裂化汽油（cracked gasoline），是石油重质馏分经裂化而得的汽油。

品 名:裂化汽油

拼音:liehuaqiyou

英文名称：cracked gasoline

说明:由石油重质馏分经裂化而得的汽油。含有烯烃、芳香烃和少量二烯烃。化学稳定性较差。但辛烷值较高，经热裂化而得的约为55～75，经催化裂化而得的约为80～95。可单独用作车用汽油，也可与直馏汽油等掺合，或多种裂化汽油相互掺合而成航空汽油等。

nature : from heavy oil fractions derived by cracking gasoline. Contain olefins, aromatics and olefins small two. Chemical instability. But the higher octane number, derived by thermal cracking of about 55 ~ 75, the FCC proceeds of about 80 ~ 95. Individually for motor gasoline, but also with straight-run gasoline and other admixtures, or more of a mixture of cracking gasoline from aviation gasoline.
