METHOD FOR PRODUCING HYDROGEN FROM AMMONIA NITROGEN-CONTAINING WASTE BY AMMONIA DECOMPOSITION

摘要

The present invention provides a method for producing hydrogen by decomposing ammonia for the purpose of providing a method for effectively utilizing waste that contains ammonia nitrogen and taking a hydrogen energy out of ammonia water. This method for producing hydrogen by ammonia decomposition comprises: a separation step for separating ammonia from waste that contains ammonia nitrogen; a concentration step for obtaining ammonia water by concentrating the ammonia separated in the separation step; and an ammonia decomposition step for decomposing the ammonia water into hydrogen and nitrogen by spraying the ammonia water on a catalyst layer.
