| Outline of Final Research Achievements |
To improve the efficiency of biomass gasification, a series of research on reaction prediction methods and measurement methods of multi-component gas mixture generated upon biomass gasification were performed. The main achievements can be sumerized as: (1) The first comprehensive chemical kinetic model of lignin, which uses only the elemental composition as input information, is used to quantitatively predict the thermal decomposition of lignin including both primary and secondary pyrolysis. (2) Ion attachment mass spectrometry using Li+ ions was applied for the first time to real-time quantitative analysis of volatile components generated by solid fuel pyrolysis, and succeeded in fragment-free measurement of volatile which exhibit multi-component gas mixtures.

本研究は、まず初期熱分解反応モデルの妥当性をモデルによる予測と熱分解実験結果との比較によって検証した。次いで、計算化学に基づきモノリグノール二次気相分解の詳細化学反応モデルを構築し、これを初期熱分解の反応モデルに加えることによって生成物組成の予測精度が向上することを明らかにした。加えて、Li+付着イオン化質量分析法を揮発成分のリアルタイム定量分析に初めて適用し、多成分混合物である揮発成分のフラグメントフリー計測に成功した。本研究で得られた新知見や提案された計測手法は、バイオマス熱化学転換の基盤技術として有用であり、炭素資源利用に関する化学反応工学の発展に寄与する。
