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

摘要

PROBLEM TO BE SOLVED: To provide a method for extracting hydrogen energy from aqueous ammonia by making effective utilization of waste containing ammonia nitrogen.SOLUTION: A method for producing ammonia decomposition hydrogen is a method for producing hydrogen by decomposition of ammonia, comprising: a separation step of separating ammonia from waste containing ammonia nitrogen; a concentration step of concentrating ammonia separated in the separation step to obtain aqueous ammonia; and an ammonia decomposition step of spraying the aqueous ammonia onto a catalyst layer to decompose ammonia into hydrogen and nitrogen.SELECTED DRAWING: Figure 1
