摘 要： 柴油是我国主要能源之一，但柴油长期储存颜变深、渣质增多、气味变臭，严重影响了柴油的质量和使用性能。本文主要对劣质柴油进行研究，分析影响其性的因素。选择酸洗结合甲醇-氨水复合溶剂萃取法对其进行精制。达到了较好的脱、脱渣、脱臭效果。选择的酸为硫酸，酸油比0.2：50（v：v），酸洗后再用甲醇氨水复合溶液进行溶剂萃取。氨水浓度为15%，甲醇与氨水体积比为5：1，萃取温度30摄氏度，萃取后柴油号能降到6～7号。 激光投影键盘 关 键 词：劣质柴油；颜；渣质；气味

Abstract： Diesel oil is one of the major energy in our country， but long-term storage hbv疫苗
陶瓷发簪of diesel oil can make the color darker， the slag increase， which will affect the quality of the diesel. In this paper， the inferior diesel was studied， and factors to affect its stability were analyzed. The method of pickling and alcohol ammonia composite solution extraction was used to refine the inferior diesel. Good decoloring， deslagging and deodorization effect was achieved. The pickling process used H2SO4，the acid-oil ratio was 0.2：50（v：v）. After the pickling， methanol-ammonia complex solution was used to carry out solvent extraction， the ammonia concentration was 15%， the volume ratio of methanol to ammonia was 5：1（v：v）， and the extraction temperature was 30 ℃. After the extracting， the diesel color number was reduced to 6～7.
