Patent ID: 8796497

Claim:
A method for the oxidative coupling of methane to a hydrocarbon other than methane comprising: providing a hydrocarbon feedstream comprising methane and a hydrocarbon other than methane; providing an oxidative catalyst within a reactor, the catalyst consisting essentially of: (A) Mg element from 40 to 90 wt. % of the catalyst; (B) La element from 0.01 to 40 wt. % of the catalyst; (C) Sr element from 0.01 to 40 wt. % of the catalyst; and (D) oxygen, wherein oxygen comprises from 10 to 45 wt. % of the catalyst; feeding the hydrocarbon feedstream and an oxygen source to the reactor; carrying out oxidative coupling of the methane to a hydrocarbon other than methane over the oxidative catalyst according to an oxidative coupling condition to produce a coupling hydrocarbon product stream; and recovering product hydrocarbons comprising ethylbenzene and styrene.
