Methane oxidative coupling in an undiluted reaction mixture in a reactor-adsorber system with gas recirculation Original Research Article

Results of the oxidative coupling of methane obtained in a reactor-adsorber system with gas recirculation, with a continuous supply on the methane-oxygen reaction mixture without a diluent gas (p(CH4 + O2) = 1 atm, CH4:O2 = 20:1), are described. At total methane conversion equal to 94%, the C2+ hydrocarbon selectivity of the process was 70%, while ethylene contents was 92% in the obtained hydrocarbons.
