丙烯酸酯类聚合物降凝剂研究进展

目前我国开采的石油及其相应的油品中蜡含量高,蜡在低温条件下会结晶析出,严重影响了石油及其油品的良好使用。在众多的降凝剂中,丙烯酸酯类聚合物降凝剂以其优异的性能引起了研究人员的注意。本文对降凝剂作用机理进行了介绍。此外,着重按照丙烯酸酯类聚合物降凝剂的聚合状况进行了综述,主要介绍了丙烯酸酯的不同均聚物、二元共聚物以及三元共聚物、乃至其和不同物质混合时的降凝效果。

Research Progress of Acrylic Ester Polymer Pour Point Depressants

Nowdays, Chinese crude oil and its corresponding petroleum products have high paraffin content; the paraffin can crystallize at the low temperature, which seriously affects the better use of crude oil and petroleum products at low temperatures. Acrylic ester polymer pour point depressant has been well known due to its excellent performance. In this paper, the mechanism of pour point depressants was described. Besides, the development of acrylic ester polymer pour point depressant was introduced. At last, the pour point depression effect of different homopolymer,bipolymer and terpolymer of acrylic ester as well as its mixture with other material was discussed.
