"INTEGRATED PROCESS FOR PRODUCING OLEFINS FORM METHANE-CONTAINING GAS MIXTURES" Abstract Disclosed is an integrated process for producing olefins by starting from methane containing gas mixture, which process essentially comprises the following steps: -- converting methane into higher hydrocarbons by oxidative coupling carried out in the presence of air and/or oxygen; -- dehydrogenating, with the aid of a catalyst, said higher hydrocarbons, with an olefin-rich mixture being obtained; -- removing H2O, CO2, CO and H2 from the resulting olefinic mixture; -- removing from said olefinic mixture any not converted methane, and recycling it upstream from the oxidating coupling; -- separating ethylene form the olefinic mixture; -- separating any not dehydrogenated ethane from the olefinic mixture.
