应用FTIR分峰程序对页岩油中羰基化合物相对含量测定的研究

DETERMINATION OF RELATIVE CONTENT OF CARBONYL COMPOUNDS IN SHALE OIL BY FTIR DECONVOLUTION PROGRAM

页岩油中的羰基化合物分离富集后,用GC-MS定性,在此基础上,对其谱图中的羰基峰,以统计出的参数为初始值进行分峰处理,得到各族组分的相对含量有半定量意义。此方法简单,不但对页岩油中羰基含氧化合物的研究有一定的实际意义,而且可用于其它类似体系的研究。

Carbonyl compounds in shale oil are isolated, concentrated and identified by GCMS. On the basis already achieved, FTIR deconvolution program of carbonyl group peaks in IR spectrogram is carried out with their statistical parameters taken as the original values. The results of relative contents of the different carbonyl compounds such as ketones, acids, aldehydes, esters can be used for semiquantitative assessment. This is a simple method and has practical significance for studying carbonyl compounds in shale oils.
