Problems solved by technology

So far, the combination of diesel turbidity reducer and diesel low temperature fluidity improver and the consumption of additives in diesel have not been reported
[0008](3) Generally, the flash point of diesel pour point depressant is around 30°C, which belongs to the first-class dangerous goods. According to the actual situation that most users do not have the storage capacity for dangerous goods

Abstract

The present invention discloses one kind of diesel oil pour point reducer, which consists of alpha-olefin 5-15 wt%, acrylate 15-30 wt%, maleic anhydride 20-45 wt%, fatty amine 10-25 wt%, and alkyl naphthalene 20-50 wt%. The diesel oil pour point reducer is used mainly for adding into 0# diesel oil so as to improve it into -10# diesel oil. Practical application shows that it has the excellent performances of high storage safety with flash point up to 70 deg.c or so and high pour point reducing effect.

Description

technical field [0001] The invention relates to a pour point depressant, in particular to a pour point depressant for diesel. Background technique [0002] In industries such as energy and transportation, diesel plays a very important role. Especially No. 0 diesel oil accounts for more than 70% of the total amount of diesel oil. A prominent problem in the use of No. 0 diesel oil is poor low temperature fluidity. Especially in the south of the Yangtze River, the use of diesel oil in winter due to the high cloud point causes insufficient fuel supply to the engine, which directly affects the normal operation of the engine. In recent years, the prices of gasoline and diesel have continued to rise. The use of -10 diesel in winter not only increases fuel costs, but also often suffers from resource constraints. [0003] Domestic additives used to improve the low-temperature performance of diesel have been widely used in -20 and -35 diesel. But for No. 0 diesel oil, the addition...
