A New Grade Carbon Black Produced by Thermal Plasma Process

Abstract

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