Petroleum can be extracted into solvent oil, aviation kerosene, aviation gasoline, ordinary gasoline, diesel oil, lubricating oil, gear oil, heavy oil, paraffin and so on.
- In industry, petroleum gas, gasoline , kerosene and diesel can be extracted by atmospheric fractionation ;
- In the industry, through vacuum fractionation , lubricating oil , paraffin , alkane pentane with relatively large molecular weight, and aromatic hydrocarbons such as benzene and toluene can be obtained;
- In industry, light oil and gaseous olefins, such as ethylene, propylene, butene, butadiene, can be obtained through the catalysis and cracking of petroleum.
what can be extracted from oil
Petroleum is a viscous dark brown liquid known as the “blood of industry” and is one of the main objects of geological exploration.
Petroleum is stored in the upper part of the earth’s crust and is mainly composed of a mixture of various alkanes, naphthenes and aromatics. There are two theories about the mechanism of petroleum formation: biological sedimentation into oil and petrochemical into oil. The former is widely accepted. It is believed that oil was formed by long-term evolution of organisms in ancient oceans or lakes. It belongs to biological deposition into oil and is not renewable; the latter believes that oil is generated from carbon in the earth’s crust, and carbon has nothing to do with biology and is renewable. Petroleum is mainly used as fuel and gasoline. It is also the raw material for many chemical industry products such as solutions, fertilizers, pesticides and plastics.
