近年来,我们通过对各类热解器的性能原理的比较,自行设计和加工了立式、管状、控温石英热解炉.根据美国Varian公司生产的3700型气相色谱仪的特点,将该炉改装在填充柱气化室上,同时自制合理的冷阱收集系统和分流柱接头,并采用高分辨的毛细管色谱柱,经操作条件的选择试验,获得了能较好反映干酪根组成特征的色谱峰形图.其中正构烯、烷烃的分离度达100%.主要组份数据计算采用丙烷标准气外标定量法和归一化法,重复性好,相对平均误差为10%左右.

This paper introduces a new method for the quantitative and qulitative determinations of the pyrolytic product of kerogen,using cold trap collector devices designed and made by ourselves and Varian model 3700 GC.This method is recently worked out with satisfaction and has been proved to be useful in the study of oil-generation.
