熱分解油(バイオオイル)の性状評価法の検討

摘要

Fast pyrolysis of biomass resources served three valuable phases; gas, liquid and solid. The liquid product, called as pyrolysis oil or bio-oil, has been getting more attentions owing to its high potentials as a renewable liquid biofuel and/or a new biomass-based material. To promote further studies on its relative technologies, developments of common indexes for its performance evaluations are really important. In this reports, our recent approaches to elucidate physical properties (solubility, CHNS values, calorific value, water content, viscosity, pH, acidity, etc) and spectroscopic and/or mass characters obtained by Fourier-transform infrared (FT-IR), nuclear magnetic resonance (~(13)C-NMR), gas chromatography-mass (GC-MS), high-resolution Fourier-transform ion cyclotron resonance mass (FT-ICRMS) spectrometry and other analytical methods would be discussed on the basis of actual analytical data of the bio-oils produced by our developing pyrolytic reactors.%在来型資源の使用による地球環境への悪影響が懸念されており，再生可能で多様な天然炭素資源の利点を活かした新しい資源·エネルギー供給体系の構築が切望されている。木質系バイオマスは，再生可能でカーボンニュートラルな資源·エネルギー源であり，そのー端を担うキーマテリアルの一つとして注目されている。
