About half of the components of domestic diesel fuel are straight-run products. The rest are the products from secondary proccessing, mainly FCC light cycle oil, a great portion of which are not refined or treated. With the domestic crude oil becoming heavier and the development of heavy oil FCC, the quality of diesel is gradually deteriorating. To meet the requirements of transportation, environment and industries, the quality of diesel fuel must be improved. Besides the development of hydrotreating process,nonhydrogen...

About half of the components of domestic diesel fuel are straight-run products. The rest are the products from secondary proccessing, mainly FCC light cycle oil, a great portion of which are not refined or treated. With the domestic crude oil becoming heavier and the development of heavy oil FCC, the quality of diesel is gradually deteriorating. To meet the requirements of transportation, environment and industries, the quality of diesel fuel must be improved. Besides the development of hydrotreating process,nonhydrogen treating and the uses of stability and combustion improving additives should also be emphasized.

我国柴油组分构成中一半为直馏柴油,其余为催化裂化柴油等二次加工产品。有相当多的柴油组分未经任何精制即调入成品柴油。随着我国原油的变重和催化裂化掺炼重油等深加工技术的发展,柴油质量每况愈下。面对工交、环保的新要求,改进柴油质量势在必行,除了开发柴油加氢精制技术外,亦要重视对非加氢精制技术和改善柴油安定性和燃烧性能的添加剂的开发。

The method for determining cetane number by using FT NIR and partial least square (PLS) regression method was studied.Selection of spectral ranges,pretreatment of spectra,factor number used in PLS and composition of training sample set are discussed.As a result of this study,good correlation with the cetane numbers determined by ASTM method (R 2=0 9724) and good repeatability (standard deviation=0 02) were obtained.However,Different calculation models have to be used for high aromatic samples from FCC and ordinary samples.It is suggested that this presented method with its advantages of better repeatability,shorter time of testing,lower cost and smaller sample size,can be used as an alternative for determining cetane unmber of diesel oils.

采用傅立叶变换近红外光谱技术与偏最小二乘方法结合测定柴油的十六烷值。讨论了训练集样本光谱范围的选择、光谱预处理方法及最佳主因子数的选择。近红外光谱技术测定的结果与标准方法测定的结果有良好的相关性(R2=0.9724)。采用不同的校正模型测定了催化裂化柴油馏分、成品柴油等不同类型样品的十六烷值。与标准方法相比,近红外光谱方法具有重现性好、分析速度快、使用样品量少、分析成本低等优点,可以用于柴油十六烷值的常规分析
