AI Technical Summary

Technical Problem

In the traditional carbon black production process, there are problems such as coking, many foreign matters, poor dispersion, and low oil absorption value, resulting in limited product quality.

Method used

A multi-line high-quality carbon black production system is adopted, including several groups of acetylene cracking components, coke particle collection components, carbon black separation components and hydrogen-rich circulation components. Through high-pressure cracking and low-pressure transportation processes, high-speed flowing gas is used to reduce the generation of coke and foreign matter, and the dispersion and oil absorption value of carbon black are improved through cyclone separators and dust collectors.

Benefits of technology

It effectively solves the problem of coke and foreign matter in carbon black products, improves the dispersion and oil absorption value of the product, and improves the quality of carbon black.
