Is petroleum a chemical product?

Petroleum is not a chemical product, it is the raw material of chemical products. Petroleum, also known as crude oil, is a viscous dark brown liquid. There are oil reserves in some parts of the upper crust. The main components are mixtures of alkanes, cycloalkanes and aromatic hydrocarbons. Petroleum is mainly used as fuel oil and gasoline, and it is also the raw material of many chemical products such as solutions, fertilizers, pesticides and plastics.

Petroleum is a viscous dark brown liquid. There are oil reserves in some parts of the upper crust. The main components are mixtures of alkanes, cycloalkanes and aromatic hydrocarbons. There are two theories about the mechanism of petroleum formation, namely, biological deposition and petrochemical formation. The former is widely accepted that oil is formed by the long evolution of organisms in ancient oceans or lakes, which belongs to biological deposition and cannot be regenerated.

The latter thinks that oil is generated by carbon in the earth's crust, which has nothing to do with living things and is renewable. Petroleum is mainly used as fuel oil and gasoline, and it is also the raw material of many chemical products such as solutions, fertilizers, pesticides and plastics. The Chinese name "Petroleum" was first named by Shen Kuo, a great scientist in the Northern Song Dynasty.

Oil content:

Petrochemical products are obtained by further chemical processing of crude oil provided in the refining process. The first step in the production of petrochemical products is to crack raw oil and gas (such as propane, gasoline, diesel oil, etc.). ) to produce basic chemical raw materials represented by ethylene, propylene, butadiene, benzene, toluene and xylene.

The second step is to produce all kinds of organic chemical raw materials (about 200 kinds) and synthetic materials (synthetic resin, synthetic fiber and synthetic rubber) from basic chemical raw materials.
