品 名:裂化汽油
拼音:liehuaqiyou
英文名稱：cracked gasoline
說明:由石油重質餾分經裂化而得的汽油。含有烯烴、芳香烴和少量二烯烴。化學穩定性較差。但辛烷值較高，經熱裂化而得的約為55～75，經催化裂化而得的約為80～95。可單獨用作車用汽油，也可與直餾汽油等摻合，或多種裂化汽油相互摻合而成航空汽油等。
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.
