AI Technical Summary
Technical Problem
Existing methods for producing carbon black are limited to liquid carbon-containing feedstocks, and the thermal decomposition of particulate materials at high temperatures is challenging, resulting in low solid yield and undesirable coke and ash content.
Method used
A method for producing carbon black using particulate carbon-containing raw materials in a co-flow reactor with a high-temperature gas flow of at least 800°C, allowing for the direct thermal decomposition of these materials to form carbon black.
Benefits of technology
The method produces carbon black with desired properties such as BET surface area, oil absorption, and transmittance, while eliminating the need for subsequent processing and reducing coke and ash content.
