The most important route to produce these unsaturated hydrocarbons is by steam cracking, using principally petroleum gases or naphtha as feedstock.

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。

Naphtha is the main feedstock for steam cracking process, therefore its property directly influences the yields of main cracking products and the operation cycle of cracking furnace.

石脑油作为蒸汽裂解工艺的主要原料，其性质直接影响裂解主要产品收率和裂解炉操作周期。
