石油这个名字,知道的人是很多的,假若一提到石油是怎样生成的,那里来的,也许知道的人就没有那样多了。现在我想简单的介绍一点关于这方面的知识。石油是什么?简单的说,石油是一种极复杂的碳氢化合物,是一种天然产生的可燃性液体,它没有固定的成分。我们日常所说的煤油、汽油、柴油等,都是石油中的一部份。刚从地下取出来的石油叫做原油,是一种黑绿色的,褐色的或近于白色的液体,经过蒸馏以后,可以依次分出汽油、煤油、轻油、重油、滑润油以及残渣来。这些东西各有各的不同用途.汽油、轻油、重油用于发动,煤油用于燃点,残渣中的沥青可以铺
There are many people who know the name of oil. If one mentions how oil was generated, people who come there may not have known as much. Now I want to briefly introduce a bit of knowledge about this. What is oil? Simply put, oil is a very complex hydrocarbon, a naturally occurring flammable liquid that has no fixed ingredients. The kerosene, gasoline, and diesel we all talk about in the daytime are all part of the oil. The oil that has just been taken out of the ground is called crude oil. It is a dark green, brown or near-white liquid. After distillation, gasoline, kerosene, light oil, heavy oil, lubricating oil and residue can be separated. These things have their different uses. Gasoline, light oil and heavy oil are used for launching. Kerosene is used for burning. The asphalt in the residue can be paved.
