Comparison between new carbon nanostructures produced by plasma with industrial carbon black grades

Among the large number of processes parameters in Carbon Black (CB) manufacturing, temperature is certainly one of the most important. Whatever the process and the feedstock are, all the processes have in common a limited temperature, as a result of the feedstock energy contain. In the first part of this paper, we establish relationships between temperature and texture of the blacks, based on the analysis of different CB grades. In a second step, we try to give explanations of some possible relationships between processes parameters and applicative properties of the blacks. Then, we present a new plasma technology for CB production from hydrocarbons cracking. The original technology will allow to investigate, at a pilot scale, a wide range of temperatures. Preliminary results obtained with the pilot are presented.
