Apparatus and a process for producing high purity oxygen containing not more than 1 ppm by volume of hydrocarbons. An oxygen stream containing up to about 100 ppm by volume of hydrocarbons is subjected to cryogenic temperature swing adsorption in an adsorption bed containing calcium-exchanged type X zeolite, type 5A zeolite or 13X zeolite, for the removal of the hydrocarbons and any nitrogen present in the oxygen stream.
