초록 ▼

In the increase of the hydrogen content of a gas rich in hydrogen by contacting the gas with a zeolite which selectively adsorbs the gases other than hydrogen to leave the non-adsorbed gas enriched in hydrogen, and then desorbing the adsorbed gases from the zeolite, the improvement which comprises employing as said zeolite Ca-zeolite X granulate in which at least about 50% of the Na initially present in the zeolite has been replaced by calcium.
