酸催化合成烷基化油的研究进展

Progress in research on catalytic synthesis of alkylated gasoline

综述了分别以硫酸、氢氟酸等无机酸、固体酸和离子液体为催化剂合成烷基化油的最新研究进展,并对这些催化剂的结构和酸性能对烷基化油的组成和性质的影响规律进行了分析和评述。指出离子液体作为绿色催化剂用于烷基化油的合成表现出易与产物分离、催化活性高、烷基化产物中C8组分含量高、辛烷值高等突出优点,是较有应用前景的烷基化油合成用催化剂。

In this paper, the recent progress in the preparation of alkylated gasoline in the presence of catalyst including inorganic acids, solid acids and ionic liquids, is reviewed. The influences of the catalyst structure, acidic property on the composition, properties of alkylated gasoline are commented. The room temperature ionic liquids are new green catalysts for the preparation of alkylated gasline due to their advantages of high activity, high C8＇s content in alkylated products, high RON value and easy separation from products, and are considered one of the most promising catalysts for the preparation of alkylated gasline.
