| 摘要 |
The present invention relates to a method for controlling hydrogen purification for alkali water electrolysis that can improve the purification efficiency of a hydrogen gas by catalyst-reacting an impurity-including raw material gas that is supplied from an alkali water electrolysis device and by alternately performing a moisture adsorption reaction for a catalyst reactive gas including moisture and a reproduction reaction for desorbing adsorbed moisture in a plurality of adsorption reactors. To this end, the method of the present invention comprises the steps of: producing moisture by means of an oxygen catalyst reaction that is performed on oxygen included in a raw material gas by feeding a hydrogen gas that is supplied from an alkali water electrolysis device into a catalyst reactor; supplying the produced moisture to a first adsorption reactor; supplying the produced moisture to a second adsorption reactor and a recycled gas to the first adsorption reactor if an adhesive layer of the first adsorption reaction is saturated; and controlling an adsorption reaction and a reproduction reaction alternately in the first adsorption reactor and second adsorption reactor until a hydrogen gas having desired purity is obtained. |
