摘要
考虑清洁柴油升级,硫和芳烃等组分的减少,柴油的润滑性也有所降低的情况,分析了不同典型工艺生产的13个柴油组分样品的润滑性与硫含量、芳烃含量等指标的关系,结果表明:在不含添加剂的情况下,硫含量较高的柴油表现出较好的润滑性;多环芳烃、苊烯、苊类、萘等组分以及密度与柴油组分的润滑性有较好的对应关系,而与茚类、四氢萘、烷基苯、单环芳烃等基本无关。
The lubricity,density,viscosity and aromatics content of diesel fractions produced from different processes were analyzed. The results showed that,in the absence of additives,the diesel fraction with higher sulfur content showed better lubricity;the density was negatively correlated with the wear scar diameter; the kinematic viscosity and the wear scar diameter did not show a good correspondence;the lubricity of diesel fraction was a comprehensive result which was influenced by the polycyclic aromatics content,density and so on,and was not affected by the monocyclic aromatics content.
