The preparation processes of white carbon black mainly include gas-phase method, precipitation method, and dissociation method. Although traditional craftsmanship is mature and stable, it often comes with high energy consumption and environmental pollution issues. With the global emphasis on sustainable development, the green transformation of white carbon black preparation technology has become an industry consensus.

The white carbon black produced by gas-phase method has high purity and excellent performance, but the cost is relatively high. To reduce energy consumption, enterprises are exploring the use of more efficient catalysts and reaction conditions to improve raw material utilization. As the main method for large-scale production of white carbon black, the green transformation of precipitation method focuses on optimizing precipitation conditions, reducing wastewater discharge, and recycling waste. By introducing advanced separation and purification technologies, the production process of precipitated white carbon black is more environmentally friendly.

In addition, new preparation technologies such as dissociation are constantly being developed. These technologies utilize renewable energy or biomass raw materials to dissociate white carbon black through chemical or biological methods, which have the advantages of low carbon and environmental protection. In the future, with the continuous advancement of technology and the reduction of costs, green preparation processes will become the mainstream of the white carbon black industry.
