Abstract:
A process for the oxidative coupling of methane to one or more C2+ hydrocarbons which includes subjecting a gas stream comprising methane, ethylene, optionally ethane and optionally nitrogen, resulting from subjecting methane and oxygen or air to methane oxidative coupling conditions, to two consecutive sorption steps which comprise contacting said gas stream comprising methane, ethylene, optionally ethane and optionally nitrogen with a selective sorption agent, resulting in sorption of part of said gas stream, comprising ethylene and optionally ethane, by the sorption agent and in a gas stream comprising the remainder of said gas stream, comprising methane, optionally ethane and optionally nitrogen, which latter gas stream is subjected to a second sorption step resulting in a further separation, finally resulting in a gas stream comprising methane, wherein each sorption step is followed by a desorption step which comprises desorbing the sorbed components originating from the gas stream in question.

Claim (Index 2):
Process according to  claim 1 , comprising\n a reaction step which comprises subjecting a gas stream comprising methane and air to methane oxidative coupling conditions resulting in a gas stream comprising nitrogen, methane, ethane and ethylene; a first sorption step which comprises contacting the gas stream comprising nitrogen, methane, ethane and ethylene resulting from the reaction step with a sorption agent which has an affinity for nitrogen which is lower than that for methane which in turn is lower than that for ethane which in turn is lower than that for ethylene, resulting in sorption of ethane and ethylene by the sorption agent and in a gas stream comprising nitrogen, methane and ethane; a first desorption step which comprises desorbing ethane and ethylene sorbed in the first sorption step resulting in a gas stream comprising ethane and ethylene; a second sorption step which comprises contacting the gas stream comprising nitrogen, methane and ethane resulting from the first sorption step with a sorption agent which has an affinity for nitrogen which is lower than that for methane which in turn is lower than that for ethane, resulting in sorption of ethane by the sorption agent and in a gas stream comprising nitrogen and methane; a second desorption step which comprises desorbing ethane sorbed in the second sorption step resulting in a gas stream comprising ethane.
