Abstract:
This study investigates the co-conversion of methane and ethane in a T-shaped reactor over a resistive fechral catalyst heated to 1000°C. The feedstock consisted of two cold gas mixtures injected into the reactor separately: (1) 30 vol % CH4 + 70 vol % N2 (or N2 + O2); and (2) 30 vol % C2H6 + 70 vol % N2 (or N2 + O2). The simultaneous introduction of the methane–nitrogen and ethane–nitrogen mixtures into the reactor was found to enhance the selectivity of methane conversion to C3 hydrocarbons. This finding can be explained by the fact that the main reaction path involves interaction between the surface forms of methane and ethane stabilized in the carbon deposit layer on the surface of the resistive fechral catalyst. The article emphasizes the role of carbon deposits on the catalyst surface in the stabilization of CH3 • radicals. These radicals are predominantly involved in oligomerization and polymerization reactions, including those in the presence of oxygen, due to the preferential occurrence of chain propagation reactions, rather than oxidation, because the major portion of the reaction mixture is at near room temperature.
