| 摘 要： | 采用可控予聚的方式合成了HG-2成品油减阻剂,聚合物的黏均相对分子质量大于3.0?106。 对柴油中加入50 mg/L HG-2减阻剂进行指标评价及台架试验和行车试验。结果表明：加入50 mg/L的减阻剂，对柴油性质影响不大，能符合GB252-2011普通柴油的要求；作为燃料，对车辆整体性能无明显的影响。在洛郑驻成品油管道进行了现场试验，加剂10 mg/L,柴油增输率可增加30.1%，加剂量8 mg/L,雷诺数为52 411，70 940，78 087时，对应的增输率分别为26.8%，30.2%，38.6%，增输效果较好。

DEVELOPMENT AND APPLICATION OF DRAG REDUCING AGENT HG-2 SYNTHESIZED BY DOUBLE MATERIAL PRE-POLYMERIZATION METHOD |
| |
| Abstract: | Synthesized HG-2 oil drag reducing agent (DRA) by a new controllable pre-polymerization technology was prepared. The polymer average molecular weight is greater than 3.0?106. Performance evaluation, bench test and road test of diesel fuel with 50 mg/L DRA were conducted. Results show that adding 50 mg/L DRA into diesel fuel has no obvious influence on the vehicle performance and the quality can conform to the GB 252-2011 national standard. Field experiment in oil pipeline was conducted. The delivery rate increase of diesel with DRA10 mg/L can be up to 30%. With 8 mg/L DRA, at Reynolds number of 52411, 70940 and 78087, the corresponding delivery rate increase is 26%, 30.2% and 38.6%, respectively. |
