【摘要】 提出一种分析原油非烃结构和含量的方法。用直观推导式演进特征投影法分辨有关二维数据以获得非烃的纯色谱和纯质谱, 再将所获质谱在标准质谱库中检索, 并结合色谱保留指数分析等来进行单个非烃化合物结构鉴定; 利用实验数据,根据分辨获得的纯色谱峰面积所建立的规一化模型, 进行非烃化合物定量分析。用本法确定了一原油样品中 168个含氮化合物和该油样一个馏分中 60个其它非烃化合物的结构和含量。本方法具有系统分析原油非烃结构和含量的通用性;标准化合物加标回收实验表明, 其准确度很好。更多还原

【Abstract】 A new method was presented for the structure identification and content analysis of non hydrocarbons in crude oils. The structural identification of the specific non hydrocarbon compounds was carried out by resolution of the two dimension data using heuristic evolving latent projection method in order to obtain the deconvoluted chromatograms and mass spectra from the non hydrocarbons, match of the deconvoluted mass spectra against a database of electron impact spectra and chromatogram retention index analyses, etc; the quantitative analysis of the non hydrocarbon compounds was carried out by use of experimental data and normalization model based on the peak areas of the deconvoluted chromatograms. The structures and contents of 168 nitrogen containing compounds in one crude oil sample and 60 other non hydrocarbon compounds in one of non hydrocarbon fractions of this oil sample were determined by this method. The method is universally suitable for analyzing structures and contents of the non hydrocarbon compounds in different crude oils, and the addition recovery examination of standard compounds shows that the analytical veracity is satisfactory.更多还原
