摘要：

Influence of the initial methane-oxygen mixture dilution with steam on the parameters of the oxidative coupling of methane is studied. Catalytic tests of Pb-Mg, Sm-Mg, Bi-Ca, Zr-Mg and Na-Ca oxide systems are carried out with steam content 50-70% at 700-850-degrees-C and P(CH4)/P(O2)= 1,5-4,9. It is shown that the addition of steam gives increase of ethylene yield up to 12-16 mol%. The role of steam is investigated.
