摘要:
 采用纤维素和添加KCl 的纤维素制焦,通过原位漫反射傅里叶变换光谱(DRIFTS)对焦表面官能团特别
是羰基官能团进行分析,研究纤维素焦在等加热速率和恒温条件下的低温氧化特性及K 的影响.结果表明,随
着温度和时间的增加,氧化作用表现为生成更多的羰基官能团(1,900~1,500,cm-1 之间).K 对焦表面官能团的演
变有明显影响.等加热速率下羰基官能团强度增加明显,含K 焦的每个含氧官能团增加都比无K 焦的少;等温
分析表明,在120,℃和180,℃下恒温氧化时,含K 焦形成的羰基官能团也比无K 焦的少.
Abstract:
 Cellulose and KCl doped cellulose were pyrolyzed to generate chars.In-situ diffuse reflectance infrared
Fourier transform spectroscopy(DRIFTS)was employed to analyze the functional groups,especially carbonyl
groups,on char surface so as to investigate low temperature oxidation characteristics and the impact of K during
the heating of chars in air at constant heating rates and under isothermal conditions.The results showed that with
the increase of temperature and time,oxidation is represented by more carbonyl functional groups(1,900—
1,500,cm-1)formed.The presence of K has a significant impact on the evolution of functional groups.Under constant
heating rate,the increase in carbonyl intensity of K doped char is obviously weaker than that of cellulose
char.The analysis of isothermal oxidation showed that fewer carbonyl groups were formed on K doped char than
those on cellulose char during the oxidation at 120,℃ and 180,℃.
