In both the presence and absence of limited 02, ethane conversion increases markedly because of the presence Of CO2, indicating its beneficial effect on the ethane to ethylene cracking. The increased ethane conversion is, however, not due to the oxidation of ethane to ethylene by CO2; the formation of carbon monoxide in the presence Of CO2 is found to be very small. It is most probably due to the activation of ethane in the presence Of CO2.</p>10aethane10aethane cracking in presence Of CO210aethane cracking in presence of CO2 and limited O-210aEthylene10athermal cracking of ethane1 aChoudhary, Vasant, R.1 aMondal, Kartick, C.1 aMulla, Shafeek, Abdul Rash  uhttps://library.ncl.res.in/content/non-catalytic-pyrolysis-ethane-ethylene-presence-co2-or-without-limited-o-2-0
