Etude de la formation de nanoparticules de carbone au cours de la décomposition thermique d'hydrocarbures : application à la coproduction de noir de carbone et d'hydrogène par craquage thermique du méthane par voie plasma

Abstract : This thesis takes part of the development of a direct decarbonation process of methane by plasma to produce both carbon black and hydrogen. This process is particularly interesting in an electrical mix context with low carbon emission. It proffers a solution to reduce drastically CO2 emissions rejected by the current carbon black and hydrogen ways of production, which are ones of the most polluting industrial processes.This study aims to develop reliable and robust numerical methods for a better understanding and a greater control of the morphologic features of the carbon black generated. These features play a key role in the quality and applications of the carbon black produced. This research retraces the evolution of the carbon structure from the molecules of the fuel to the formation of nanoparticles and solid microstructures. It tackles different phenomenon such as: nucleation, chemical growth, coagulation, maturity and aggregation.Numerical tools and methods were developed thereby and enable to simulate carbon particle formation. They were successfully implemented in a commercial CFD software. Eventually numerical simulation of the plasma process were performed, integrating heat transfers and turbulence.
