O-21　鶏糞からのアンモニア生成に関する尿酸とタンパク質の水熱反応挙動

抄録

In recent years, livestock excreta has begun to be utilised by technologies such as methane fermentation, but the nitrogen content in livestock excreta inhibits the reaction of methane fermentation. Therefore, it was decided to convert the nitrogen into ammonia by hydrothermal pre-treatment to recover it. When the feedstock was chicken manure, the ammonia production behaviour by hydrothermal treatment could not be identified. Therefore, uric acid and protein, which are abundant as nitrogen sources in chicken manure, were treated and analysed by themselves. By confirming these behaviours, the reaction pathway of chicken manure was made clearer.
