Comparative study on catalytic and non catalytic dehydrogenation of ethane to ethylene over MN/Na2WO4/SiO2 by oxygen and CO2 as an oxidant

investigation on the catalytic and non catalytic oxidative dehydrogenation of ethane (ODE) to ethylene by carbon dioxide or oxygen as an oxidant have been carried out at 800oC. The reactions are performed in a vertical quartz reactor which operates at ambient pressure. For the catalytic experiments MN/Na2WO4/SiO2 was used as a catalyst which is fabricated by the dry impregnation method and calcined in air at 850oC for 8 h. The non-catalytic ODE reaction by CO2 and O2 led to ethylene selectivity of 97% and 88% respectively.
