摘要

本文详细介绍顶替色谱法进行轻质原油及凝析油的烃族组分分析。将样品加到色谱柱内,用硅胶作固定相,用乙醇顶替被硅胶吸附的烃类,根据折光率大小,确定不同时间内流出烃类的组分。利用烃类混合物折光率的可加性计算各族组分流出体积,从而计算其体积百分含量。其适用范围也可推广到重质原油的轻质部分分析。

Abstract

A displacement method of chromatography for analysis of group composition of light crude oil and condensate was introduced in the paper.The samples were filled into chromatographic columm,silica gel was used as stationary phase,and ethanol was used to replace the hydrocarbon adsorbed by silica gel.Hydrocarbon composition moved out in different time were determined according to their refractive index(RI).Volumes of various group composition were calculated by using addible RI of hydrocarbon mixtute,then their volume percentage was determinded.This method may be applied to analysis of light composition of heavy oil.
