黄姜皂素残渣PY-GC/MS热裂解

PY-GC/MS investigation for cracking of solid waste from turmeric industry

应用裂解-气相色谱质谱(PY-GC/MS)分析技术,对黄姜皂素生产固体废弃物在400℃/S、800℃/S、闪速条件下升温至1000℃时的裂解产物的主要组分及相对含量进行了分析。研究结果表明:随着升温速率的提高,总离子流图(TIC)上各特征裂解产物的出峰时间趋于分散,且不同速率下裂解产物及含量存在显著差异。黄姜皂素残渣热裂解产物主要是芳香烃及其衍生物、烷烃及其衍生物,其含量分别占总质量的25.139%～47.542%及5.367%～16.307%。本研究为黄姜皂素残渣的有效利用和黄姜皂素绿色生产工艺的开发奠定了一定基础。

PY-GC/MS was applied to analyze the components and contents in the cracking of turmeric industry solid waste.The cracking was conducted at heating rates of 400 ℃/S or 800 ℃/S and flash to 1000 ℃.Results showed that characteristic productions went dispersive on the TIC chart with the increase in heating rate,both components and contents of the productions were quite different under different heating rates.The major cracking components were found as aromatics and their derivatives （25.139%—47.542%）,and as alkanes and their derivatives （5.367%—16.307%）.
