Production of carbon black from oil-based raw materials

The preparation processes of carbon black are mainly divided into two categories: incomplete combustion methods and pyrolysis methods. Specific methods include oil furnace method, thermal cracking method, acetylene method, pit method, gas phase method, deposition method, low-temperature plasma method, and graphitized carbon black method.

Newly produced carbon black requires post-processing steps to optimize performance: converting powdered carbon black into spherical particles through wet or dry granulation to enhance flowability and storage safety, and then utilizing mechanical grinding and other means to precisely control particle size distribution and specific surface area, meeting the differentiated application needs for rubber reinforcement, ink coloring, and plastic modification.

Pyrolysis Recycling of Waste Tires to Produce Carbon Black

Under the dual constraints of resources and the environment, traditional carbon black production models have encountered bottlenecks, while the pyrolysis recycling of waste tires has opened up a new path for green transformation.
Waste tires are first subjected to thorough cleaning, then cut or crushed into suitable particle-sized materials for processing. Through magnetic separation, metal components such as steel wires are effectively removed. The pre-treated materials are dried and preheated to an appropriate temperature before being fed into the pyrolysis reactor, where thermal decomposition occurs in an inert gas atmosphere (such as steam or nitrogen). Depending on the desired characteristics of the carbon black, the pyrolysis process parameters are adjusted accordingly to achieve precise control over product quality and yield.
