Pressure swing adsorption operations for the selective adsorption of a component of a gas mixture is carried out, in multi-bed systems, so that the gas released from a bed during the cocurrent depressurization, provide-purge step is passed partly to another bed and partly to an external vessel. The gas in said vessel is thereafter used to partially repressurize said other bed after it has completed its purge step.
