【摘要】 在分析中国石油辽化炼油厂0#柴油的烃族组成、蜡碳分布的基础上,研制出一种柴油低温流动性改进剂。实验结果表明,这种柴油低温流动性改进剂能十分有效地提高中国石油辽化炼油厂0#柴油的低温使用性能。并在实验室评价了LDY柴油降凝剂对几种0#柴油的低温流动性能的改进效果。更多还原

【Abstract】 On the basis of analyzing for carbon distributions of n-paraffins and for hydrocarbon compositions of diesels,a new pour point depressant is prepared.According to the results of the cold filter plugging point(CFPP) test,it is found that this kind of pour point depressant is very helpful to improve the low temperature flowing properties of liaohua 0~# diesel.The pour point depressant(PPD) was evaluated in laboratory for 0~# diesels.It was clear that it was superior to some other pour point depressants in adaptability to diesels of some main refineries and oil fields.更多还原
