Abstract

We have investigated the influence of an electric field in the form of a gas discharge on the flame pattern, the radiographic parameters of soot particles, and the yield of fullerenes and polycyclic aromatic hydrocarbons. It has been shown that an external electric field permits controlling the processes proceeding in the flame, as well as the soot formation, and even increasing the soot yield under certain conditions. It has been established that the height of the soot packet L c and the interplanar spacing d 002 remain unchanged with increasing voltage, which is confirmed by the absence of graphitization under the action of the electric field. It has been revealed that negative polarity has a stronger effect on the increase in the yield of fullerenes with increasing voltage applied compared to positive polarity.
