- 柴油冷滤性能改进剂是柴油生产中的一种重要的燃料添加剂。它可以显著改变柴油的低温流动性能,进而可拓宽柴油馏程,提高柴油产率,提高柴油品质,对增加炼油厂的经济效益具有重要意义。 国内从60 年代开始柴油降凝剂的研究,但在早期开发工作中存在着一些问题:一是衡量柴油性能的指标以往仅是凝点一项,二是国内开发品种主要仍以仿制为主,存在着对柴油依赖性强,感受性差的问题。其中最主要而且普遍存在的就是降低凝点而不降低冷滤点的问题。 大庆柴油的碳数分布主要集中在C14～C18,峰值基本相近,碳数分布相对集中。并成明显的正态分布曲线。而且C20～C26 的高碳数的蜡含量高,需要控制好改进剂组分的分子量及其分布,使之能与高碳蜡和低碳蜡相匹配产生吸附与共晶,抑制蜡晶的成长变大,才能降低冷滤点,

The diesel oil cold filter plugging point(CFPP) improver agent is important in the diesel oil production. It may remarkably change the diesel oil the low temperature flow properties, then may open up the diesel oil distillation, enhances the diesel oil production rate, enhances the diesel oil quality, to increases the refinery the economic efficiency. It is from the 60's that starts the diesel oil pour point depressant research in domestic, but there still is some problems in the early development work:.First is the diesel performance target formerly was a pour point item, Second was the domestic development variety mainly still by imitates primarily. It dependent on the diesel oil. The most mainly question is only reducing the pour point but not reducing CFPP. Daqing diesel carbon numbers distribution mainly concentrates in C14 ~ C18. the peak value basically is close, carbon numbers distribution relative centralism. Combines to make or become the obvious normal distribution curve. Moreover C20 ~ C26 high carbon numbers wax contents are high. It needs to control the good improvement medicinal preparation component the molecular weight and it’s distribution. It has the adsorption with high-carbon and the low-carbon wax phase match and eutectic. The suppression wax crystal growth can reduce CFPP.

The diesel oil cold filter plugging point (CFPP) improver agent is an important fuel additive in diesel oil production. It may remarkably change the flow properties of diesel oil at low temperature, and thus raise the distillation range of diesel oil, increase the diesel oil output, improve the diesel oil quality, which has significant meaning in improving economic efficiency of the refinery. It was from the 1960's that China started research on the diesel oil pour point depressant, but there are still some problems in the early development work, Firstly, the evaluation index of diesel performance was previously only the pour point, Secondly, the domestic development was mainly focusing on cloning and dependent on the diesel oil. The major&general problem was how to reduce the pour point without reducing CFPP. Carbon distribution of Daqing diesel oil is mainly concentrated in C14 ~ C18, the peak values of which are basically close to each other, that is to say, carbon distribution is relatively centralized. It presents obvious normal distribution curve. Moreover, the wax contents of C20 ~ C26 with high carbon numbers are high And the molecular weight of improver and its distribution should be controlled, so as to match with the high-carbon and the low-carbon wax to facilitate adsorption and co-crystallization, to suppress the growing of wax crystal and thus to reduce CFPP.
