“…Based on this argument, Wang et al [11] further claimed that low operating pressures would promote the formation of fullerenes because a higher axial velocity obtained by the fast expansion of plasma gas can increase the temperature gradients experienced by fullerenes precursors. But this conclusion disagrees with the experimental observations reported by Yoshie and Cota-Sanchez [6,15].…”

“…Recently, it has been demonstrated that large-scale production of fullerenes is feasible by evaporating carbon-containing materials in RF induction thermal plasma reactors [11][12][13][14][15][16][17][18][19] (see Fig. 1).…”

“…Thus, there have been systematic efforts to study the effect of operating parameters on the final yield of fullerenes in the RF plasma process. Cota-Sanchez et al [15] extensively explored a fullerene synthesis process by an RF plasma jet (2)(3)(4)(5) to investigate the effect of the operating parameters on the fullerene formation, e.g., operating pressure, plate power, and carbon feed rate. Todorovic-Markovic et al reported the dependence of the fullerene yield on the properties of the graphite powder, e.g., mean aggregate size and thermal conductivity, as well as on the helium content in the plasma gas [17][18][19].…”

A mathematical model has been developed on the continuous synthesis of fullerenes by direct evaporation of carbon-containing materials using induction thermal plasma technology. The main purpose of this study is to numerically investigate the effect of plasma gas composition and operating pressure on the fullerene formation. The simulation results confirmed that Ar-He mixture plasma is more efficient than argon plasma in terms of the particle evaporation, generation of fullerene precursors, fullerene growth and their annealing, and that low pressure operation would decrease the overall yield rate of fullerenes by enhancing the radial diffusion of carbon vapors towards the reactor walls. Thus an operating condition of relatively high helium content in the plasma gas and elevated gas pressure seems much more desirable for achieving a high yield rate of fullerenes. This conclusion is in line with the experimental evidences reported previously.

The radio frequency (RF) inductively coupled plasma technique is a new and promising synthesis method of single-walled carbon nanotubes (SWCNTs) at large scales, for industrial and commercial applications. In this method, a mixture of carbon black and metal catalysts is directly vaporized by the RF plasma. Subsequently, inside the reactor chamber and under a controlled temperature gradient, carbon-metal clusters are formed and become the potential sites for nucleation and growth of SWCNTs. In this process, the local plasma properties and the thermo-fluid field in the system affect the yield rate of SWCNTs, and therefore it is important to find an appropriate operating condition, which maximizes the yield rate. Numerical modeling in conjunction with experimental studies can help investigate the contribution of the thermo-fluid field and process parameters to the formation of catalyst nanoparticles and carbon nanotubes in the induction thermal plasma system. The goal of this research is to carry numerical study of SWCNT growth in a RF induction thermal plasma system with a suitable chemistry model. This model is employed to investigate the influence of the thermo-fluid field and gas-phase reactions on carbon nanotube growth and to predict the SWCNT yield rate as a function of operating conditions.
