Online separation reforming hydrogen production method capable of enhancing reaction efficiency and device for realizing method

Abstract

The invention discloses an online separation reforming hydrogen production method capable of enhancing reaction efficiency and a device for realizing the method. A reactor of the method is composed ofinner, middle and outer concentric circular tubes made of three different materials, an upper end cover and a lower end cover, the three concentric circular tubes form three cavity channels, namely an inner cavity, a middle cavity and an outer cavity, and the upper end cover and the lower end cover are installed on the upper portion and the lower portion of the cavity channels. The lower end cover seals the lower ends of the middle cavity and the outer cavity, and the upper end cover is provided with a plurality of holes for providing a high-temperature fluid inlet for the inner cavity and providing an air inlet for the middle cavity. A high-temperature fluid flows into the inner tube to provide energy for reaction. The outer wall surface of the inner tube is coated with a catalyst. A reactant gas is introduced into the middle cavity channel; and the reactant gas and the catalyst are subjected to catalytic reaction. The middle tube is prepared by adopting different separation membranes, so that a gas product is separated into the outer cavity. And the outer cavity channel is correspondingly isolated into different gas product areas. By adopting the method provided by the invention, the conversion rate of the reactant can be remarkably improved, and the volume and weight of the whole reforming reaction system are reduced.

Description

technical field [0001] The invention belongs to the technical field of synthetic gas, and in particular relates to an on-line separation and reforming hydrogen production method capable of enhancing reaction efficiency and a device for realizing the method. Background technique [0002] Hydrogen energy is an important part of distributed energy in the future, and hydrogen refueling stations and household hydrogen are an important part of the distributed energy network in the future. At present, the vast majority of large-scale hydrogen production methods use natural gas to produce hydrogen. However, hydrogen refueling stations and household applications are not suitable for large-scale hydrogen production due to space and consumption constraints. In the future, as the layout of urban natural gas pipelines becomes more complete, considering the transportation cost and convenience of raw materials, the hydrogen production scheme using natural gas in hydrogen refueling station...
