摘　　要：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。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.
