50 畜産廃棄物コンポスト熱分解時における含窒素化合物放出挙動(バイオマス)

In order to reveal the fate of N-containing compounds in manure compost upon pyrolysis, the manure compost has been pyrolyzed at various temperatures with fixed bed reactor. And the samples were characterized with XPS. About 80% of the nitrogenous substance in the manure compost was an amine-N and/or nitrile-N. The amount of volatile-N increases with the increase of the pyrolysis temperature, and it corresponds with decrease of amine-N/nitrile-N. The conversion to cyanogen is 3% while fuel-N of about 25% converts to NH_3, at 900℃ pyrolysis temperature.
