【摘要】 以α－烯烃、丙烯酸酯、马来酸酐为原料，在实验室合成了一种新型柴油流动改进剂——含氮聚酯型柴油降浊剂。评价了它在两家炼油厂柴油中的降浊效果，表明柴油降浊剂可以降低柴油的浊点、冷滤点及凝点。考察了柴油在加剂前后的析蜡情况、热力学性质的变化以及低温结晶状况，提出了柴油降浊剂的作用机理。更多还原

【Abstract】 A nitrogen contained copolymer was synthesized by alpha olefin, acrylate and maleic anhydride, which is used as a new additive to lower the cloud point as well as improve the cold filter plugging point and solidifying point of diesel fuels. Application examples showed that the cloud point, cold filter plugging point and solidifying point of the diesel fuel can be depressed. The wax separated out, changes of thermaldynamic properties and the low temperature crystallization status before and after adding the additive in diesel fuel were investigated, and a mechanism of depression was proposed.更多还原
