摘要随着非常规石油产量和运输量的增加，对轻质原油的检测方法提出了挑战。中红外光谱能反映油品的官能团，吸收信号强，峰明显，具有快速、经济、稳健的特点。然而，以往对石油相关样品的研究和应用，如石油化工在线监测，主要是基于近红外光谱分析。近年来，光谱仪器制造和数据分析方法的快速发展，为中红外光谱快速准确识别海洋溢油提供了更加全面的技术支持。选取了10个原油样品进行红外光谱分析，并与气相色谱火焰离子化检测法进行了比较。利用主成分分析和偏最小二乘回归对红外光谱和GC/FID图谱的特征信息进行提取和分类。在小样本条件下，识别正确率达到100%。结果表明，中红外法与化学计量学相结合，有望实现快速、准确、经济的稠油油种识别。图形摘要
ABSTRACT With the increase of unconventional oil production and transportation, the detection methods of light crude oil have been challenged. Mid-Infrared spectroscopy can reflect the functional group of the oil related samples, which has strong absorption signals with distinguishable peaks featured as a fast, economy, and robust technique. Nevertheless, the previous study and application of oil relevant samples, such as petroleum chemical industry online monitoring, are mainly based on Near-infrared spectroscopy. Recently, the rapid development of the spectral instrument manufacturing and the data analysis methods provides a more comprehensive technical support for the rapid and accurate identification of marine oil spill by Mid-infrared spectroscopy. In this paper, 10 crude oil samples were selected for infrared spectroscopy detection, and the results were analysed and compared with those of gas chromatography flame ionization detection method. The character information of the IR spectra and GC/FID chromatograms were extracted and classified both by principal component analysis and partial least squares regression. Under the condition of small sample size, the recognition accuracy was up to 100%. The results show that the mid-infrared method combined with chemometrics can be expected to achieve rapid, accurate and economical identification of heavy oil species. GRAPHICAL ABSTRACT
