energy sources with high calorific value. Biomass has become a promising source of hydrogen due to its abundant resources, environmental friendliness, and renewable advantages. Liquid bio-oil is an organic liquid mixture produced by rapid pyrolysis and liquefaction of biomass. Bio-oil has the advantages of easy collection, storage and transportation. Compared with direct biomass gasification, bio-oil is more easily cat...
