Dynamics of methane pyrolysis on the MgO/SiC catalyst was examined at different temperatures of the resistive catalyst. The conversion of methane on the MgO/SiC catalyst at 1200°C passes through a minimum (29%) by 60th minute, with the selectivity with respect to acetylene steadily increasing during the whole experiment. The scanning microscopy with EDAX analysis demonstrated that the full carbonization of the MgO/ SiC sample at 1200°C also occurs after 60 min of the experiment. It was found that a carbon coating of layered structure is formed on the catalyst surface in the course of the experiment, with C2 hydrocarbons still present among the pyrolysis products. It was shown that carbon deposits formed on the surface of the MgO/SiC catalyst are catalytically active in the process of acetylene formation.
