Abstract

The invention relates to a nitrogen-containing diesel oil pour point depressant composition as well as preparation and application thereof. The nitrogen-containing diesel oil pour point depressant composition is prepared from the following components in percentage by weight: 10-40% of mono-isopropanol amine, 10 to 40% of cyclohexane; 0-20% of polyethylene glycol; and 40 to 60% of N,N-tetradecyl methacrylamide-tetradecyl methacrylate. The obtained diesel oil pour point depressant composition is added into No.0 diesel oil sold in the market, and the condensation point and the cold filter plugging point of the diesel are reduced by 21-25 DEG C and 9-13 DEG C respectively.

Description

technical field [0001] The invention belongs to the technical field of diesel oil pour point depressant, and relates to a nitrogen-containing diesel oil pour point depressant composition and its preparation and application. Background technique [0002] Diesel has attracted much attention because of its durability, high efficiency, cleanliness, and safe storage. However, the low-temperature fluidity of diesel oil restricts its use performance, so people's demand for low-condensation diesel oil, especially diesel oil with low cold filter point is even more urgent. Compared with other processes, adding a pour point depressant to produce low-point diesel oil can widen the distillation range of diesel oil and save resources; at the same time, it has the characteristics of flexible operation, low cost, quick effect and retention of high cetane number wax components. An effective way to get high-quality diesel. Diesel pour point depressant, also known as low-temperature fluidity...
