    Abstract: The invention relates to a reactor system for oxidative coupling of methane (OCM), comprising: reactor system for oxidative coupling of methane (OCM), comprising: (a) an inlet configured to receive a reactant mixture; (b) a reaction chamber having an upstream end and a downstream end such that the reaction chamber extends from the upstream end to the downstream end, and the reaction chamber comprises a catalyst bed having a catalyst composition having at least two catalyst components: (i) a low selectivity catalyst component; and (ii) a high selectivity catalyst component; and (c) an outlet configured to recover a C2+ hydrocarbon product mixture from the reactor system; wherein the reactor system is configured such that the reactant mixture substantially contacts the high selectivity catalyst component prior to contacting the low selectivity catalyst component. The invention further describes a process for the production of C2+ hydrocarbon product mixture using the present reactor system.
