輕油又叫做石腦油、白電油。

「由地底下開採出來的石油因為是煉油的原物料,因此也稱之為原油。由原油提煉出來的產品可分為氣體、液體以及固體。原油是黑褐色液體,除燃燒外不具其它實用價值,要經過一連串加工製造提煉過程。

而煉製後的石油可分為輕油及重油。輕油又稱為石腦油,是沸點高於汽油而低於煤油的分餾混合物,經去醇酸處理後可作為汽油及航空燃料油使用。輕油也可經處理後產生高辛烷質的汽油或石油化學原物料,為苯、甲苯、二甲苯的主要來源;另外也可經裂解反應產生乙烯、丙烯、丁烯、戊烷、芳香烴及碳煙;也可經過加氫裂解反應產生汽油及液化石油氣。」(Digitimes

主要用作化肥、乙烯生產和催化重整原料,也可以用於生產溶劑油或作為汽油產品的調和組分。某些石油煉廠還生產少量的特種輕油用作溶劑,清洗液,油漆和清漆稀釋劑,瀝青稀釋劑,橡膠工業溶劑,乾洗,打火機,便攜式野營爐和燈籠燃料的。這些都是輕油進行各種純化過程可以製造的。(wiki
