摘　　要：对不同基属原油柴油馏分的凝点、倾点、冷滤点及其相关性进行研究。结果表明,各基属原油柴油馏分的凝点与倾点具有比较好的相关性;石蜡基原油柴油馏分的凝点与冷滤点具有一定的相关性,低硫中间基原油柴油馏分的凝点与冷滤点相关性较好,而含硫及高硫中间基原油柴油馏分的凝点与冷滤点相关性较差;石蜡基原油柴油馏分的倾点与冷滤点相关性较差,低硫中间基原油柴油馏分的倾点与冷滤点有一定的相关性,含硫及高硫中间基原油各柴油馏分的倾点与冷滤点相关性差;环烷基原油柴油馏分的凝点与冷滤点、倾点与冷滤点的相关性都比较好。The relationship of solidification point, pour point and cold filter plugging point of straight-run diesel fractions from various types of crude oil were studied. Results showed that good linear relationship between the solidification point and pour point of diesel fractions from various types of crude oil existed. The relationship between solidification point and cold filter plugging point, as well as the relationship between pour point and cold filter plugging point from good to bad were followed the order of sweet-intermediate type〉paraffinic type〉sour and high sulfur intermediate type. However, as to diesel fractions from naphthenic type crude oils the relationship between solidification point and cold filter plugging point,as well as the relationship between pour point and cold filter plugging point were all quite good.
