Abstract: A method of autothermal oxidative coupling of methane (OCM) utilizes introducing a methane-containing feedstock and an oxygen-gas-containing feedstock into a reactor (10) as a flowing mixture (18) with a space time of 500 ms or less. The reactor (10) contains a catalyst bed (20) of an OCM catalyst that contacts the flowing mixture and wherein the catalyst bed (20) has a heat Peclet number (Peh) of from 5 or less, a mass Peclet number (Pem) of from 5 or more, and a transverse Peclet number (P) of from 1 or less while contacting the flowing mixture. The methane and oxygen of the feedstocks are allowed to react within the reactor (10) to form methane oxidative coupling reaction products. A reactor (10) for carrying out the OCM reaction is also disclosed.

Abstract: Methods of performing a startup of an oxidative coupling of methane reaction to produce C2+ hydrocarbons are described. The methods can include incrementally varying startup parameters of the oxidative methane reactor and using the feed gas as a coolant such that high C2+ hydrocarbon selectivity is achieved.

Abstract: Disclosed is a method for production of ethylene by an oxidative coupling of methane process in the presence of a catalytic material. Heat generated from the oxidative coupling of methane can be transferred to an inert material in an amount sufficient to reduce thermal deactivation of the catalytic material.
