A method of separating gaseous components. An equilibrium-limited, gas phase reaction is conducted in a centrifugal separation device and at least a portion of a first product of the reaction is separated from a reaction mixture comprising at least one reactant and at least one product in the centrifugal separation device. In another embodiment, the equilibrium-limited, gas phase reaction is conducted in a reactor and a reaction mixture is transferred from the reactor to the centrifugal separation device for separation of at least a portion of the first product. A gas centrifuge comprising at least one rotor and a catalyst is disclosed, as is a gas cyclone comprising the catalyst. The catalyst is formulated to increase a rate of the equilibrium-limited, gas phase reaction.
