Abstract
The present disclosure relates to a pressure swing adsorption apparatus for high purity hydrogen purification from ammonia decomposition and a hydrogen purification method using the same, and more specifically, the pressure swing adsorption apparatus includes a plurality of adsorption towers including a guard bed unit and a hydrogen purification unit, in which each adsorption tower is packed with different adsorbents, to purify high purity hydrogen from mixed hydrogen gas produced after ammonia decomposition, make it easy to replace the adsorbent for ammonia removal, minimize the likelihood that the lifetime of the adsorbent in the hydrogen purification unit is drastically reduced by trace amounts of ammonia, efficiently recover hydrogen of the guard bed unit, thereby maximizing the hydrogen recovery rate compared to a conventional pressure swing adsorption process including a pretreatment unit and a hydrogen purification unit, and respond to a large change in ammonia concentration in the raw material.
