Abstract

Hydrogen formed in oxidative coupling of methane (OCM) over BaCO₃ and MgO catalysts was measured since the data of H₂ selectivity were missing almost in all articles published heretofore. It was found that H₂ selectivity achieved about 18%, when C₂ hydrocarbon's selectivity was maintained at 48%-45% over BaCO₃ catalyst at the feed molar ratio of CH₄/O₂ = 4 in temperature range of 780 °C-820 °C. Under similar conditions, H₂ selectivity was about 14%-16% over MgO catalyst, with C₂ selectivity maintained at 41%-42%. Possible routes for hydrogen formation in OCM reaction were discussed. Effect of addition of alkali metallic ions was also investigated.
