Abstract

Abstract: he RMG380 marine fuel oil was prepared by vacuum residue, coking wax oil and ethylene tar, the oil-soluble viscosity depressant was synthesized by maleic anhydride, styrene and octadecyl acrylate(MSA). The optimized synthesis conditions are as follows: octadecyl acrylate, styrene and maleic anhydride monomer ratio 5∶1∶3, dosage of initiator 0.6%, synthetic temperature 90 ℃, reaction time 6 h. This synthesized viscosity depressant was evaluated under the concentration of 300 mg/L and shear rate of 2 000 r/min at 50 ℃, the ratio of viscosity reduction of marine fuel oil can reach 66.11%, and meet the ISO8217—2005 RMG380 viscosity requirements of marine fuel oil. Meanwhile, this viscosity depressant was suitable for different marine fuel oil, while viscosity reducing effect gradually weakened with the increase of time.

Key words: Marine fuel oil, Terpolymer, Viscosity depressant, Synthesis, Effect of viscosity reduction

摘要： 以马来酸酐( M) 、苯乙烯( S) 与自制的丙烯酸十八醇醚酯单体( A) 共聚合成了三元共聚物( MS A) 型油
溶性降黏剂, 考察了降黏剂对RMG 3 8 0船舶燃料油的降黏效果。实验结果表明, MS A的最佳合成条件为: 丙烯酸十
八醇醚酯、苯乙烯、马来酸酐物质的量比为5∶1∶3, 反应温度为9 0℃, 引发剂过氧化苯甲酰( B P O) 的质量分数为
0 . 6%, 反应时间为6h。在降黏剂质量浓度为3 0 0m g / L、剪切速率为20 0 0r /m i n时, RMG船舶燃料油的降黏率达
到6 6. 1 1%以上, 满足了I S O 8 2 1 7—2 0 0 5标准中RMG 3 8 0船舶燃料油的黏度要求, 降黏剂对不同的船舶燃料油均具
有较好的降黏效果, 但随着时间的增加降黏效果逐渐减弱。
