在石油化学工业中所用的许多原料是不饱和烃类，如乙烯、丙烯、丁烯和丁二烯。
Many of the raw materials used in the petrochemical industry are unsaturated hydrocarbons, such as ethylene, propylene, butene and butadiene.
生产这种不饱和烃类最重要的路线是靠蒸汽裂解，主要以石油气体和石脑油作原料。
The most important route to produce these unsaturated hydrocarbons is by steam cracking, using principally petroleum gases or naphtha as feedstock.
化合物的类型主要为饱和脂肪酸酯(33.834%)和烃类化合物(22.031%)。
The main components were saturated fatty acid esters (33.834%) and hydrocarbon (22.031%).
由于石油的主要成分包括饱和烃、芳香烃类化合物、沥青质、树脂类等，这些物质难以降解，并且对水生生物有毒杀作用。
The main components of oil are saturated hydrocarbons, aromatic compounds, asphaltenes, resins, and so on. It is difficult to degrade these substances which are bad for aquatic life.
