Examples
Embodiment 1
[0031] A diesel oil pour point depressant composition, calculated by mass percentage, each component and its content are as follows:
[0032]
[0033] Wherein, the pour point depressant used is EVA pour point depressant.
[0034] The above raw materials are directly mixed according to the mass ratio to obtain the diesel pour point depressant composition.
[0035] The composition is added to Songjiang 0# diesel oil according to the mass of 0.15%, and ultrasonically dispersed at 40°C for 30 minutes. After testing, the condensation point and cold filter point of the commercially available 0# diesel oil containing the diesel pour point depressant composition obtained in the above examples were lowered by 10°C and 5°C, respectively.
Embodiment 2
[0037] A diesel oil pour point depressant composition, calculated by mass percentage, each component and its content are as follows:
[0038]
[0039] Wherein, the pour point depressant used is EVA pour point depressant.
[0040] The above raw materials are directly mixed according to the mass ratio to obtain the diesel pour point depressant composition.
[0041] The composition is added to Songjiang 0# diesel oil according to the mass of 0.15%, and ultrasonically dispersed at 40°C for 30 minutes. After testing, the condensation point and cold filter point of the commercially available 0# diesel oil containing the diesel pour point depressant composition obtained in the above examples were lowered by 13°C and 11°C, respectively.
Embodiment 3
[0043] A diesel oil pour point depressant composition, calculated by mass percentage, each component and its content are as follows:
[0044]
[0045] Wherein, the pour point depressant used is EVA pour point depressant.
[0046] The above raw materials are directly mixed according to the mass ratio to obtain the diesel pour point depressant composition.
[0047] The composition is added to Songjiang 0# diesel oil according to the mass of 0.15%, and ultrasonically dispersed at 40°C for 30 minutes. The condensation point and cold filter point of the commercially available 0# diesel oil containing the diesel pour point depressant composition obtained in the above examples were lowered by 12°C and 3°C, respectively.
