Oxidative coupling of methane is considered to be one of the direct routes in natural gas conversion into more
added value hydrocarbons. In this work, an integrated process, comprising OCM and dehydrogenation of ethane, for
improving the C2H4 yield is introduced. The reactions are performed in a vertical quartz reactor having two reaction
parts which operates at ambient pressure. The best results are obtained when OCM reactions take place on Mn-
Na2WO4/SiO2 catalyst located in the upper reaction part followed by noncatalytical reactions performed in the second
reaction part at CH4/O2=7/1 and 800°C. The operation led to a maximum C2H4 selectivity and ethylene yield of 37.9%
and 16.0% respectively.
