What's the difference between petrochemical and petroleum?

In daily life, you must have heard of petroleum, and some of your friends are still studying in a petroleum university. When it comes to oil, people will think it is a precious non-renewable resource. In addition, I will think of another one, that is, petrochemical. There is only one word difference between petrochemical and petroleum, but what is the specific difference? Let's take a look with Bian Xiao!

What's the difference between petrochemical and petroleum?

1, which is substantially different.

Petroleum is one of the main targets of geological exploration. It is a viscous dark brown liquid, which is called "industrial blood". There are oil reserves in some parts of the upper crust. Petrochemical refers to petrochemical industry, which generally refers to the chemical industry with oil and natural gas as raw materials.

2, the scope of application is different

Petroleum is mainly used as fuel oil and gasoline, and it is also the raw material of many chemical industrial products, such as solutions, fertilizers, pesticides and plastics. Petrochemical has a wide range of applications and many products.

Crude oil is cracked, reformed and separated to provide basic raw materials such as ethylene, propylene, butene, butadiene, benzene, toluene, xylene and naphthalene. From these basic raw materials, various basic organic raw materials can be prepared, such as methanol, formaldehyde, ethanol, acetaldehyde, acetic acid, isopropanol, acetone, phenol and so on.

3. Different ingredients and raw materials

The main components of petroleum are mixtures of alkanes, cycloalkanes and aromatic hydrocarbons. The raw materials of petrochemical components are alkynes, olefins, aromatic hydrocarbons and synthetic gas, from which various important organic chemical products and synthetic materials, natural gas chemical industry, can be made.
