A New Grade Carbon Black Produced by Thermal Plasma Process

摘要

This paper presents a new route about producing carbon black, by which the naturalgas cracking is carried out in the absence of oxygen thanks to an electric energy supply externallygiven by a plasma jet. The carbon black produced by this process has a narrow size distributionand a small average diameter of 38 nm as well as a highly branched aggregate. The higher DBPvalue of 1.40 ml/g shows it should be a high structure carbon black. The FTIR spectra shows thatthere are lots of aromatic c-c bonds and a large amount of nitrogen-containing functional groupson the carbon blacks surface, such as -NH, -CN as well as -CH, -OH, -COOH groups.
