How is Carbon Black Manufactured?

Carbon black is typically made through “incomplete combustion” or “thermal decomposition” of hydrocarbon feedstock. The most common feedstock used in carbon black production is natural gas, oil, waste tyre or coal tar. These manufacturing units typically employ processes such as partial combustion or thermal decomposition of hydrocarbons, mainly natural gas or petroleum products.

Manufacturing Process

Carbon black manufacturing is a highly controlled process with various parameters, such as temperature, residence time, and feedstock composition, carefully monitored and adjusted to achieve the desired carbon black properties. Additionally, different manufacturing methods can be used to produce specific types of carbon black, such as furnace black, channel black, or thermal black, each with distinct characteristics and applications. Here is a simplified overview of the carbon black manufacturing process:

Feedstock Preparation: The chosen hydrocarbon feedstock is heated and vaporised to prepare it for carbon black production. This can involve processes such as distillation or cracking.

Carbon Black Formation: The vaporised hydrocarbon feedstock is introduced into a reactor or combustion chamber, undergoing controlled combustion or thermal cracking at high temperatures (around 1,500 to 2,000 degrees Celsius). This process breaks down the hydrocarbon molecules into smaller carbon units.

Particle Formation: As the hydrocarbon molecules break down, the carbon atoms aggregate and form tiny particles. These particles are predominantly carbon, with sizes ranging from 10 to 500 nanometers.

Separation: The carbon black particles are separated from the process gases. This is achieved using a combination of quenching, filtration, and centrifugation processes. The separated carbon black is collected as a powder.

Post-Treatment: The collected carbon black powder may undergo post-treatment processes to modify its properties for specific applications. Post-treatment can involve surface oxidation, pelletisation, or other treatments to enhance dispersibility, improve color, or impart specific characteristics to the carbon black.
