49.ヨウ化リチウムの添加が褐炭の加熱変化過程に及ぼす影響

抄録

Effects of lithium iodide doping on devolatilization characteristics of two kinds of brown coals were investigated by in-situ FT-IR. The spectra were resolved into several absorptionpeaks on the basis of hydrogen-bond strength. The doping resulted in a shift of the peaks arisen from weakly hydrogen-bonded OH to those from strongly bonded ones. Intensities of the peaks decreased along with the devolatilization and were higher for the doped coals than for the non-doped coals.
