What is carbon black extracted from?

May 24, 2022

We all know that carbon black is mainly used in rubber tires. Of course, carbon black can also be used in other aspects. However, many friends think that carbon black is extracted, but it is not. What material is not extracted from? Carbon black is not extracted from petroleum or anything. It is formed by incomplete combustion. Carbon black mainly refers to the fine particles formed after incomplete combustion of coal, petroleum, biomass fuel, etc. Here is to introduce what carbon black is made of?

What is the chemical formula of carbon black?

The carbon black produced by the current process is not completely pure, and there are still some impurities in it, but the content of carbon black is still very high, which can reach more than 95%. Therefore, the chemical formula of carbon black can be considered as carbon black. is C.

At present, the main function of carbon black is reinforcement, and of course it also has the functions of coloring, electrical conductivity, anti-static and wear resistance.

So can carbon black be extracted from crude oil?

Both petroleum and heavier or unsaturated hydrocarbon-containing natural gas can produce carbon black without complete combustion. The main raw materials of carbon black are ethylene tar, coal tar, anthracene oil, and carbon black oil. Most of the ethylene tar was used in foreign countries and in China in the early days. Later, it was found that ethylene tar has high cost and low output rate, so it is gradually rarely used. In terms of density, the raw material with high price and low price is carbon black oil, but the quality of carbon black oil in China is too uneven. Of course, carbon black can also be produced using natural gas. At present, coal tar is mostly used in domestic production, and the amount of anthracene oil used ranks second. In the past two or three years, the quality of carbon black oil has improved, and the amount of use has also increased year by year. In addition, the utilization rate of ethylene tar in China is low.
