非金属汽油辛烷值改进剂工业应用分析

针对FCC汽油降烯烃后辛烷值低影响企业高辛烷值汽油调和的问题,室内评价了不同FCC汽油馏分对WK-602型辛烷值改进剂的感受性及与其它调和组分的相互作用。结果表明WK-602可有效提高汽油辛烷值,基础汽油的辛烷值愈低作用效果愈明显,添加量每增加0.5%,RON值可提高0.7~1个单位,与其它高辛烷值组分/添加剂的互溶性好,无消极作用;工业放大应用显示WK-602与高辛烷值组分/添加剂混合分散均匀,调和生产的97#车用汽油指标满足质量标准要求。应用WK-602辛烷值改进剂调和生产93#、97#汽油产品的经济效益良好。

Analysis on Industrial Application of Nonmetallic Gasoline Octane Number Improver

Focusing on the dilemma that high octane number gasoline blending was interfered owing to olefin reduction of FCC gasoline resulted in low octane number, the sensitivity of WK-602 octane number improver for various FCC gasoline fraction and interaction with other blending components were executed for the sake of laboratory evaluation. The experimental results show that WK-602 can effectively promote the gasoline octane number. The lower the octane number of fundamental gasoline, the more prominent the impact. RON can be enhanced proximately by 0.7-1 unit per increasing 0.5% additive dosage. Furthermore, such octane number improver has very favorable solubility with else high octane number components or additive without any negative effect. Industrial scale application indicates that WK-602 can homogeneously disperse when mixing with high octane number components or additives and obtained 97# motor gasoline can completely satisfy quality standards. Using WK-602 octane number improver to blend and produce 93 # and 97 # gasoline is very economical.
