Abstract

A method for producing ethylbenzene (EB) comprising introducing to an oxidative coupling of methane (OCM) reactor an OCM reactant mixture comprising CH₄ and O₂; allowing the OCM reactant mixture to react via OCM reaction to form an OCM product mixture comprising C₂H₄, C₂H₆, water, CO, CO₂ and unreacted methane; separating the water and optionally CO and/or CO₂ from the OCM product mixture to yield an EB reactant mixture comprising C₂H₄, C₂H₆, unreacted methane, and optionally CO and/or CO₂; (d) introducing benzene and an EB reactant mixture to an EB reactor; allowing benzene to react in a liquid phase with the ethylene of the EB reactant mixture to form EB; recovering from the EB reactor an EB product mixture comprising EB and unreacted benzene, and an unreacted alkanes mixture comprising C₂H₆ and unreacted methane, and optionally CO and/or CO₂; and optionally recycling the unreacted alkanes mixture to the OCM reactor.
