摘　　要：通过大量低温储存试验，筛选出一种具有降低冷滤点和抗蜡沉积的复合降凝剂。在中国石油化工股份公司济南分公司生产的0号轻柴油中加入750～1000μg／g该复合降凝剂，可使0号轻柴油的冷滤点达到-10号轻柴油的标准，并改善了蜡沉积分层的现象。Storage tests of light diesel fuel at low temperature were carried out to observe the cold flow property and wax separation phenomena. A complex flow improver having the function to suppress wax separation was selected from the screening results. When said complex flow improver was added to the 0^# diesel fuel of SINOPEC Jinan Company at a dosage range of 750-1 000 μg/g,the cold filter plugging point of the fuel reached the -10^# diesel fuel specification, and its wax separation phenomena was improved obviously.
