A process for the rejection of carbon dioxide from a natural gas feedstream comprising a gas permeable membrane and a multiple bed pressure swing adsorption system to produce a fixed gas product having a desired concentration of carbon dioxide. The permeate stream from the gas permeable membrane system is fed to the PSA unit and a stream essentially free of carbon dioxide gas from the PSA unit is compressed and blended with the non-permeate stream to form the mixed gas product.
