Abstract:
1. A method for the production of micro-domain graphitic materials by decomposition of a hydrocarbon fuel in a plasma reactor comprising a decomposition chamber connected to a plasma generator, wherein the plasma reactor is fed with H 2 as the plasma forming gas, wherein the hydrocarbon fuel is decomposed in a two-step process wherein the hydrocarbons are subjected to a first decomposition step, including the steps of feeding the hydrocarbon fuel into the decomposition chamber in the vicinity of the plasma arc zone and mixing the hydrocarbon fuel with the plasma gas, and wherein the process parameters are adjusted in such a manner that the hydrocarbon fuel does not reach pyrolysis temperature and is only partially decomposed to form polycyclic aromatic hydrocarbons, and the step of mixing the hydrocarbon fuel in the form of polycyclic aromatic hydrocarbons, after the first decomposition step, with the plasma gas and reintroducing the polycyclic aromatic hydrocarbons as a part of the plasma gas into the plasma arc zone in the decomposition chamber and subjecting the polycyclic aromatic hydrocarbons to a second decomposition step, wherein the process parameters are adjusted in such a manner that the heat in the plasma arc zone causes the polycyclic aromatic hydrocarbons to be fully converted into micro-domain graphitic materials.
