Abstract

The invention provides a hydrogen adsorber regeneration system and method wherein the regeneration system comprises: a first gas supply unit for providing hydrogen to be treated; the adsorption unit is connected with the first gas supply unit and comprises at least a first adsorber and a second adsorber which can be switched for use, and when the first adsorber carries out adsorption, the second adsorber carries out regeneration; the regeneration gas supply unit is connected with the adsorption unit and is used for providing regeneration gas for the second adsorber so as to discharge impurity gas generated during regeneration of the second adsorber by utilizing the regeneration gas; the high-purity hydrogen supply unit is connected with the adsorption unit and is used for providing high-purity hydrogen in a preset temperature range for the second adsorber so as to discharge regenerated gas in the second adsorber by utilizing the high-purity hydrogen; and the discharge unit is connected with the adsorption unit and is used for at least discharging the impurity gas and the regenerated gas in the second adsorber. The hydrogen adsorber regeneration system provided by the invention can improve the regeneration depth of the hydrogen adsorber.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of hydrogen liquefaction, and in particular, to a hydrogen adsorber regeneration system and a method thereof. Background technique [0002] The utilization of hydrogen energy can solve the problems of sustainability, pollution emissions and energy security. In recent years, hydrogen energy has been widely used in the fields of national defense, aerospace, scientific engineering research, low temperature superconductivity, electronic chips, energy chemical industry, metallurgy and energy transportation. However, due to the storage and transportation problems of hydrogen energy, the commercial application cost of hydrogen energy remains high. We know that liquefied hydrogen (LH 2 ) has an energy density of almost 4.5 times that of compressed hydrogen at 200 bar, and if large quantities of hydrogen energy are transported from remote areas to urban hydrogen refueling stations, the storage...
