A process is provided for the concentration and recovery of propylene from propane by a pressure swing adsorption (PSA) process using an adsorbent comprising AlPO-14. A PSA process is used to remove propylene from a C3 hydrocarbon stream comprising propylene and propane. The PSA process of the present invention can be employed in petroleum refining and petrochemical processes to purify and separate propylene from mixtures of propylene and propane without fractionation.

1. A process for the production of a high purity propylene stream from a mixture comprising propane and propylene, said process comprising:a) contacting the mixture with a selective adsorbent comprising AlPO-14 at a temperature between 120.degree. C. and below a temperature of incipient reaction at an adsorption pressure in an adsorption step to provide an adsorption effluent stream comprising propane; and b) desorbing propylene in desorption step at a desorption pressure lower than the adsorption pressure to provide a propylene product stream.
