烷基化油性质特点及企业标准分析

对不同工艺生产的19种烷基化油的质量进行跟踪和分析，结果表明烷基化油具有高辛烷值、零芳烃、低烯烃、低氧含量的特点。探讨了烷基化油的辛烷值、初馏点、蒸气压、硫含量、烯烃含量等指标对调合汽油性能的影响，建议生产和应用企业应对其重点关注。选择典型烷基化油调合国Ⅵ标准车用汽油并验证其性能，制定了烷基化油一级企业标准《异辛烷组分》（Q/SH PRD 0753-2019），使烷基化油的采购、生产和销售有标可依，确保烷基化油质量满足国Ⅵ标准汽油调合要求。

DEVELOPMENT OF LOW DOSAGE ADDITIVE PACKAGE FOR SJ GRADE GASOLINE ENGINE OIL

A low dosage additive package for SJ grade gasoline engine oil was developed by the Research Institute of Petroleum Processing using all domestic products. By optimizing the formulation, a SJ 5W-30 grade gasoline engine oil was prepared by adding 7. 8% of the additive package. Bench simulation tests and the sequence IID, IIIE, VE and CRC L-38 engine tests were performed. The test results showed that the qualities of said formulated engine oil met the specifications of API SJ grade gasoline engine oil.
